Frost On A Can Winter Experiment

We can show you how to make it frosty inside, even when it’s not outside! Whether you have freezing cold temperatures keeping you inside or too hot temperatures outside, you can still enjoy some simple winter science. Learn how to make frost on a can for an easy winter science experiment you can share with the kids!

WINTER FROST EXPERIMENT

Although we live in a wintery climate, we either have cold temperatures keeping us indoors or a blizzard! I can handle only so much screen time as a parent, so it’s great to have simple science activities on hand to pass the time. Make sure to check out our winter snowstorm in a jar too!

This is another easy-to-set-up winter science experiment that pulls from what you have around the house. We love science that can be set up in minutes and is hands-on for the kids.

My goal is to have you feel comfortable with enjoying science at home. Learn how easy it is to set up science at home with your kids or find fun new ideas to bring into the classroom.

MORE ICE EXPERIMENTS TO TRY

January is a fantastic time to explore all kinds of winter theme science. I will say that frost formation on a can indoors is quite exciting for kiddos. There’s plenty more fun to be had with ice cubes and ice this winter, including homemade ice cream!

HOW TO MAKE FROST IN A CAN SCIENCE EXPERIMENT

It’s time to create your own frost science experiment! You might need to go to the recycling container for this one. Or if you are like me, you will need to cook something first to get a can ready. Make sure there are no sharp edges on your can!

Let’s get started learning how to make frost on a can! It’s COOL science in all word meanings, but it’s also quick and fun for kids.

Make sure to print out our Winter STEM Challenge Cards, too!

YOU WILL NEED:

• Ice cubes (crushed if possible)
• Salt (rock salt or coarse salt if possible)
• Metal can with the label removed

INSTRUCTIONS

Again, whether you have recently enjoyed a can of soup or beans, make sure the edges of the can are kid-safe and friendly for little fingers. Also, save the lid! Work gloves and safety glasses are never a bad thing to have on hand for kids.

STEP 1. You will want to fill the can with ice.

STEP 2. Add a layer of salt and cover the contents with the can’s lid.

STEP 3. Then all you need to do is shake the ice and salt mixture! Be somewhat careful, so the contents don’t spill everywhere.

CHEMICAL REACTION

Mixing creates a salt solution. This salt solution causes the freezing point of ice to drop and allows the ice to melt. When the salt mixture gets below 32 degrees, the water vapor around the can begins to freeze and form frost!

Watch the frost form on the outside of the can. It can take up to 10 minutes! You should start to see some changes on the surface of the jar or can after about 3 minutes.

Scroll down to read a bit of simple science behind the real effect of creating a thin layer of crystals or frost on the outside of the metal can.

Shake up the ice and salt and keep a look out for the frost forming on the outside of the can.

HOW DO YOU GET FROST ON THE OUTSIDE OF THE CAN?

First, what is frost? Frost is a thin layer of ice crystals that forms on a solid surface. Go outside on a cold winter morning, and you might see frost on things like your car, windows, grass, and other plants. 

But how do you end up with frost on the outside of the can when you are indoors?  Putting ice inside the can makes the metal can very cold.

Adding salt to the ice melts the ice and lowers the temperature of that ice water to below freezing point. Learn more about salt and ice with our what makes ice melt faster experiment! That means the metal can get even colder!

Next, water vapor in the air (water in its gas form) comes in contact with the metal can, whose temperature is below freezing now. This results in a phase change from water vapor to ice as the water vapor reaches freezing. This is also called the dew point. Voila, frost has formed!

It’s easy to experiment with winter science inside. Even if you live among palm trees, there are always new things to learn and discover!
