Watch the video of Sarah’s science experiment at Helotes Elementary School here! Hello parents, teachers, and students! Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it. Science with Sarah is in partnership with the San Antonio Zoo (Copyright KSAT 2023 – All rights reserved).

Here’s what you’ll need for the experiments:
– Dry ice (NEVER HANDLE DRY ICE WITHOUT GLOVES)
– DRY ICE BIG BUBBLE: 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

Do the experiments:
– DRY ICE BIG BUBBLE
Step 1: Fill a large bowl with water and drop a little dry ice in it
Step 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
Step 1: Place a tea light inside of a Tupperware and light the candle
Step 2: Place some dry ice around the candle and watch as it slowly extinguishes

– DRY ICE “INSTRUMENT”
Step 1: Place a small piece of dry ice on the table in front of you
Step 2: Using a spoon, press on the dry ice. It should make a silly sound

– BILLIONS OF BUBBLES
Step 1: Fill the containers with water and a little bit of soap
Step 2: Drop some dry ice into the containers and watch as lots and lots of bubbles form

If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT, fill out this form. “Winners” are selected at random. Copyright 2024 by KSAT – All rights reserved.
