Student Research Plans and forms

There was a little confusion about the research plans and forms that students have been working on lately.

Hopefully all questions have been answered and students will be able to complete the assignment and submit it to me for approval on or before Monday, Dec. 11. Remember to include your bibliography.

Parents need to read your research plan and sign in the space for parents on form 1B only. Students remember to tell your parents that I am the sponsor and have studied the rules.

Students who are engaging in studies of salamanders need to have the Vertebrate Animal form and the student teams that are using the bacteria tests that were ordered will need to complete an additional form. The forms are available online below or I will give you one at school. I will work with you to help complete them.

Remember that safety is always the most important consideration. Please make a note in your research plan about safety precautions that you will take as you perform your investigation. You could make a statement about the use of protective eyewear (goggles) if you are using any chemical tests for water quality. If you are getting in the stream to collect or measure, make a note that boots will be used and that hands will be washed following the data collection. Students involved in bacterial studies will be limited to making observations of dishes that are taped shut and I will be in charge of disposal of the dishes after observations. Think about safety during field studies.

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.

Test Wednesday and Report due on Friday

Tomorrow there is a test over cell parts and their functions. You should also be able to compare plant, animal, and bacteria cells. See pages 34-42 in your text to review. Are all the cells in an animal (like humans) alike? What about plants, are all their cells alike? So... what are specialized cells and why are they only found in multicellular organisms?

Here is a link to one of the sites that we used in class today to review the parts of cells.

Cells Alive

Today, students received the following handout that gives more details about how to write the lab report that is due on Friday.

"Egg"-speriment with a Cell

Why did the egg change in mass and circumference in some soaking solutions and not in others?

Students worked on analysis of results from last week's experiment today in class.
In your journal:
1. Create an organized table of your data.
2. Graph your data. Use a ruler; be neat.
3. Describe your results using one or more paragraphs.
4. Explain what you think your data mean. Use diagrams to help with your explanation.

Your final report should be typed and is due on Friday at the beginning of class. Your write-up of the lab should be in your journal and complete by Friday as well.

For homework tonight, complete the three sections of the handout that deal with membrane transport.

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 Project Rubric

Tomorrow is DEAR time in science and we will spend some time finishing our egg-speriment on membrane transport. Remember to bring in the last soaking liquid for your egg.

Cell Structures and Organelles

Trackstar on Cells

Use the above link to get to the list of sites that I have collected for your research on cell organelles. You should become very familiar with your selected cell structure so that you will be able to complete the activities, including writing a job description. We will work on this assignment during class tomorrow.

Why are cells so small?

Today you will complete a web lesson that will be launched from the following site.
Why are cells so small?

You will get a copy of the handout in class.

Please finish this assignment for homework if you do not finish it during class today.

Thursday 8/31

Students enjoyed D.E.A.R. time with a focus of looking for examples of cause and effect. The effect is often implied, not stated. How many examples could you find today?

We watched a video called Assignment Discovery: Cells following our reading. Students were encouraged to take notes and we discussed interesting points following the viewing.

There is no homework for Thursday night.

Students who did not have their Wednesday homework when I checked it today should remember to complete it tonight and show it to me for a late grade tomorrow.

Tuesday and Wednesday activities

Homework:
Your bones quiz is scheduled for tomorrow. You should know the 20 bones in the diagram in your book?
also--
Be prepared to turn in your "A closer Look at Skin" lab activity on Thursday that was finished on Tuesday. You should have completed the EKG lab in class today. Here are the questions, just in case you did not finish your analysis in class today.
1. The electrocardiogram is a powerful tool used to diagnose certain types of heart disease. Why is it important to look at the time intervals of the different waveforms?
2. What property of heart muscle must be altered in order for an EKG to detect a problem?
3. Based on what you have learned regarding electrocardiograms, can they be used to diagnose all heart diseases or defects? Explain.
4. Describe a cardiovascular problem that could be diagnosed by a cardiologist using an electrocardiogram. (you may need to do a little research for this one if you did not read the handout in class).

A Look Beneath the Skin

For homework tonight, please complete your lab report for "A Look Beneath the Skin" found on page 493 in your text. You should have clearly labeled diagrams for your observations and all questions should be answered using complete sentences that restate the question.

also ---Read about the skin on pages 494-500.

Online CRCT review update

Please complete the CRCT practice by Wednesday for 3 homework grades. (Every four review tests counts as a homework grade.) I am checking online to see how you are doing. Remember to choose Teacher Assigned tests to begin. Take time to review items that you are missing using your book. Each chapter has Study Guide sections that summarize key concepts.

We begin the last major unit- Human Body Systems- this week so take time to carefully study your mistakes and use your book or ask during class if you need clarification on a concept.

I have a few students who are doing the review with hard copies instead of online. Remember that you must check your answers and tell me your % score for each test completed.

Owl Pellets and Diatoms

We enjoyed examining owl pellets and the bones that they contain on Tuesday and Wednesday of last week. Each student team removed the bones, identified them and glued them to a card. Their bone displays and student worksheets were turned in during class on Thursday.

During class on Thursday and Friday, students reviewed some of the concepts from our evolution unit by doing an activity about diatoms in Yellowstone lake. Student teams worked on completing this assignment during class today. Our activity using core samples of colored sugar layers to model the concept was fun and a little messy. The analysis should be completed for homework tonight and will be collected during class on Tuesday. (That includes parts 1, 2, 3, and 4.)

Test Corrections

Remember that you have another article summary due this Thursday.
Students should correct their Science Test #1 for homework tonight.
This means that each missed question should be written out on notebook paper and the correct answer written out beside it- not the letter of the correct answer. The corrections will be turned in for a homework grade. If you had one or two points deducted for the experimental design diagram, then you may simply write out the missed part. If you missed 3 or more points on this part of the test, then you should redo the whole thing.

Here is a sample of what you could have written for the experimental design diagram:
Title: The effect of type of plant material on the percent of water that each contains.
Hypothesis: If the type of plant material is a fruit, then the percent of water that it contains will be greater than the percent of water found in the other plant parts.
____________________________________
IV: Type of plant material used
apples grapes strawberries potatoes carrots
1 1 1 1 1
____________________________________
DV: Percent of water in the plant material calculated using the change in mass before and after dehydration (drying)
C: equal size pieces, sliced the same way, same amount of time, same method of drying

Evaluating Experiments

Today students worked in groups to evaluate the design qualities of several experiment scenarios. If you were absent from class today, see me for a copy of the scenarios and directions.
For homework that is due on Wednesday, 8/24, you should select one of the experiment scenarios (2-5 on the back) and complete the experiment design diagram.

We will go to the Sweat Mountain Park (adjacent to Mabry)for our lesson tomorrow. Please wear shoes on Tuesday that are suitable for a walk through the park.
