Baggie Chemistry Lab | Endothermic and Exothermic Reactions

Baggie Chemistry Lab | Endothermic and Exothermic Reactions Students explore chemical reactions and their resulting energy changes with this engaging baggie chemistry lab. Learners follow procedures to combine household ingredients in plastic bags, closely observing the vivid reactions that result. Comparing endothermic and exothermic processes, they identify indicators like temperature change, bubbles, color shifts, and precipitates formed. This activity builds critical thinking as students collect qualitative data, draw conclusions about energy transfers occurring, and differentiate between physical changes and chemical reactions. Use this lab to reinforce chemistry concepts for middle schoolers or high schoolers in small groups or as an independent inquiry project.
