Happy Holidays!

Have a wonderful  break and enjoy every moment!

Happy Holidays!

Cell Test

Students took the cell test. Any student not in class will have to make up this  test upon their return.
One more day:O:)

Cell Study Guide

Students received the cell study guide and should have completed this in class. If it is not finished it needs to be completed for homework. The cell test is tomorrow. I will be here at 7:30 ish to have a review session for the cell test. All students are welcome to come.

Key Terms and Concept Map

Students received both of these to complete. These are acting as study aids for the test on Wednesday. The test on Wednesday will cover all of Chapter 1 in the Cell book.

Cell and Its Environment

The rest of the Cell Projects were presented today. They were great!
 
Students then began reading pages 32-37 in their books and started working on the worksheet. This is homework!

There will be a test next week on chapter 1.

Cell Projects

Wow! What a wonderful assortment of cells! Students did a fabulous job with these projects. Unfortunatly we did not get to indulge in any of the edible cells today. My  students had to take a survey during their science class so we did not have time for all the presentations and sharing of cells. No problem as we will be able to have some treats tomorrow and this also allows all students to see all cells. 

Students received a copy of cell city analogy which they needed to read and complete by tomorrow.

Extra Credit: Create your own cell analogy using a different model other than the widget. Some ideas are school, factory, home. These extra credits are due Monday December 19th.

Fat Lab

Students did a quick fat lab. Students rubbed certain foods on a paper and determined which foods had the most fat by how translucent their papers became. They then compared their smudges with the food labels to determine whether fat free really is fat free.

Reminder: Cell Projects due tomorrow!!

Chemical Compounds in Cells

I am not in class today however, I am still finding time to post.
Students need to read section1.3 in their cell book - titled chemical compounds in cells. Students must complete the worksheet. This worksheet is homework if it was not finished in class today.

Reminder!!  Cell Projects due on Thursday!!

Egg speriment graph and conclusion

Students worked on graphing their egg-speriment. The graph needs to be two - one for mass and one for circumference. The conclusion needs to be a t least 5 sentences - 1 topic sentence, 3 supporting detail sentences and a conclusion sentence. Make sure to include three possible errors.

Thursday and Friday - Cell Coloring

Students should have turned in their onion/cheek cell lab sheet.

Students then began coloring the animal and plant cells. Students will need to use the book to help them with this. The diagrams are NOT identical to to the book. This color diagram will help as a visual when constructing the cell models.This is homework.

Cell Models due Thursday December 15th.

Cheek Cells and Cell Project

Students changed out their egg-speriment water to the liquid of their choice.

Students then made cells of their cheek cells by taking a swab on the inside of their mouth. We stained these and looked at them with the scopes. Drawings must be labeled and in color. Students will have a few minutes tomorrow to make another cheek cell slide and finish the high power drawings.

I assigned the Cell Project today. A model of a cell (edible or a hanging model) must be made at home sometime in the next week. This project is due Thursday December 15, 2011!! I included the requirements for the edible model. The non edible requirements are the same except the model would not be made of edible materials and must include a string (or a hanging mechanism) so that it can be hung up

The Incredible Edible Cell

You will be required to construct a model of a plant OR animal cell. All
models must be made out of edible materials that will remain fresh at least 3 days
without refrigeration. Avoid using materials that have an unpleasant odor or that
may be considered offensive! Nuts and nut butters MAY NOT be used
Each model must include all of the following organelles:
• Cell wall (if plant cell) • Ribosomes   Cell membrane • Mitochondria
• Nucleus (nucleoleus and chromosomes) • Vacuoles
• Cytoplasm • Lysosomes (if animal cell)
• Endoplasmic Reticulum • Chloroplasts (if plant cell)
• Golgi Bodies
Grading:
Grades will be based on the following questions:
Ö Is your name on the project?
Ö Is the cell type identified? Tell if it is a plant or animal cell.
Ö Is the model a 3-D representation of a plant or animal cell?
Ö Are all the organelles included? (10 for plants cells, 9 for animal cells)
Ö Are the organelles correctly labeled? Each organelle must be labeled with its
name and function. You may label each organelle or use a key.
Ö Are the relationships between the parts (if any) shown correctly? Are the
ribosomes on the endoplasmic reticulum? Is the endoplasmic reticulum
near the nucleus? If a plant cell, are the chloroplasts around the vacuole?
Ö Are the materials acceptable?

You may use the following materials, but they cannot count as part of the cell:
container, plastic wrap, paper, or toothpicks. Keep in mind that these projects will be
eaten after they have been graded!
BONUS: You could be awarded with a bonus (5 extra credit points) if your project is
selected to be the Most Accurate, Most Attractive, or Most Disgusting. Students will
vote to decide the winner in each category.

Onion Cells

Students had to redraw their onion cells. Onion Cells are not boxes or rectangles. Students had to look VERY carefully at their slides and redraw what they saw under low and high powers. Questions 1-7 on the onion sheet must be answered.

  Students MUST bring in a liquid of their choice for tomorrow to soak their egg!

Day 4 Egg-speriment and onion cells

Students put their eggs in colored water today.
Students must bring a liquid of their choice(as long as I OK'd it) for Wednesdays egg soak.

Students created onion slides to look at individual cells. The cells were stained so that students could see the cell membrane, cell wall, nucleus and cytoplasm. Students needed to sketch their cells. The grade will be heavy on the accuracy of their sketches. Students will finish the onion cells tomorrow and then start on the cheek cells.

Day 3 Egg-speriment

We corrected the worksheets from looking inside cells. Students then observed their eggs and changed the vinegar to water. There is no homework.

Looking Inside Cells

Students read pages 16-24 in the cell book. They must complete the worksheet. This is homework. Please use the on-line book. Remember that the username is one of three things: student ID# OR student ID# with a 0 at the end, OR the first 8 letters of first and last name. The password is 7Science.
