Title – Making Slushies! Changes in Matter
By – Mina Bellia
Primary Subject – Science
Grade Level – K-3
- This lesson goes well when teaching children about the phases of matter, and how matter can change by taking away or adding heat.
- It is best to do this activity outdoors, and it’s lots of fun for the kids. A good way to incorporate some physical movement with science.
- Gallon ziploc bags, 1 per child
- Sandwich-size ziploc bags, 1 per child
- Bottle of Hawaiian Punch
- Rock Salt (used for making ice cream)
- Lots of ice!!
- Pour about 1/2 cup juice in each of the small ziploc bags. Zip them tight!
- 1. Each students gets a gallon-size bag.
- 2. Place the small bag of juice inside it.
- 3. Fill the large bag 3/4 full of ice.
- 4. Throw in a handful of rock salt.
- 5. Zip up the bag…and shake, shake, SHAKE!
- (It takes about 2 -3 minutes of shaking to get a good, thick slushie consistency.)
- I set up each supply they need at a different table (big bag, juice bag, ice, and rock salt & straws.) My class lined up and picked up each item as they walked by. I was at the ice station filling up their bags with ice.
- When you have made your slushie, take it out of the big bag and discard ice. Open slushie bag enough to get the straw in and drink it up!
- The kids really enjoy this activity, I highly recommend it.
- Make sure the juice bags are sealed good, otherwise rock salt may get into slushie, blah!
