Making Learning Irresitable for Over 25 Years. Making Learning Irresitable for Over 25 Years.
Classification Unit (animals) Test

Thursday is the test over animal classification. Please review the sections (most of 4 chapters) that were assigned for reading and lessons.

Remember that I am allowing you to use your vertebrate comparison table, the study guide on mollusks and arthropods, and the visual organizers that you created for cnidarians, sponges, and 3 worm phyla. Of the 9 major animal phyla, you have a written resource on 8 of them to use during the test. There will be a few questions about phylum Echinodermata so review those pages in your book.

You may work on presentations following the test.

I will collect the Owl Pellet Lab activity and your bone cards tomorrow. Please review your answers to see that you have it completed.

We will watch our iMovies on Friday and you may bring a movie snack to enjoy if it is not too messy.

Checklist for Project assignment

Today in class we watched a video about birds or mammals, depending on which class you were in. The Vertebrate Comparison Table final two sections on birds and mammals are due tomorrow. Most students have completed them already and I will check them tomorrow.

In class, we discussed what was due to me next Monday and students received a handout outlining the details.

Final Report Checklist

Any students working with protist projects should check with me tomorrow as we hope to be able to capture digital video at that time.

I have cultures of paramecium, euglena, and amoeba for your use if needed. See me for help. Time is running out. This is not a project that can be done in one afternoon!

Project Research Continues

I am so pleased that most of my students are scheduling time to complete the data collection for their projects. Several students have stayed late to work on their experiments and most are finishing their work. Wednesday was our last visit to the park as a class to work on projects.

Next week I will be available on Monday 5/7, Wed. 5/9, and Thurs. 5/10 until 5:30 and every morning from 8:45 until 9:10 for project work. The final report is due on Monday 5/14 at the beginning of the assigned class.

Science is "all about" analyzing the recorded data. How scientific have you been in your record keeping? What do your data indicate about your project hypothesis? Please keep in mind that I am looking for evidence of scientific thinking as your analyze your data and evaluate your work. I will give you a reminder checklist of what to include in your final report during class on Monday.

This week we have been comparing animals and examining how they are classified. Students have been working on an oversized vertebrate animal comparison table Thursday and Friday. The last two sections on birds and mammals are due on Tuesday. The animal unit test will be next Thursday.

We will evaluate our imovies and vote for the Student's Choice winners in each class on Friday 5/11.

Video Project timeline

Student teams should complete the clean recordings of the voice over and download the desired clips from the server by Friday. Continue to edit your movie to marry the audio and video components.

A clean, edited copy of the script and bibliography with your team's rubric should be in your team folder at this time.

Please make a decision about your music by next Monday. You may bring in CDs, use some of the free share music that is available, or record your own music track in Garage Band.

The artistic impact and message of your movie can be enhanced with the "right" music, so give it some thought.

The Title and Credits should be added to go with the music track. Do not use last names of students in your credits and remember to credit your music and video sources.

Your project should be finished by Thursday (3/29) with a little time left on Friday for final editing (just a few tweaks), completing the self evaluation using your rubric, and copying to my external drive.

This research project counts as test grade.

Data Collection in the park

Tuesday we had a change in plans from my earlier post. We will continue our experiments on the human body systems unit later in the week. Wednesday we will be Career Cruising in the maclab with guidance counselors.

Most students submitted their research plans and approval forms on Friday or Monday and were ready to begin data collection on Tuesday...and the weather was unusually nice...so we headed outside for class to work on projects.

Students are doing their individual research while collaborating with a research team for collecting data. All students should be recording data in their project logbook and have a handout to describe what to include there.

Independent study projects are ongoing this year and I look forward to hearing what students are learning about water quality, the forest, amphibian populations, etc. Student teams will have the opportunity to post their work on our Sweat Mountain Park blog beginning soon.

Genetics Test Thursday

There will be a test over genetics tomorrow. We reviewed in class today and students should have several assignments from chapter 3 to study. Remember to pay extra attention to the diagram on protein synthesis found on pages 110-111.

Students who did not make an 80 or higher on the last test are reminded that the Chapter 3 Guided Reading Workbook pages are due to be checked by me for a homework grade tomorrow.

Experimental design diagrams and procedures are due tomorrow. This assignment may be written by hand or typed. Our lesson on Monday was about using an experiment design diagram to evaluate the elements of an experiment. I hope that lesson helps you in your planning. See the handout and rubrics that are on the back. I know that several students will need to revise their experiments, so do not worry about getting it perfect before submitting it to me. Do turn something in.

