This Investigating the Line lesson plan also includes:
Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now they compare two different-colored drops of corn syrup to see if they mix or behave in the same way as the candy coats. This pair of activities is not essential to the unit on dissolving, but they do serve as an engaging enrichment.
