by

Chemical Reaction exothermic

Your middle school science class is sure to love this engaging Exothermic Chemical Reaction Lab!

Students will see both a color change and an exothermic reaction with lots of bubbles and gas in this chemical reaction!

This is an easy-to-do science lab with clear directions and follow-up pages to reinforce ideas about chemical reactions, exothermic, acids and bases, and neutralization. Students will love this lab!

Materials Needed for this Exothermic Chemical Reaction:

  • Calcium chloride
  • Sodium Bicarbonate (Baking soda)
  • Cabbage water
  • Safety goggles
  • Gloves

This unit contains more than just one Exothermic Chemical Reaction Lab experiment!

This chemical reaction lab includes:

  • Lab directions
  • Lab pages
  • Safety Information
  • A reading page on Chemical vs Physical Changes
  • Follow-up Pages
  • Teacher Background Information
  • CER (Claim Evidence Reasoning)
  • Answer Keys

Other science teachers LOVE this Exothermic Chemical Reaction unit!

Check out the many perfect reviews on Teachers Pay Teachers.

My students just love the labs you put together. This one was great. Lots of bubbling and a temperature change. Really fun.

This is a standards-based unit helping you cover NGSS MS-PS1-2.

NGSSMS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride. Assessment is limited to analysis of the following properties: density, melting point, boiling point, solubility, flammability, and odor.

I am so impressed with this unit which manages to be distance learning and hands-on at the same time.  Really well thought out and engaging activities that allow students to practice each of the eight Science and Engineering Practices.  Really no prep for me!

The elephant article was excellent but I also thought the lab on dissecting a flower was broken down so easily, even telling me where to get inexpensive flowers!  This resource helped me teach this challenging standard in an engaging way.  Worth every penny!

My students loved this unit. I was able to present different elements of it throughout the month. It is hard to find interesting non-fictional, age-appropriate text for my students that they will enjoy. This was a great unit that aligned well for my students who have very different goals within the same group.
