While at the grocery store, I saw Valentine’s Day inspired peep marshmallows. They had fun flavored heart ones. I quickly had 2 ideas for them. None of which included eating them, lol. Doing a marshmallow experiment was one of them. We love to see what happens to sugar stuff / candy when we place it in water. Simple science that is hands on for my young kids is always a hit. I love that while they think they are playing they are learning too. What happens to a marshmallow in water? Why does it do that?
Marshmallow Experiment for Kids
What we used:
peep marshmallows- vanilla creme
3 small glasses- a clear cup is good for observing. Clear beakers or clear plastic cups would work too.
clear soda- we had Sprite
a fun tray too
What we did:
Let the kids fill one glass with hot water, one glass with cold water, and one glass with Sprite. Now let them place one marshmallow in each glass. After they place the marshmallows in the glasses let them watch to see if they notice anything different. Ask them questions and let them ask questions. Big brother started making comments on what he saw. The sugar is melting, the marshmallow is growing…
What can we learn:
The kids observed that the hot water melted the sugar sprinkles off the marshmallow. The one with the soda puffed up and the cold water one “looked sticky” per big brother.
Why marshmallows float:
We often start science experiments with a simple question “Will it sink or float”? Marshmallows have tiny air bubbles in them making them less dense than water. Because marshmallows are less dense than water they float. The Marshmallow Experiment is a simple way to introduce young kids to density.
