AGENDA
WHOLE GROUP
The students completed the Sugar Water handout as their bell ringer.
We then did a demonstration by dissolving sugar in warm water to solidify the concepts mentioned in the bell ringer.
Students then watched a BrainPop on Compounds and Mixtures. You can watch the video by clicking on the link below and signing in with the UN amsbartow and the password ams13.
We completed the quiz at the end of the BrainPop whole class.
Students then took notes of compounds and pH. You can find a movie of the slide show presentation below.
Students then used red and blue litmus paper and pH paper to test the acidity and basicity of several solutions.
