Lesson Plan

Temperature Changes in Dissolving

Curated and Reviewed by Lesson Planet

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own experiments to determine if specific reactions were endothermic or exothermic.
