=**Biology Term 2 - the Chemistry of Life and Cells**=
 * 0.5 Credit**
 * In this course you will study the elements and macromolecules found in living things and the structures and functions of the cell membrane.**
 * opening activity: science terms word ball.**

Complete this packet on the elements of living things. Alternatively you can see me about the chapter work on this topic:

read through the summary noteson the chemistry of living things and use them to help you complete the puzzle based on reading and notes

In assigned groups, complete the poster project on the chemistry of life

review for the test on the chemistry of life by completing a mind map of the terms provided (note: connectors have also been provided. You may choose to cut out the terms or write them on the newsprint yourself. There is no right or wrong way to organize your information as long as you can easily explain why you have categorized / sorted items the way you have.) = = = =

5. think about osmosis by viewing How osmosis works

6. Conduct the 2 minute challenge. Materials: a ziplock bag slightly inflated with air containing a piece of candy, a rubber band Goal: move the candy from inside the bag to outside the bag without breaking the cell membrane's integrity (or allow the air to escape) using only the materials provided. You may not unzip the bag. Explain: the process you used to complete this task and identify the similar process used by the cell membrane

7. Create a model, diagram or demonstration to show either active or passive transport. Introduce your idea with a paragraph explaining what you are trying to show.

8. review osmosis by completing the assignment

9. Conduct the egg lab  **File Not Found**

9. Conduct the elodea osmosis lab

Discuss with the teacher: 10. Elaborate on the statement: A cell membrane acts as a highly selective barrier in diffusion, osmosis and active transport.

review the "big idea" in your small groups; be sure to add to the study guide to make it more complete