Genetics Studies

Sponge Bob and the Bikini Bottom gang have been lending a hand in our classes this week as we learn how biological traits are passed on to successive generations (standard S7L3). Mendel worked with his peas to demonstrate how probability could be used to figure out that some traits are controlled by factors (genes) that have a dominant form and a recessive form. We have been using Punnett squares to determine the probability of various outcomes in the land of Sponge Bob (WS#1 and 2) and today we investigated the phenomenon of incomplete dominance with Sandy's favorite Poofkin flowers (WS #3). I think that most students have it figured out!

Other terms that we have learned this week include: homozygous, heterozygous, purebred, hybrid, allele, gene, chromosome, incomplete dominance (similar to co-dominance), genotype, and phenotype, asexual reproduction, and sexual reproduction. Please make sure that you are reading and studying the chapter pages that go along with our studies in class (pages 86-99). Do the workbook pages also if you did not have at least a B on the last test.

I checked WS # 2 for a HW grade today. If you did not finish it, please do so and give it to me tomorrow.

Your homework for the week has been to work on your report of background information and your project research plan.

Cell Cycle today...Test Monday

1. Today students took notes on the cell cycle using the textbook on pages 72-79. The notes should give details about what is happening in each of the three stages in the life cycle of cells.
2. Students then connected to my blog and the Trackstar lesson on the Reviewing the Cell Cycle that was posted earlier. The Online lesson on Onion Root tip mitosis (1st site) was completed with the data and analysis written on the same page as the notes.

Take time tonight to check out the other sites on the track to learn about the cell cycle.

Homework is to begin reviewing for your upcoming test, which is scheduled for next Monday. It will cover how cells grow, divide, and make/obtain needed materials (all of chapter 2).

Also on the homework board is to continue researching your possible park questions/ research topics so you will be able to make a good choice for your project.

I will issue the Life Science Guided Reading and Study Workbooks tomorrow. Students who did not earn at least 80 on the last need to compete the lesson pages for chapter 2 and get them checked before next Monday so they will be better prepared for the next test.

Research in the Park

The park is your laboratory this year!

What questions do you want to spend your time investigating?
Are you interested in biology, physical science, Earth science?
Are you interested in the organisms that live in the natural spaces in our community? Do you care about how the natural areas are used by people?

Think about all of the possibilities for field studies.

Your goal is to come up with a project involving data collection that is related to Sweat Mountain Park and/or other similar areas in our local environment. It could be a controlled experiment, a data collection and analysis type project, or even a service learning project

Service learning projects are great if you want to get involved with “making a difference” in the park. Need some money to make your project happen? Do not worry, the Mabry Science Club may be able to help you. As first place finishers in the Youth Environmental Symposium of 2005, they earned a cash award that can be used for worthy projects. The club may be interested in helping you with your project. You will be required to submit a proposal that details your plan to request funding. (More on that later.)

We have many materials at school that should help you with you study (water quality testing kits, microscopes, ProScopes, data collection probe-ware, boots, materials for collecting stream macro-invertebrates, GPS devices, other measurement tools, etc.) so keep that in mind when planning your investigation.

Right now you should be exploring some of the many ideas that you have for your park project. Use the pre-research FLIP it! that Mrs. Hendrix prepared for you to get you thinking and finding information about your ideas. You will need to have a working idea for your project by next week. Here are some broad categories of research ideas.

Earth Science:

Geology
o Soil analysis
o Erosion studies
o Geologic history of the area

Meteorology
o Weather impact on ???
o Rainfall/runoff studies
o Light intensity questions
Hydrology
o Stream water flow studies
o Chemical/physical parameters of the water
o Watershed questions

Life Science:

Impact of people on the environment
Soil organisms
Water organisms
Life cycle questions- tadpoles, insects, plant species
Assessment of what lives in the park (trees, wildflowers, fungus, lichens, insects, etc.)
Opportunistic species, invasive species, exotic species, native plants, etc.


Physical Science:

Light intensity
Temperature

I have heard some of your great ideas and am looking forward to helping you with your projects this year!

How do cells get they energy that they need?

Today we checked the photosynthesis and respiration comparison tables. I will collect this assignment tomorrow for a grade.

