In the Unstoppables, we are doing a lot of practical, hands on science experiments! We have been learning about kitchen chemistry, the scientific method and how to record experiments using a list of instructions.
Room Two recently made sherbet, and found out about how acids, bases and the mouth's saliva create carbon dioxide bubbles. From the look on the kids faces some of the taste testing had interesting results!
Room Three found out that when you mix milk and vinegar, the casein in the milk seperates. This is a plastic substance which they have formed into cubes. These cubes are drying on their window sill and will be used to make dice! Room Four did the same experiment and are making bouncy balls.

Room Four made butter yesterday. You can read all about it on their blog page here. It was delicious!

| Yum! |
Room Five inflated balloons today with carbon dioxide. They added baking soda to a bottle of vinegar. This created a chemical reaction which made carbon dioxide. This bubbled up and inflated the balloon.

Make sure you check out the blog next week to see what happens when we make oobleck, film canister rockets and ini
Room 12 says: We made some glue and we'd like to share it with you. We used flour and water. We mixed it together. It was all gooey. We stuck newspaper shapes together and it was fun!
ReplyDeleteWe'd love to hear more about your kitchen chemistry and maybe even taste test it (if it's safe!)
We'd love it if you wrote back...
Hi Room 12. It is Mr B here from Room Four. Today we are making something called OOBLECK, and we would love to come and show you it this afternoon. Then you could show us your glue too. You don't want to eat OOBLECK though! Next week we are making hokey pokey, so we can bring you some to try next Thursday!
