Welcome to 31 days of STEM activities for kids! Each day, we will be posting a fun post about STEM topics (science, technology, engineering, and math). We will have just about 10 posts per topic starting with science.
Today is our first science project for kids- making butter!
The Science Behind Making Butter
When cream is shaken, the fat molecules in the cream leave their normal position and clump together. After a while, all of the fat molecules cling together, forming a lump of butter and leaving the buttermilk behind.
Making butter is a perfect science experiment for kids of all ages. Monkey loved watching the fat separate, and even Bo enjoyed shaking up the cream. As long as you have cream at home, this project requires no special ingredients or supplies.
How to Make Butter from Cream
- Heavy whipping cream
- Mason jar
- A willing shaker
Fill your mason jar about half way with cream.
Take turns shaking the butter until it is agitated and the fat begins to clump. We found that it took just a few minutes for the fat to start to clump together. At this stage, the butter looked almost like ice cream with a slightly sandy texture.
After we got tired of shaking the cream, we rolled it up and down the floor for a while before starting to shake it again.
After about 10 minutes of shaking/rolling, the cream was converted into butter. This happened quite suddenly, and much faster than we thought. It only took about one minute of shaking before the cream turned into whipped cream. This method even seemed faster than when you whip cream with a stand mixer.
Monkey rinsed away the buttermilk and added salt to the butter. We ate it over the next few days and it was delicious!
We also tried the buttermilk, but we decided it was not good at all. It tasted like water with a tiny bit of milk added. Not so good. It was nothing like the buttermilk sold in grocery stores.
Have you made butter? Of all the science experiments we tried this month, making butter was one of our favorites!