Students took time to record the Grass Head lab activity in science journals today. Title, Problem/Question, Hypothesis, Procedures, Data, Analysis and Conclusion should be included in the write-up. Everyone measured 10 representative grass blades from their grass head to enter as their data. The average for each grass head was written on the board to be be combined and averaged for the class data. We will finish the analysis of data and conclusion tomorrow.

We discussed how cells get the energy that they need when oxygen is not available. Alcohol fermentation and lactic acid fermentation were compared.

Homework tonight is to read pages 72-79. We will learn about the cell cycle this week.

Compare and Contrast

Here is the assignment that we worked on in class today. Read and study pages 65-69 to learn more about respiration. Your organizer and summary should be completed by Monday.

Compare and Contrast photo:resp.doc

Also, take some time this weekend to explore your other possible park research questions using the format that we used in the media center on Thursday.

Photosynthesis and DEAR

DEAR time was today with a continued emphasis on the skill of understanding conclusions.

We also corrected Test 2 and watched part of a DVD on Photosynthesis. We will finish the video and lesson on photosynthesis tomorrow.

For homework tonight, READ and STUDY pages 61-65.

Our guiding questions:

What happens during photosynthesis? How do chloroplasts function to store energy for a cell?
Standards: S7L2-Describe the structure and function of cells, tissues, organs, and organ systems.

S7L2.a Explain that cells take in nutrients in order to grow and divide and to make needed materials.
S7L2.b Relate cell structures to basic cell functions

Our grass-heads are looking great! We will analyze the data on Monday or Tuesday of next week.

Questions for Research

Today EQ: If cells are the building blocks of life, what are the building blocks of cells?

In class today, we used molecular models to learn about carbohydrates, one of the four types of organic compounds found in living things. Students completed a lesson worksheet and should have it in their binders.

Tomorrow our class will visit the media center to work on finding a research focus question for independent study projects this year. Students should have several questions from last Thursday's assignment in the park to use as a starting point.

For homework tonight, write down at least three interesting questions that are suitable for research that is connected to Sweat Mountain Park.

posted on: September 26, 2006

Connect 2 Science

Today students visited the Connect 2 Science site at Mabry's Global Learning Collaborative to learn about this interesting opportunity and to read Dr. Berry's post. We had a short lesson about how to write interview questions that might be appropriate for posting on the site.
Connect 2 Science

For homework tonight: Write three quality interview questions and also tell why you would like to be a student author for this project.

The remainder of class was devoted to gaining an understanding of the types of chemical compounds that are in living things. We began working on an activity about carbohydrates using molecular models. We will continue with this tomorrow.

Our grass heads are just beginning to show tiny roots and tomorrow we will be sorting them into two groups per class- an experimental and a control group. Each class will come up with a research question.

Questions Drive Research

Today was a great day for our second visit to Sweat Mountain Park. The weather was perfect and our outing was fun. During our first visit, students recorded observations and made inferences. For the second trip to the park and the second step in our research process, students were asked to come up with several questions for research. It is hoped that these questions will lead to interesting and significant studies. Sometimes this is the most difficult aspect of research--- deciding the question. We will continue our research and question finding next Wednesday with a visit to the media center.

Friday classwork and homework

How do plant, animal, and bacteria cells compare?

Classwork- create a Venn diagram to analyze and compare the characteristics of plant cells, animal cells, and bacteria cells. See your text pages 34-42 and 192-194 to find details to include in your comparison. Next, write a paragraph to summarize what you have learned.

Homework- Read about the cell in it's environment (pages 56-60). This is section 2 in chapter 2. We will begin the analysis of your egg data on Monday and I will explain what you should include in your report that is due on Friday, Sept.20. (See the rubric on the back of your lab handout.)

There will be a test over cell parts and functions on Wednesday, Sept. 20.

We had some great Job Descriptions and Want Ads turned in today! I am looking forward to evaluating them.

We said goodbye to our eggs today. Today was fun, pretty messy, interesting, and a little disgusting. We made many interesting observations that will be shared in our reports next week.

Cell Organelle - Job Description and Want Ad

Link here for the assignment. Remember your login? It is the same as the lesson/activity on cell size. The quick link is 248.

For homework, students should prepare a first draft of a want ad or job description for their team's organelle. It should be typed and ready for editing in class. The final product is due on Friday.

Remember each person should do only one of the assignments...the job description or the want ad.

Here is a sample want ad that I found online; it is adapted from the work of a student in South Lake, TX. Can you guess the organelle?


