water-as-air+demonstration

This is an activity ([]) I've used previously to teach about air pollution. I modified it (removed the part about dry cleaning and modified the part about mowing the lawn as I was working with elementary school students) and believe that it could be modified again for use in the 1st grade classroom at Tamarack (some of the content will need to be simplified for this audience). Another thought I had for modifying this curriculum is instead of using food coloring, using colored kool aid mix. Benefits of kool aid- it's cheaper to buy a large quantity of kool aid than it is to buy a large quantity of food coloring, kids can scoop it themselves, and there's a lower risk of dyeing their hands/clothes! Also, because the kool aid would likely not dissolve completely in just a cup full of water, you can talk about particulates in the air. (Michelle)
