🧪 Science with Sarah: Dry ice experiments

👉 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.

HERE’S WHAT YOU’LL NEED

• 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”

• Metal spoon

BILLIONS OF BUBBLES

• Cups/containers of different sizes/shapes
• 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