“Looking for a great opportunity to lead? Do you enjoy making decisions for others? Is guidance your strong point? If so, we are seeking to fill a managerial position. We are in need of a control center for a cell. Must be able to operate a cell. Should have solid experience reading and de-coding DNA. Should exhibit strong leadership skills. Benefits include: placement in low-stress arm cells, long life guaranteed...you don't die; you just divide and multiply! If interested contact The Body at 817-8WE-CELL.”

Your want ad should be created with a 2.5 in wide space for the text. Change your margins or create a text box for your ad. We will try to piece our ads together to make a "page from the newspaper" to post in the room. Do not include the name of your organelle in the ad so other students can try to figure out which one it is.


Your grade will be determined by how well you communicate what you have learned about your organelle. See the rubric below.

Cell Parts

Wednesday in class we watched a quirky DVD about the various parts of a cell. Students created a three column table to compare the parts of cells that included the cell part, structure of description, and functions using information from the video and the book. We will complete this assignment later this week. This information will not be evaluated on Friday's test. We also used some props in class as analogies for the cell parts. Can you think of another good analogy for a particular cell part? Do you know what types of cells are we using to learn about the organelles...was that prokaryote or eukaryote?

Our focus question: What are the parts of cells and their functions?

EQ: Why are some parts of cells called organelles and others are not?

DEAR on Thursday. We will continue to find examples of cause and effect in our reading.

Observations in the Park

Classes visited Sweat Mountain Park today to make and record observations and inferences. We are fortunate to have a such a nice natural park space that is adjacent to and shared by our school property. In class we have been learning about the scientists who made observations that were instrumental in the development the Cell Theory. These naturalists were fascinated by the natural world around them and made many observations of everyday things. Today students gathered a few items to view and learned how to use the stereoscopes. You would be surprised to see how interesting a butterfly wing appears when maginfied. Acorns, mushrooms, pinestraw, rocks, insect larvae, leaves, etc. were all objects of study today. As we continue with our study of the habits of scientists, it will be interesting to see what interesting questions arise in my classes for experimentation and research.

Wednesday update

It was a pleasure to meet the parents of my students at Open House on Tuesday night. I hope that everyone has made arrangements to access I-parent by now so you can see how your student is performing in class.

In class on Wednesday, we analyzed our data from our activity "How big is that cell?" and discussed the answers to Part IV questions.
It will be interesting to see how close our estimates are to the actual sizes of the various cell types. (I wonder if any of my students know how to find that information?) In class, we also completed a note taking activity (concept definition map available below) based on pages 18-25 "What is Life?" reading assignment.

Organism Concept Map

For homework:
Please read pages 27-33 "Discovering Cells" and record notes as described... In you notes, State the Cell Theory and create a table to record the contributions made by Hooke, Leeuwenhoek, Schleiden, Schwann, and Virchow to our understanding of cells that led to The Cell Theory.

Student journals should now have several items to be graded: A reflection on the importance of accurate record keeping, Experiment using Gummi candies, activity on "How to use a Microscope", and the activity "How big is that cell?" I will begin checking them today, please make sure that your journal is on the shelf with your class.

How big is That Cell?

This is the activity that we are working on in class. We will complete parts I. II. and III in class. You should complete Part IV for homework - due on Wednesday.

How Big Is That Cell?
Learn the basic theory and methods of optical microscopy.
Use a compound microscope to examine and determine the relative size of plant, animal, and bacterial cells.
What you will do:
Recognize the concepts of magnification and optical inversion
Prepare a wet-mount slide and examine and measure a standard sample
Examine and measure different cells

posted on: August 27, 2006

Microscopes

Students were introduced to microscopes in today's class activity. Following the lesson, students should be able to:

1. use the appropriate terminology to describe the parts of the microscope
2. demonstrate the correct use of a compound light microscope
3. calculate the total magnification of the various objectives on the microscopes
4. explain how to prepare a wet mount slide

I asked students to check the blog tonight for some interesting links relating to microscopy. Check them out.
How do images from compound light microscopes differ from the images from electron microscopes? What are the advantages and disadvantages of each? Which do you prefer?

Another thing to ponder---how do advancements in technology affect our understanding of the natural world?

P.S. Today (officially), our solar system has only 8 true planets. What a wonderful example of how science is constantly changing because of new information. My 6th period was most mournful of the demotion of Pluto to dwarf planet status; I was surprised that they were so passionate. They are already trying to rethink that familiar phrase..."My very earthy mother just served us nothing (or was that nachos?)" .

