Science teachers can find lesson ideas almost anywhere. For example, during a recent visit to a local dollar store, the author stumbled upon a flower vase filled with water pearls, also known as water beads and jelly beans. She bought several of the bags (search the web to find numerous online sources), and soon began experimenting. Water pearls are a great resource. This easy-to-obtain, inexpensive, versatile, and reusable material instills a sense of wonder in students of different ages and backgrounds who invariably start to ask "I wonder if..." science questions. This article describes three science investigations students can conduct using a single bag of superabsorbent water pearls. (Contains 4 figures.)
