In this post I will be explaining how to make sorbet from apple juice! This is a fun way to show your kids how reversible change works, and your kids get a yummy treat as a reward. So, let’s get started!
Here is what you’ll need for this experiment:
½ cup of apple juice, 1 cup of salt, 1 cup of water, 2 cups of ice, 1 small ziploc, and 1 gallon sized ziploc.
First, pour the apple juice into the small ziploc and seal it. In the gallon sized ziploc, put in the water, salt, and ice.
Then, stir up the salted water to help the salt dissolve better. The salt lowers the freezing point of the water! If the salt does not mix all the way, that is okay, I had a lot of salt that did not dissolve but the experiment still worked!
Now, place the sealed apple juice bag inside the salted ice water bag. Seal the gallon sized bag and start shaking it around! Shake the bag for 3 to 5 minutes. I found that shaking it side to side was more effective than trying to shake it up and down! As you shake the bag around, the apple juice is starting to freeze.
After shaking it up, open the gallon sized ziploc and take out the apple juice bag. Wow! Now you have an apple sorbet!
The juice started out as a liquid, and then was transformed into a solid! But, if you leave the apple sorbet on the counter, it will return to it’s liquid form. Reversible change is change that can be undone. So, since we went from a liquid to a solid, and then back to a liquid, we have done reversible change! And, we have a yummy snack.
Through this experiment, your kids can understand how reversible change works in a simple way! Check us out on TikTok and Instagram for more content, and check out our other blog posts posted on stemchef.com for more fun food based experiments!
