Let the temperature stabilize and then record the initial temperature of the peroxide. Step 2: Using the thermometer, measure the temperature of the peroxide. Step 1: Pour the hydrogen peroxide into your bowl. Steps to Performing this Simple Chemical Reaction Experiment Set all of the materials out on the table, but before starting the experiment ask your kids to make a guess as to what might happen.Īsk them to make a hypothesis and tell if they think a chemical reaction or a physical reaction will occur. For this experiment you need the following:
Now that you have given some background, it’s time to set up your experiment. Supplies for this Chemical Reaction Experiment They all got something out of it and all enjoyed it. If they observe any of these signs, a chemical reaction has taken place.įor reference I did this experiment with a 2 year old, a 4 year old, a 6 year old, and an 8 year old. Tell your kids that the main signs that a chemical reaction has occurred are: The molecules undergo a chemical change and are altered and can’t be returned to their original state. In a chemical reaction however, something new is made. Even mixing sugar and water is a physical change because you can get the sugar back out of the water through evaporation. Such as, you can melt ice into water by applying heat, but it is still H20 and can be formed back into ice.Ĭrushing a can, changes it’s physical shape but it is still a can. In a physical reaction the molecules undergo a physical change but they do not become something new. In this case you should have a discussion before completing the experiment about the difference between a chemical and physical reaction. So the first step of any science experiment, is to give some background information. Here is a simple experiment that shows a chemical reaction and produces heat!Ī Simple Chemical Reaction Experiment for Kids That Gives Off Heat! Simple chemistry experiments give young kids the chance to really think about what might occur and it gives them a chance to use the scientific method!
