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.

SALT LAKE CITY, UTAH – A hands-on chemistry kit developed by Steve Spangler Science for Be Amazing! Toys won one of the most coveted awards in the educational market – the Teacher’s Choice Award. The science kit called Water Wizardry teaches children how to perform incredible scientific acts with amazing polymers that defy the laws of nature. The kit includes more than a dozen science-based activities using non-toxic chemicals that help children better understand the amazing properties of water and the need for water conservation using superabsorbent polymers.
“Chemically speaking, polymers are simply long chains of molecules repeated over and over again. It’s important to know something about polymers because we all need to make informed decisions about purchasing products made from polymers that are recyclable, biodegradable, or reusable,” says Steve Spangler, the creator of an entire line science kits and science toys for Be Amazing! Toys, a Utah-based corporation that manufactures educational toys and learning resources.
“This kit was designed for the young scientist who wants to mix and measure and whip up an erupting concoction without any need for worry on the part of the parents,” according to Spangler. This kit focuses on a class polymers called superabsorbents that absorb up to 500 times their weight in water. “It’s a great way to teach children about environmentally safe materials that can eventually reduce the amount of water we have to use on our gardens and grass.”
“When our kids made a glass of water to erupt into a pile of fluffy snow-like material, it was hard to control the excitement around our discovery table,” says Julie Gintzler, a kindergarten teacher from Maywood Elementary in Indiana. “Lots of activities have a great ‘gee-whiz’ factor, but I was impressed to get the science behind the wow that my kids would understand.”
LearningÂ® magazine first introduced the prestigious Teacher’s Choice Awards program in 1994. Over the years, the program has become widely recognized within the educational market.
