Product Details

Students mix two solids and a liquid in a closed container and observe a dramatic series of changes—temperature changes, color changes and changes in state. What interactions are responsible for each observation? Are the changes independent of one another? In this open-ended, inquiry-based introduction to the scientific method, students first make observations and then design controlled experiments to identify the substances responsible for each change. Designed as a first experience for the chemistry lab, this activity is a fun and easy way to introduce students to the study of chemistry—students can actually hold an experiment in their hands to see and feel what chemistry is all about. Students learn that the scientific method is not a rigid path, it is a process—a process of discovery! Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs.
