Simple Science Experiment for Kids- Freeze and Frost

Freeze and Frost

Isabella has been super obsessed with Frozen lately so this experiment was a little bit extra fun for her because she could pretend she had magic ice powers like Elsa.  Really she learned about freeze and frost by making some frost using ice cubes, salt, and a recycled metal coffee can! As Isabella says in her video, “Frost is the thin layer of ice that forms on grass, trees, cars, and other things when the weather turns cold.” Why do you think this happens? write down your answer in your Science Journal!

Simple Science Experiment for Kids- Freeze and Frost

What you will need:



Pens and Pencils,

Metal Coffee Can with plastic lid (empty, clean and dry, or a small stainless steel mixing bowl, plastic wrap, and a rubber band)

8-10 ice cubes

1/2 cup of salt


Result Timing: 30 minutes

What to do:

Draw a picture of your coffee can before you do anything, we drew a picture of our pitcher of ice as well. Put the ice cubes into the coffee can. Then pour the salt on top of the ice cubes, and then use the spoon to stir the salt and ice a few times. Put a lid on top of the container, or cover it tightly with plastic wrap and a rubber band. Let the can sit on a table or counter. Check back in 10 minutes then again in 20 minutes and 30 minutes do you see anything happening to the outside of the container?

Here is a sample of how you can form your chart:

Time:                                           Observations:

10 minutes                               Water appearing on the outside of the container.

20 minutes                              Frost beginning to form on the bottom of the can.

30 minutes                              Frost traveling up the can.

How it works

You should see the frost forming on the outside of the container starting at the bottom within about 10-20 minutes. This led Isabella to ask “If the ice cubes are on the inside of the container, why did frost form on the outside of the container?”

It is because of a process called condensation. Even when there’s not a cloud in the sky, there is water we can’t see called water vapor in the air around us. As the temperature cools, some of that invisible water vapor changes into liquid water that we can see and touch, In our experiment, the ice causes the sides of the container to become much cooler than the air around the container. This cooling caused the water vapor to change into the liquid water where it touched the container and then to freeze, forming a coating of frost.

Have you ever noticed how the outside of glass sometimes feels wet after you pour a very cold drink into it?

It’s not because the drink is leaking through the glass. Instead, since the drink makes the glass cooler than the air around, some of the water vapor in the air condenses turning into liquid water on the outside of the glass.
