It’s a very simple lab experiment, but a good one. Place an M&M candy in a shallow dish of water and make your observations. I found this activity on the American Chemical Society website, Inquiry in Action. Students will see how the colored candy shell dissolves and creates a pattern in the water.
There are so many ways that this activity can be differentiated for students. It is an excellent lab for practicing the scientific method and can be used when discussing physical properties and physical changes.
The M&M Lab is also a great introductory lab for students to use when designing their own experiments. After completing this lab, students begin to think of additional experiments that could be tested:
- Does the temperature of the water affect the rate that the candy shell dissolves?
- Does a frozen candy produce the same results as a candy at room temperature?
- Does the color of the candy have an effect on the dissolving rate or pattern?
- What happens when other types of candy are placed in water?
Give your students the opportunity to perform the M&M Lab and see what experiments they can come up with.
