Easy, Fun Experiment You Can Eat!

My first-grade daughter Mollie wanted a fun science experiment using candy, so we came up with the question "Which Chocolate Melts the Fastest?" This experiment can be used by older children if they do more research about why chocolate melts at different rates. For younger kids like Mollie, it is all right to let the experiment results be mostly based on what they observed and their ideas about why it happened that way.

We covered a lot of ground in her experiment, testing wrapped or unwrapped, different kinds of chocolate and also whether added ingredients made a difference. The choices we made were based on her own ideas and what we already had around the house. You could use just one of these variables in your experiment (such as wrapped and unwrapped, or different kinds of wrappers on the same chocolate). See some of the videos below for ideas.

Step One: Put groups of similar candies on a white paper towel.

Step 2: Put the candy groups about 2 inches away from a 60 watt light bulb.

Step 3: Test the candy every minute by touching it with my finger to see if it is melted. For trial 1, I used a variety of Hershey's small wrapped bars.

Trial 3: I used different kinds of Hershey's kisses and other smaller candies. (You don't have to do 3 trials but it gives you more candy to eat!)
