June Super Science Lab Report

Hello fellow scientist!  This month in Super Science Lab we did candy experiments.  We made the ‘M’ on the M&M’s float, saw the acids inside some candies, learned how to separate ingredients in chocolate, and even made a craft using only candy!   I think the highlight of the program was when we all made ice cream!   In case you missed it, here is the recipe to make your own homemade ice cream:


  • 1 tablespoon of sugar
  • ½ cup milk or half & half
  • ¼ teaspoon of vanilla (or cocoa/strawberries)
  • 6 tablespoons of rock salt
  • 1 pint-size plastic bag
  • 1 gallon-size plastic bag
  • Ice cubes

Experiment: Ice Cream in a Bag

1.       Fill the gallon-size bag half full of ice, and add the rock salt.  Seal the bag.

2.      Put milk, vanilla, and sugar into the pint-size bag, and seal it.

3.      Place the pint-size bag inside the gallon-size one, and seal it again carefully.

4.      Shake until the mixture is ice cream, which takes about 5 minutes.

5.      Wipe off the top of the small bag, then open it carefully.  Enjoy!

 How does it work?

Just like we use salt on icy roads in the winter, salt mixed with ice in this case also causes the ice to melt.  When salt comes into contact with ice, the freezing point of the ice is lowered.  Water will normally freeze at 32 degrees F.  A 10% salt solution freezes at 20 degrees F, and a 20% solution freezes at 2 degrees F. By lowering the temperature at which ice is frozen, we are able to create an environment in which the milk mixture can freeze at a temperature below 32 degrees F into ice cream.

I hope to see you next month.  We will be learning all about birds on July 23th at 1:30 pm.  Registration opens on July 9st at 9:00 am.  Please have your library card ready.
