Make a Halloween pumpkin foam at the mouth! Using hydrogen peroxide, toothpaste, and yeast, you can recreate this chemical reaction in your classroom. It can lead to a discussion of the way ingredients mix together to make a new...

Chemical reactions can be beautiful. Show your learners how to make a crystal tree using cardboard, food coloring, Mrs. Stuart's Bluing, ammonia, and salt. Use this activity to demonstrate crystal growth within Earth. The results are...

The light sticks that trick-or-treaters carry at Halloween glow by the process of chemiluminescence, a chemical reaction in which electrons jump to a higher energy level. In this video, the variable of temperature is introduced to find...

Have your class write secret messages using Goldenrod paper and a basic liquid such as ammonia. This is a great way to illustrate the chemical reactions between acids and bases. This could lead to an exploration of chemical reactions and...

An exothermic reaction is demonstrated by showing what happens when hydrogen peroxide reacts with manganese dioxide. It creates the effect used by film makers to have a genie coming out of a bottle in a burst of cloudy gas. Spangler is...

A film canister, Alka Seltzer, and a little water can be an explosive combination. Have your learners try out this chemical reaction in the classroom, and then discuss the results.

In honor of the 4th of July, Steve Spangler shows how to make an explosive concoction in red, white, and blue. Using hydrogen peroxide, dishwashing liquid, and yeast, he creates a colorful chemical reaction. Consider this combination...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

Make your own crystals. Learners can use borax, water, food coloring, and a string to make a colorful crystal. This is a great way to explore chemical reactions, crystal formation, or evaporation.

Are you looking for a resource that will yield great results? Scholars view a video in the JFR Science playlist that shows the method for computing percent yield. It highlights the equation and explains how to find each component.

Young chemists examine the effects of salt on the pH levels of solutions with the help of this instructional video. Taking a close look at reactions between three different salts and water, students learn to predict the...

An understanding of chemical reactions really boils down to two concepts: entropy and enthalpy. Follow along with this instructional video as it explains how these two principles are used to calculate Gibbs free-energy which...

In honor of the 4th of July, Steve Spangler shows how to make an explosive concoction in red, white, and blue. Using hydrogen peroxide, dishwashing liquid, and yeast, he creates a colorful chemical reaction. Consider this combination...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

A great video demonstration along with teaching notes that shows the release of energy and resulting byproducts when a gummy bear is oxidized when heated with potassium chlorate.

The aim of this lesson is to introduce the concept of Neutralization and its application in our daily lives. Students are encouraged to construct their knowledge of Neutralization through brainstorming sessions, experiments, and mind...
