Kids love hands on science experiments because it makes learning so much fun. And what’s better than a science experiment that you can eat?! Try making homemade butter with your kids…they will be amazed as a liquid magically turn into a solid and will love tasting it when it’s all done!

How do you make homemade butter?

Supplies:

  • heavy whipping cream
  • a glass jar

Step 1: Fill a glass jar half way with heavy cream. It’s important to leave space in the jar to shake the cream.

Step 2: Screw the lid onto the jar. (Make sure it’s on tight!) Shake the jar, and continue to shake until it forms into butter! The amount of time it takes will depend on how hard and fast you are shaking it. You will probably end up taking over for your kids at some point. Here are the different phases:

Keep shaking it until the butter turns into a solid ball. The leftover liquid is buttermilk.

Be sure to open the jar at various times to show your kids exactly what’s happening.

Step 3: Remove the butter from the jar and add it to a bowl of water. Massage it to get out the excess buttermilk (this will help the butter to keep longer). By the way, this step is an awesome sensory activity for your kids! But, you can opt for gloves if you’d rather avoid the mess.

What is the science behind how butter is made?

Cream goes through a physical change when it becomes butter. When the cream is shaken, the fat molecules get shaken out of position and join with other fat molecules, which forms the butter.
