Today you took a homework quiz on the GPB Chemistry video #201: Physical and Chemical Properties and Changes

We then had element project presentations.

Today we took our unit 2 test. You also read an article, “Eating with Your Eyes: The Chemistry of Food Coloring” and responded to questions.

Homework: Due Monday, 9.12
Watch GPB Chemistry video #201: Physical and Chemical Properties and Changes and take notes. Be prepared to use those notes in class on Monday.
