Physical Science 101

DD is in 8th/9th grade Apologia Physical Science. We have done three experiment so far this week. Here's number three on Concentration.

She filled each glass with 1 c, 1/2c, 1/4c of vinegar added a Rolaid to each cup. We watched them dissolve.
Dumped those out, then added varying amounts of vinegar and water to equal 2 cups. Rolaids dissolved faster in the water that had more vinegar.
