4 Exciting Dry Ice Science Experiments for Kids
While it may seem difficult to get kids interested in learning about science, hands-on experiments are a great way to capture their interest. Dry ice experiments are an exciting way for kids to experience science first hand. Read on for four fun experiments to try out this weekend.
Dry Ice and Water
This is a classic dry ice experiment that kids still love every time. It’s also super easy, so it’s a good choice if you’re new to playing with dry ice. Take a chunk of dry ice and plop it in some warm water to create spooky “smoke,” which is just carbon dioxide sublimating from the dry ice. If you do this in a clear container, the kids can see the dry ice bubbling in the water and the “smoke” rising off the surface. It’s totally safe for them to touch the “smoke.”
Inflate a Balloon
Place a deflated balloon on the mouth of a bottle that has dry ice and water in it and watch as the balloon inflates on its own by the escaping carbon dioxide. Just remember to take the balloon off before it gets too full and pops. Once it is full, the kids have a great time batting it around. Blow up another balloon with your mouth so they can see the difference between the two gasses (the dry ice inflated balloon will be heavier). You could also blow a really big bubble in much the same way, which is super cool because you can see the “smoke” in it.
Put Out Fire
You can use dry ice to put out a fire and teach the science behind fire needing oxygen to burn. An adult should light a match and hold it in the carbon dioxide “smoke” that escapes from the dry ice in water. The fire will immediately go out because of the lack of oxygen.
Make some art with your dry ice. Add some dish soap to your dry ice in water, and your “smoke” will become buckets of bubbles billowing out of the top of the container. Next, add drops of food coloring on top of the bubbles and then dab with a sheet of paper. This step will produce a nice tie-dye type bubble print on the paper.
