Science with Sarah: Unleashing the Power of Dry Ice in Three Easy Experiments

Sarah’s Science Experiments with Dry Ice

“Science with Sarah” is a partnership between GMSA@9 and the San Antonio Zoo. Watch the video of Sarah’s science experiment at Helotes Elementary School here! Parents, teachers, and students, be sure to tune in to GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.

In this article, we will outline the materials you will need for each experiment and provide step-by-step instructions on how to perform them safely.

For the “DRY ICE BIG BUBBLE” experiment, you will need a large bowl, dish soap/water mixture, water, shoe lace or strip of cloth, and dry ice. To perform the experiment, fill a large bowl with water and drop a little dry ice in it. Dip a shoe lace or strip of cloth in a soapy solution and drag it across the bowl, sealing the bowl with soapy water. You should see a big bubble form with vapor from the dry ice.

The “EXTINGUISHING CANDLE” experiment requires a tea light, match, Tupperware or small bowl, and dry ice. Place a tea light inside of a Tupperware and light the candle. Place some dry ice around the candle and watch as it slowly extinguishes.

For the “DRY ICE “INSTRUMENT” experiment, place a small piece of dry ice on the table in front of you. Using a spoon, press on the dry ice
