We had a great week in Science. As many of you know, I just started a 3rd grade position on Jan 2! Well, at our school we teach a nine week rotation of Science/Social Studies and then we switch to another homeroom and teach it again. I can't wait to get the whole way through 1 rotation.
I have the joy of teaching Physical Science, so we started this week with "What is Matter?" I really wanted to get their attention right away. What a better way than with a Science experiment!! Making butter!!! Showing a liquid to a solid.
small glass jars with very tight lids-I used baby food jars!!
Heavy Whipping Cream
Lots of arm movement!!
I pour heavy cream into the jars so they are halfway filled. This is key, because you want to incorporate some air into the shaking process. I have 4 groups of tables, each group got 1 jar and they shook it for about 1 minute and then I would have them switch.
10mins later (or so!!) We looked to see what was in each jar.....2 were whipped cream (less energy applied while shaking) 2 turned to butter (more energy applied while shaking) Kids loved this quick, easy and cheap experiment!!
