Candy Heart Sink the Boat Science Activity

To begin the candy heart sink the boat activity, simply start filling the container one heart at a time. Encourage your child to count as he fills up his heart. You can even keep track on paper how many hearts it takes to fill up each “boat” before it sinks. We found out that it was a different amount each time! We also saw that the placement of the candy hearts made a difference. We tested what would happen if we filled just one part of the “boat” making it uneven. The “boat” sank faster! He thought this was pretty neat. We explored concepts like balanced and unbalanced, even and uneven, and sink and float! Great math and science ideas for young kids to learn about.

We also observed something else neat happening once our boats hand completely sunk, the candies started to dissolve! We left our candy heart sink the boat activity out on the table to see what would happen over time. He said the candy hearts would disappear. A couple hours later, after a swim lesson, this is what we found. What was left of the hearts were floating and most had dissolved quite a bit. He tried to pick one up and it just squished in his finger tips.
