Melting Hearts

What you’ll need:

Tray of ice cubes,
Bowl of colored water,
A small amount of salt,
Extra bowls for pouring and transferring,
Small spoon
And an eye dropper.

For the ice cubes, I chose heart shaped for Valentines Day and I colored the water red.
The purpose of this activity is to compare ways of trying to melt the hearts. Will the water, salt or water and salt together melt the hearts faster?
Another thing about this activity is it’s great for fine motor skills while scooping and squeezing the eye dropper.

On the top left, there are the ice cubes. Next to them is the red water. On the bottom left, there is the salt, and then the empty bowl that the salt can be transferred too and finally on the bottom right corner, there is the other empty bowl for the red water. The water is transferred with the eye dropper and the small spoon is used for the salt. The kids can take apart the ice by themselves. That is one of the things I like about silicone trays is the ice is easy to take out because it doesn’t stick.

What happens when red water is added to the hearts?

What happens when salt is added to the hearts?

Finally, what happens when you combine everything?

  1. What a great science lesson! Thanks for sharing this one. I had picked up the heart ice cube trays at Target in the dollar section knowing I could find a cool activity to do with them. Thanks for sharing.
