Exothermic and Endothermic Reactions – Middle School Science Unit

Endothermic and Exothermic Reactions

Do you need a little help covering exothermic and endothermic reactions in your 6th, 7th, or 8th grade science class?

This complete unit will help you cover standard NGSS MS PS1-6, will save you lots of time and energy, and will keep your students engaged!

Students will learn about exothermic and endothermic reactions in dramatic experiments in which they see the temperature quickly rise or drop. They will use this information to design a cold pack. Students will use engineering skills to engage in the design cycle and they will construct a solution.

Undertake a design project, engaging in the design cycle, to construct and/or implement a solution that meets specific design criteria and constraints test, and modify a device that either releases or absorbs thermal energy by chemical processes.


This resource includes an informative slide show, strategic note-taking guide, two lab activities, a STEM engineering activity, a reading passage, response pages, a quiz, and answer keys for everything!

Check out two of the dozens of perfect reviews:

Wow! What a great unit with interesting labs…my students loved seeing the temperature drop or rise right before their eyes! Great STEM engineering integration. The students use the science and engineering practices and really came up with some great prototypes. Loved this whole unit. Really well designed.