Books will be assigned on Monday! It is time for us to begin learning about living things and the nature of their cells.

Parents please plan to attend open house Tuesday evening. I am anxious to meet you.

There is no homework this weekend. We will complete the lab write up and lesson extensions on Monday. Journals will be checked next week, so have them completed and on the shelf. You should have one writing assignment, an experiment on Gummi candy, and the activity on using a microscope in your journal.

Getting Organized

I once heard someone say about scientific record keeping..."If you don't write it down, then it didn't happen." We discussed this notion as we set up journals and notebooks today. Students made their first entry in their journals by writing a reflection on: What is the value keeping organized and accurate records in science?

Pig dissection week at Mabry

The 8 algebra students who are in my 4th period will be able to make up the missed lab work before school on Tuesday, after school on Tuesday, or during one or both connections (with teacher approval). Please check with your lab partner and arrange a time for me to meet with you. Do not worry about getting it done. You will be able to work out a solution for the make-up some time this week. Concentrate on doing your best on your Algebra end of course exam.

Keep in mind as you work that you are dissecting to reveal the systems of the fetal pig and to relate them to the human body systems. Work at a careful pace and review what you have learned each night. Complete the lab questions that go along with your dissection each night or after you clean up each day. There will be a lab test on Friday.

Mr. Bojangles visits class

We had a special guest in our class on Wednesday (Chad said it was his birthday treat). Thanks goes out to Katlyn for providing my 4th period with the special treat of watching Mr. Bojangles capture his dinner and swallow him. After lessons in herpetology class on Jekyll and actually getting to hold snakes and other reptiles there, it was fun to get up close and personal with a snake. It was a nice short break from our wildlife documentary research and script writing. Here are a few pictures:

Observing Protists

Monday and Tuesday we observed living protists and analyzed their features to discover more about how they are classified.
You should have at least 6 very detailed, labeled diagrams of what you observed in your journal. Wednesday is our day to wrap up our investigation.
For homework on Monday you should have read pages 218-227.

The chapter 6 test will be on Thursday. You should be preparing for it now. Things to consider that are on the test are (all of chapter 6): classification, the 6 kingdoms, characteristics of the 2 bacteria kingdoms, viruses, and details from our "microbes and you" program on Friday. Study your vocabulary! We are currently working in chapter 7 and this material will not be featured on the test. (You should know the characteristics of protists because they are one of the 6 kingdoms.)

Observing Protists Lesson skills:
Prepare wet-mount slides of protists
Focus and examine slides using a light microscope at various magnifications
Draw, diagram features, and record other observations of protists
Compare and contrast various protists

Projects Due on Tuesday

Tuesday, Jan 17th is the due date for student independent study projects. Each student should have a display board, a detailed logbook of their original work, and a formal report to turn in on Tuesday. Students should be working on data analysis (tables, graphs, and discussion). Remember to reflect on whether or not your data support your hypothesis for your conclusion. See the Science Fair Basics handouts and others for details. I will provide a summary handout for you tomorrow.

The class Science Fair will be next Thursday, January 19th. Please plan to attend before and after the Jekyll Parent Information meeting that is scheduled for 6:00pm. More details will follow.

Please note that students are NOT required to do the Abstract as described in their handbooks. Only students who are going on to the district fair will be asked to do this.

Today I learned that some students are not quite finished with their experiments. We discussed the problems with procrastination and the unexpected happenings that can crash last minute efforts. It is now "crunch time"! Get busy working on your final items.

I have let students know that I am available to assist them with creating their computer generated graphs of data before and after school for the rest of this week. I will get here by 8:15 for the early crowd and I will stay until 5:30 for the later crowd.

If you want me to cut letters for your title on your display, please write out what you want and attach it to the paper that you want me to use and I will get it done on Wed. or Thurs. afternoon.

Extracting DNA

Today we examined two different lab procedures for extracting DNA from living (once living) things. We compared the two processes and then brainstormed several experiment topics based on the variables of the activities. Small groups of students worked together to decide which variable to investigate and then planned their individual experiments.
Tomorrow we will do our experiments. I am shopping for additional materials tonight and students may need to bring some things from home. So... Parents do not worry if your child asks if they can have a bell pepper or some spinach to take to school.

One of our procedures involves the use of a blender and I have asked students to ask their parents if they can bring one from home. If not, we will make do with the one that I have.

