Objective:To show that molecules consist of smaller molecules (or atoms) bound together and that those bonds contain energy that is released when the bonds are broken. |
Maybe put a photo here or Quicktime Movie of the demo |
Materials:Two wooden blocks, a heavy elastic band, scissors. |
|
Procedure:Take two wooden blocks (same or different sizes) and connect them by wrapping the elastic band around them. Explain that this represents two molecules (blocks) being held together by a chemical bond (elastic band).The blocks may have names or symbols, such as ADP and P printed on them. Using the scissors, cut the elastic. The elastic will fly away from the blocks, showing the release of energy. The blocks now represent the two separate molecules. |
