Learn from Steve how to perform a beautiful demonstration of how an antacid works. He puts a pH indicator solution into a beaker with a magnetic stirrer. He pours an acid in to show the red and a base to show the blue. Then he puts...

There's not much to this video. Steve Spangler and his twin sons visit 9 News and perform the classic chemical reaction between vinegar and baking soda to produce carbon dioxide gas. Where the value is in this video clip is that they set...

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...

Create disappearing ink and send your own secret messages. Have your learners explore the properties of acids and bases in order to figure out how to cause a chemical reaction. After they understand the process, they can perform some...

Steve Spangler shows how to make your own litmus paper. Using blackberries, construction paper, and water, learners can make their own litmus paper in the classroom. Then, they can take different liquids, such as oil and soapy water, and...

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...
