Wednesday was a project workday outside. Many students are working diligently to collect data and finish their project work; others are not. The final report is due on Monday, May 14. I am available to help students after school until 5:30 on Monday, Wednesday, and Thursday of next week.
Following DEAR time in class on Thursday, student groups sorted illustrations, labels, and facts about 8 major animal phyla into groups to create a poster using chapters 10-13. Groups will finish and evaluate their work next week as we continue to learn how animals are sorted scientifically.
Friday students will read chapter 10 and compare and contrast some of the invertebrate phyla using the following assignment:
The other activity for mollusks and arthropods is not available for posting. If you are absent, you will need to get one from me on Monday. We will finish it in class on Monday and examine some preserved specimens.
I am at a workshop today and will hand out progress reports on Monday.

For analysis, please add these questions to your lab activity on Observing Protists in your journal.
1. What characteristics do all protists share?
2. How are protozoans (animal-like portists) classified or grouped? Describe each and give an example.
3. What characteristics do algae share with plants?
4. How would you classify euglena? Explain.
As usual, answer in complete sentences and restate the questions.
We used some class time for project work and planning with teams today. Tomorrow all classes will go to the park. There are about three more weeks for students to collect data to answer their research question.
This week I am available after school on Tuesday, Wednesday, and Thursday. Next week I am available on Monday(April 30), Wednesday (May 2), and Thursday (May 3). The following week there will be after school work sessions on Monday (May 7), Wednesday (May 9), and Thursday (May 10).
The final report is due on May 14. This counts as a test grade. Students will also be required to present their work to their class and post their reflections on their work to the Sweat Mountain Park science blog. Keep working and finish strong!

We will work on our projects during class time inside tomorrow and outside on Wednesday. You have 3 weeks to complete your data collection and/or work on your project. The final report is due on Monday, May 14th.
For homework tonight please write out your research question (or project goal for a few student projects) and the details of what you will do to complete your research and when you will do it. Be specific about the details of what you need to do to answer your question.
Think like a scientist. Remember that you must base your conclusion on your data. Data should be recorded in quantitative measures or counts, organized in a table, and presented in a graph if possible. You should also describe your observations and findings with words.
I am available this week on Tuesday, Wednesday, and Thursday for after school work in the park. You may check out materials and work on your research with a parent supervising.

Students practiced their microscope skills today to observe a variety of cultured protozoans and algal protists. We will continue this lab activity next week. How are members of this kingdom classified and sorted into smaller groups?
Here is an interesting link on Protista.
Are members of Kingdom Protista important to us? What would the world be like without them?

Please complete thework on your "Little Books" so they can be checked and shared with others on Monday.
Do you have a clear message relating to 7th grade science learning objectives? (30)
Are your facts sufficient and accurate? (30)
Is your work neat? (no smeary pencil, easy to read, etc.) (20)
Good use of color and illustrations? (10)
Is your book creative, unique, or interesting? (10)
I will be available to stay after school for students to work on their research / park projects on Monday, Wednesday, Thursday, and Friday of next week. Please make arrangements with me ahead of time if you plan to stay.

Today we discussed the diversity of life found in the plant kingdom and previewed chapters 8 and 9.
We also discussed and checked answers to skill and test prep questions found on pages: 271, 303,337,371,407, and 439.
There is no homework unless you have not yet completed all of the online practice tests.

Remember that you have Teacher Assigned Tests- Carroll Review 6,7,8, and 9 due tomorrow. That means that you should do them tonight for homework.
EQ: What characteristics are most useful in creating and using a taxonomic key? Use a dichotomous key to classify organisms... (S7L1.b)
In class today, student teams created a taxonomic key for 10 items found at the table. Tomorrow we will swap keys and a different table will use them to identify two of the organisms. If you were absent today, try to catch up tomorrow during class.
Here is a good site to summarize some of the concepts that might be on your CRCT next week.
Check out the differences between sexual and asexual reproduction in section 4. Sections 1,2,3,6, and 8 have a summary and questions that might help you remember what you have learned this year also.
