In the lab, you test and evaluate several different activities and determine if they produce chemical or physical changes. When two chemicals come in contact with one another and form a new compound, there is a chemical change, as shown by heat or light, a color change, or a new smell. When something undergoes a physical change, it remains the same chemically. It just has a different size, shape, or physical state. You will present ten different simple lab activities and ask the kids to evaluate them.
