Materials Requirements for GEMS Teacher's Guides.

What materials will I need to present a unit? This is one of the most frequent questions we are asked.

Every effort is made in GEMS to use materials that are easy-to-find, inexpensive, and safe for classroom use. GEMS activities emphasize everyday materials — paper, pens, tape, plastic cups, scissors, and the like. But occasionally we require slightly more complex and difficult to find materials. After all, the materials needed to create a streambed to model erosion on a mountainside are more complicated than those needed to experiment with bubbles. (But both are well worth doing!)

With each title below is a PDF document with the materials lists scanned directly from the pages of that book.