Update on using e-rater

I know that you tried. Everyone had problems with submitting their papers for evaluation. Here is the NEW procedure for submitting:
1. Create your report using Word or something similar. When you are finished with your report, highlight and copy it.
2. Log on to PHSuccessnet using the link on a previous post. Remember that you used your lunch number and your first name as your logon and your password.
3. On the far left drop-down menu, select e-rater instead of essay builder.
4. Use the edit - paste function to copy your report in the space provided. Do not try to submit the bibliography.
5. Select either C9 -Cause and Effect or C6 -Description as the type of essay. (I know that it does not seem to fit, but the scoring for your writing works fine in these functions.)
6. Submit

I will check the scores and print you a copy of their evaluation. Two students in my 6th period both earned 6 out of 6 on their writing thus far. Good luck everyone.

If you were one of the few students who did not turn in a research report today, then you will need to do it tonight for homework and earn a late grade.

Other Evidence for Evolution

How can DNA analysis or amino acid sequences of Cytochrome C of organisms today be used to support the theory of evolution?

On page 170 in your text, you will find an activity that examines the use of amino acid sequencing in Cytochrome C protein to compare the relatedness between orgainsms. During class we worked in cooperative teams to compare the amino acid sequences for the Cytochrome C protein in horses, donkeys, whales, chickens, penguins, snakes, moths, yeast, and wheat using a more detailed handout. A cladogrom was then devised based on the data.


Today we checked answers to the study guide questions relating to section 3 that were assigned as homework on Monday. If you were absent, you may get a copy of the handout when you return.
Everyone should finish the study guide for homework tonight.

The Evolution unit test (Ch. 5)is on Friday. Remember that all students who did not earn 80 or higher on the modern genetics test are required to do workbook pages 47-56 and show them to me for a grade before the test.

What is natural selection? How do you think variation of color in a species might affect natural selection?

Some teams had time to get started on part 1 of the activity. Tomorrow we will complete the activity and the analysis of data.
There is no homework for tonight.

Conference Week

Conference Week has been a pleasure this year. My students are interesting and wonderful individuals and they have strong and caring parents supporting them. It is useful to have the insight that parents offer about their children as we work together to maximize the educational opportunities for each one. Communication is so important as we progress through the school year. Please do not hesitate to let me know if you have concerns. Thank you parents!

In our shortened classes this week, we have been working on understanding how specific traits are passed from parents to offspring. We have learned how to use Punnett squares to explore the probability of possible outcomes in cases where traits are controlled by a single pair of alleles using examples from Spong Bob and the Bikini Bottom gang. We have also worked through some cases of imcomplete dominance and discussed codominance. Check out our Smiley Family Portraits to see the many outcomes that could arise from Mr. and Mrs. Smiley.

Summarize your science article

For homework tonight, write a one paragraph summary of your science article. You may write your summary on notebook paper neatly in pen or you may type it. Remember- DO NOT begin with "This article is about..."

You should reference your article on your summary. To do this, you should create a bibliography of your one reference using the format required for the source of your article. You can find this information needed to write your bibliography on the media center blog or use the "citation machine" site that I posted in general information. You should use the MLA format option. I will demonstrate this for you in class tomorrow. If you do not understand how to do it tonight, I will show you and you can add the reference/bibliography later.

Microscopes

Tuesday we will learn how to use microscopes and the names and functions of the various parts. Students will set up their science journals for an introductory lab on microscope use.

As a notebook assignment, you should draw and label a diagram of a microscope. Create two column notes for the microscope parts and their functions as found in your text on pages 802-803.

Setting up your science journal:
-You should use a blue of black pen to record information and data in your journal. Take your time to write neatly. Your journal should be organized and legible. Write in complete sentences when analyzing data and recording observations. You may write on both sides of your paper, but may not want to if it is messy (sometimes the ink goes through the paper). Drawings may be done in pencil initially and outlined in pen later.
-Number your pages consistently (all the same place and size number) beginning on the first page with (1). Number from 1 to 50 just to get us started. You can finish numbering later when you have more time.
-Page (1) will be your title page for the journal. Center your name on the top line; write AC Life Science Journal below your name; Teacher- Mrs. Carroll follows; and 2005-2006 below that.
-Write "Table of Contents" on the top line of page (3). Below that, write the headings "Page" and "Activity" and "Date" across the page as column headings. I will show you in class how this should look.
-You will begin recording your first activity on page (7).
