"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water? By investigating with a variety of tools and techniques, learners understand how chemistry can help us explore, understand, and solve problems. Activity includes a facilitation guide with potential misconceptions, relevant science infosheets with real-world connections, table sign, and activity training video. All public-facing materials also available in Spanish.
