Chemical Reaction Experiment With a Color Change

As a teacher, it is not that hard to find a chemical reaction for your students that will produce gas or even provide a change in temperature, but I wanted to show my students a dramatic color change as the result of a chemical reaction. This science experiment is so much fun and is a chemical reaction experiment with a color change that is dramatic! These reactants will change from white and red to bright yellow! This chemical reaction will also produce gas and the temperature will increase. It is an exothermic reaction.

Students will observe the three reactants and record their properties before they are combined and then students will combine these substances to observe the changes!

You will need sodium bicarbonate (baking soda), calcium chloride (the main ingredient in the road salt we use to device the roads), and Phenol red .02% aqueous solution. Phenol red is an indicator that will change colors under certain conditions.

Exothermic Reaction and Color Change

Three Labs in This Great Unit!

This amazing experiment changes from white and red, to bright fuchsia, to bright yellow! Students will be able to isolate the reactions and determine which combination is the exothermic reaction and which products are bases or acids.

In this lab, students will learn about the signs that a chemical reaction has occurred. They will learn about exothermic reactions, pH levels, and more! This resource has 5 days worth of activities and includes two labs. You will need sodium bicarbonate, calcium chloride, and Phenol red. These can be purchased at https://www.carolina.com/ You will also need containers (either a ziplock baggie or a jar).

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.

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!
