Science Week Fun - 6th Class make ice cream in a bag!

Science week got off to a tasty start in 6th class. It was cold, messy, and a lot of fun. We learned about freezing, states of matter, and how salt can lower the freezing point of ice — and the best part was, we got to eat our experiment at the end!

What We Needed:

  • 1 small resealable bag

  • 1 large resealable bag

  • 1 cup of milk

  • 1 cup of cream

  • 1 tablespoon of sugar

  • 1 teaspoon of vanilla essence

  • Ice cubes

  • 4 tablespoons of salt (rock salt or table salt) - we used both!

What We Did:

  1. We poured the milk, sugar, and vanilla into the small bag and sealed it tightly.

  2. Then we filled the big bag halfway with ice and added the salt.

  3. We placed the small bag inside the big one and sealed it up.

  4. After that, we shook it really hard for about 5 minutes — our hands got so cold!

  5. When we opened the bags, the liquid had turned into delicious, creamy ice cream

What We LEARNED:

We discovered that when salt is added to ice, it makes the ice melt more slowly and lowers its freezing point. That means the ice can get even colder than 0°C, which helps the milk mixture freeze into ice cream!
It was a perfect way to see science in action — and to have a tasty treat afterwards.
