Co-op, Week 2

We completed two experiments this week:

Experiment 1.2 - Atomic Motion
Mixing food coloring in hot and cold water to see the motion of atoms.

Experiment 1.3 - A Chemical Reaction
Vinegar plus red cabbage juice and baking soda equals a great experiment in chemical reactions. The kids loved this! The baking soda and vinegar mixture created the first chemical reaction, which was to bubble, fizz and inflate the balloon. The second reaction was a color change in the mixture from red/pink to blue/purple.
