100 Days of Science #92-- Homemade Butter

I realized the other day that while I talked about making homemade butter several times in our homeschooling career we never actually took the time to make any!  My younger two boys vaguely remembered making butter when they were in pre-school but Ian never had.  

I quickly assembled our ingredients: a carton of heavy cream and a glass jar.  

Then I asked them HOW they think it works.  

Alec is my resident baker so he knows that if you whip heavy cream you'll get whipping cream.  He hypothesized that shaking it longer and harder would make the cream thicker until we ended up with butter.  

We filled our jar 1/2 way with cream and began shaking.  

My intent was to stop after a few minutes and see the actual whipping cream but my boy must have been shaking harder than I thought because in just a few minutes we could already see the butter and the butter cream (the milky stuff that's left over from making butter). 

I explained to the boys that the fat molecules in the heavy cream end up clumping together when shaken making up the butter and leaving behind the buttermilk.

  1. I bet this is so yummy. Would love to have some on an English muffin this morn. Have a great day

    1. I was thinking it would have been perfect with one of Alec's homemade English muffins.

  2. There is nothing like homemade butter. You do the coolest projects with your boys. :)
