Candy Molecules Purpose To create fun, colorful, and delicious molecule structures out of candy, such as H20 and CO2 molecules Molecules are made up of at least two atoms in a definite arrangement and held together by a chemical bond. The science of molecules is known as molecular chemistry, dealing with the laws exercising control over the interaction between molecules that results in alteration of chemical bonds. Molecules may be made up of atoms in the same chemical element, such as Oxygen (O2) or water (H2O). Required materials Toothpicks Gum drop candy of various colors. The candy simply named "drops" works very well as their just the right size for the experiment. Bowl Estimated Experiment Time About 10 minutes or less. Step-By-Step Procedure 1. Assign each gum-drop candy to an atom based on color. For example, red = hydrogen, green = carbon, and yellow = oxygen. You may want to write down your atom to color assignments on paper so easily remember them. 2. Make a water molecule (the famous H2O). Water molecules are made up of two hydrogen atoms that are joined to one oxygen atom inside water. So, join two hydrogen (red) pieces of candy to one oxygen (yellow) piece of candy with toothpicks. Put your molecule into your bowl. Make several more H20 molecules and place them in the bowl. 3. Now make a carbon dioxide molecule (C02). Carbon dioxide molecules are made up of two oxygen atoms joined to one carbon atom. So, join two oxygen (yellow) pieces of candy to one carbon (green) piece of candy with the toothpicks. Make several more C02 molecules and place them in the bowl. 4. When you're ready, reach into the bowl and select a molecule. Can you identify it? After it's been identified, you can eat your molecule (be sure to remove the toothpicks first)! 5. Want to create more tasty molecules? See the following chart for examples of other molecules you can try to make! just and Idea you can try something like this .
