Kids Go Green with Eco-Friendly Science

The students in Mr. Kane’s second grade class at Wilder Elementary learned about eco-friendly materials and how they can help us all go green. Mix two chemicals together and wait for the reaction. The chemicals produce a polymer called polyurethane foam. Polyfoam has a high R value and is used in furniture, packaging, insulation and floatation devices. Homebuilders spray the polyurethane into the walls of a house to give insulate against hot and cold weather. The lightweight foam expands to about 30 times its original liquid volume and becomes rigid.
