Description

Lab-Aids Contaminants & The Water Cycle

In this modeling activity, students follow a molecule of water as it travels through the water cycle. The activity can be used to model both the basic water cycle and the water cycle with biological and chemical contaminants that are picked up along the way. Students can do the activity once, with or without contaminants, or they can do it twice, initially without contaminants and then later with contaminants. Starting 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 (and describes the types and sources of contaminants picked up along the way). Kit includes: a Teacher’s Guide, 28 Student Worksheet and Guides, 12 Water Cycle Cards, 12 white number cubes, 12 blue number cubes, and a Transparency: Sample Responses to Analysis Question 1.
