How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of...

By watching this droll and delightful animation, physical scientists consider what happens when molecules collide. In this film, however, parodic people bump into each other, exchanging limbs in the process, just as molecules might trade...

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

A simple combination of baking soda and vinegar creates enough carbon dioxide to blow up a balloon! It's an awesome illustration of chemical reactions for upper elementary learners, or use it with slightly older scientists to introduce...

To understand the concept of stoichiometry, this class uses s'mores as an analogy. They compute the number of s'mores they can make based on the stoichiometric formula. Learners then apply this concept to how it is typically used in...

There's a lot going on here: air pressure changes, inertia, and chemical reactions. All of this occurs in 60 seconds time! As an end of the year physical science assessment, consider showing this video clip and then having learners write...

Create your own volcano using this recipe for fun. Using yeast, hydrogen peroxide and water, your class can make their own volcanoes. This is an easy way to illustrate this natural phenomenon as well as chemical reactions.

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.

It's amazing how much science can be taught with the use of eggs! Spangler gives a little "teaser" sample of some of the amazing demonstrations and experiments that can be done with them. In this one, he puts an egg in a glass of...

Photo reactive paper is used to do art! You can order this type of paper, have learners place objects on it, and then set it out in the sunlight for a few minutes to create a print. A chemical reaction occurs, driven by light, to turn...

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...

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...
