Turning cream into...

 We have been learning a little about fats. We need to eat them to keep our body healthy, and our body stores them.  We discussed how scientists are reconsidering how much fat is bad for us, and comparing it with questioning how much sugar is bad for us. We learned how oil is the name for a liquid fat.

We practiced using our thinking as scientists ideas: predict, observe and explain; by predicting what would happen to cream if it was shaken hard. We took turns shaking it and stopped it every minute to observe what changes had happened. Within four minutes of very vigorous shaking it had turned into cream and buttermilk!

Some of us had predicted this and others were surprised. The fat molecules in the cream stuck together and the product was cream, leaving some buttermilk left over.

Those of us who wanted to had a taste - it was pretty good!

Have a look at this video to see a Russian fairy tale about this, and the value of persevering, one of the character strengths we're learning about.

  1. Thank you for sharing this. I like your "thinking as scientist" ideas. I love the Tale of Two Frogs. I will share this with Tautoru kids. Nicola
