Sarah Spivey’s Fun and Educational Demonstrations on GMSA@9 Excite Students about Science

Sarah’s Science Experiments with Dry Ice

Looking to get your students excited about science? Check out Sarah Spivey’s demonstrations on GMSA@9 every Wednesday. With the help of the San Antonio Zoo, Sarah will be breaking down complex scientific concepts in a fun and engaging way.

For those looking to conduct their own experiments at home, here are the materials you’ll need:

* Dry ice (remember to always handle with gloves)

* DRY ICE BIG BUBBLE: a large bowl, dish soap/water mixture, water, shoe lace or strip of cloth

* EXTINGUISHING CANDLE: tea light, match, Tupperware or small bowl

* DRY ICE “INSTRUMENT”: cups/containers of different sizes/shapes, water, soap

* BILLIONS OF BUBBLES: water, soap

Now that you have your materials ready let’s get started! Here are the step-by-step instructions for each experiment:

DRY ICE BIG BUBBLE:

1. Fill a large bowl with water and drop in a little dry ice.

2. 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.

EXTINGUISHING CANDLE:

1. Place a tea light inside of a Tupperware and light the candle.

2. Place some dry ice around the candle and watch as it slowly extinguishes.
