Action Reaction is a presentation centered on how the basics of chemical reactions can be applied to engineering. The basic principle of a chemical reaction being a rearrangement of atoms is explained using the formation of water molecules. Then, the five key signs of identifying chemical reactions are introduced with video demonstrations of each. For the hands on activity, the “elephant toothpaste” reaction is introduced. It is a safe reaction involving dilute hydrogen peroxide decomposing to air and water with an iodine catalyst. Doing this reaction in the presence of dish soap creates a column of foam. The students then preform this reaction, making a tall column of foam. Finally, presenters explain how reactions like this are used in all branches of engineering to help improve the world.
