Description

LAB-AIDS Contaminants and the Water Cycle Kit includes activities and is used to model both the basic water cycle and the water cycle with biological/chemical contaminants that are picked up along the way. Depending upon your situation, students can do the activity once, with or without contaminants or they can do it twice, initially without contaminants and then later with contaminants. Students start at some point where water exits on Earth, such as in a river or a raindrop. Students then roll a dice and consult Water Cycle Cards to determine where their water molecule will go next. After making at least six rolls of the dice, each student writes a story that demonstrates an understanding of their water molecule's travels within the water cycle.
