First, blow up a balloon with regular air, tie it off, and set it aside.
It’s that time of year again! Kids are back to school and ready for a new year of learning! With this in mind, we wanted to offer teachers, parents, and students a fun, educational experiment using dry ice that can be done in the classroom or at home.
What You Do
Before you get started with your experiment, make sure you’re either in a well-ventilated room or outside and that an adult is present. Because carbon dioxide (CO2) is heavier than air (which is what you’re trying to prove – safely) it displaces oxygen and, therefore, presents a suffocation hazard. You can also read about the best Safe Handling of Dry Ice practices here to make sure all proper precautions are taken before and during your experiment.
This is because carbon dioxide is heavier than air and you’ve just seen it with your own eyes!
Now that you have two inflated balloons – one filled with normal air, one filled with carbon dioxide – designate two children to each hold a balloon. Then, instruct them – on the count of three – to toss the balloons and watch as the balloon filled with carbon dioxide falls more quickly to the ground than the balloon filled with air.
This experiment will show how carbon dioxide (CO2) is heavier than air – with balloons! What kid doesn’t love balloons? So what better way to help them learn about different gases and their weight than to use a fun, hands-on experiment to show them?
