1. 1 National Science Foundation Kids' Science Challenge Research Project by Claire Dworsky CE2-B, Lycée Français la Pérouse Comparing Water Runoff from Synthetic Turf vs. Grass Soccer Fields

All rights reserved. 2 The question I want to answer:  Can we test different stages of the water cycle runoff from grass & turf fields to see: is one more toxic than the other? is one more toxic than the other? could the water hurt plants, people, animals or ocean life? could the water hurt plants, people, animals or ocean life? Turf Water Grass Water

Toxic chemicals (older fields), bacteria? Crumb Rubber

What do these mean for living things?  Plant and Animal Study See what happens to them in that water See what happens to them in that water
