How is science involved in this activity?

The salt mixed with the ice makes the melting temperature drop, which makes the ice take longer to unfreeze. The salt gives enough time for the ice to freeze the ice cream and have its characteristic texture. This allows us to shake the ice bag long enough to make the ice cream mixture solidify/freeze. If we are more salt the melting temperature will drop even more, and the ice cream mixture will take less time to freeze.

Teaching methodologies/activity outline

Step 1: Put the ice inside a big ziplock bag and crush it a little bit. (You will need quite a lot). Add the salt (generous amount).
Step 2: Squash a banana with a fork (in this case, half a banana) and mix it with milk (approximately ¼ of a cup). The quantities will change according to the amount of ice cream that wants to be made.
Step 3: You can add other ingredients to the mix and then pour the mix inside a tinier ziplock bag.
Step 4: Put the tiny bag inside the ice bag, make it fit so it has ice all around.
Step 5: Shake! The ice cream takes little time to be made (less than 5 minutes approximately), so be quick.
Step 6: Put the ice cream in a bowl, and now it’s time to enjoy.
