-
Exothermic & Endothermic, Chemical Change, Heat, Temperature, Classification of Reactions | Middle School, High School
Lab: Designing Exothermic and Endothermic Reactions
In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.
-
Cracking, Chemical Change | High School
Demonstration: Cracking Reaction
In this demo, students will witness a cracking reaction. They will verify the products by exposing the products to three side reactions.
