Nothing says classroom fun like an invertebrate and a magnifying glass! Snails, earthworms, and roly-poly bugs become the center of attention as pint-sized investigators hone their inquiry and observation skills. They are guided through the inquiry process with a series of "What if?" questions, intended to get them thinking like scientists, by making predictions and testing their hypotheses. The result is an experiment and a class discussion. Tip: Use visual scientific journals to help learners develop early writing and data collection skills.
