In this lab students measure the temperature change during two chemical reactions - one exothermic, and one endothermic.
Students investigate the relationship between heat flow and temperature and complete "fill in the blank" style worksheets as they progress through the lab. The end result is a complete lab report following the scientific method.
This lesson is self-contained and the experiment does not require any additional planning on the teacher's part.
