I mentioned in our first marshmallow science experiment that we didn’t sort the marshmallows by color before adding them to the different liquids. At the end of that experiment the kids noticed that the water looked different, so we decided to try one more marshmallow science experiment during our marshmallow theme activities. In this rainbow marshmallow science experiment we investigated what happens to water after colored marshmallows are dissolved in it.

See it in Action
I guided the kids in setting up this experiment and encouraged them to tell me how we could find out the answer to our question. They decided how many marshmallows would go in each cup. Then they sorted the marshmallows by color and placed six marshmallows in each cup.
Next we talked about making predictions. I asked them to predict what color they thought the water in each cup would be after the marshmallows dissolved.
Both of the kids remembered from our first experiment that only the warm water made the marshmallows dissolve, so we added warm water to each cup. Like before they stirred and observed in their own styles. Him quiet and focused, her giving a play-by-play account of the process.
Once all of the marshmallows dissolved we sat and watched the water settle. Then we discussed our conclusions. They confirmed their original predictions, and they were proud little scientists!
Extend the learning by following this same science experiment procedure using Skittles. Then compare the results.
