🧪 Sarah and Science: Dry Ice Experiment

👉 Watch a video of Sarah’s science experiments at Helotes Elementary School here.

Hello parents, teachers, and students!

Be sure to check out Wednesday’s GMSA@9 where meteorologist Sarah Spivey will demonstrate and explain the science behind it.

Here’s what you need

• Dry ice (never handle dry ice without gloves)

dry ice big bubble

• big bowl

• Dishwashing detergent and water mixture

• water

• shoelaces or strips of cloth

extinguish the candle

Let’s try an experiment

dry ice big bubble

• step 1: Fill a large bowl with water and add some dry ice.

• Step 2: Soak a shoelace or piece of cloth in soapy water, drag it over the bowl, and seal the bowl with soapy water. You should see large bubbles forming from the steam from the dry ice.

extinguish the candle

• step 1: Place a tea light inside the Tupperware and light the candle.

• Step 2: Place dry ice around the candle and watch it slowly disappear.

Dry ice “equipment”

• step 1: Place a small piece of dry ice on the table in front of you

• Step 2: Use a spoon to press the dry ice.It should make a stupid sound

billions of bubbles

step 1: Add water and a little soap to the container

Step 2: Drop some dry ice into the container and watch as lots of bubbles form.
