Students will be able to:

-explain that atoms are the smallest unit of an element and are composed of subatomic particles.

-describe how the atomic theory was developed.

-review changes in matter.

Students answered the following questions in their bell ringer folder:

A. Nonliving and living things can be made up of combined elements.

Jonah is completing the table shown below. What are the best headings for Columns A and Columns B?

A.Column A: Atoms; Column B: Mixtures
B. Column A: Molecules; Column B: Atoms
C. Column A: Elements; Column B: Compounds
D. Column A: Atoms; Column B: Elements

         Column A                          Column B

Na	N
Ca	CaCl2
Fe	Fe2O3
Pb	PbN6

Students reviewed combining atoms to make the different types of mixtures and compounds, elements, and molecules. 

Students then did the Have A Ball lab. Students not completing the data should go home to complete data so that group data can be shared on Monday in class.

Home learning 17 can be found at the top of this blog. In addition, students are to practice their reading strategy, by reading the closed captioning information from a science show. The handout should be signed by a parent or guardian.
