We spent a lot of time playing with crystals (thanks to cousin Laura and her awesome crystal kit). Crystals gave us an opportunity to learn about solutions and saturation. We still have bit more to go on crystals, we will get back to it soon.
We also tried to make plastic out of milk. That was gross! It looked like cottage cheese and didn't smell great. But we were able to change milk into something completely different than milk.
This week we talked about blubber! Blubber is fat found on animals, mostly in the arctic. Beluga whales, polar bears, walrus', seals, penguins and narwhals all have some blubber.
Blubber is used to keep them warm. It works by adding an insulating layer which keeps heat in and keeps cold out. To demonstrate how this works we stuck our hands in some ice cold water. First we stuck our hands in by themselves. BRRRRR it was freezing! Anna had to take her hands immediately out. Then, we found ourselves some blubber. Using a plastic bag and some lard we made blubber gloves.
When we covered our hands with the gloves and put them in the water it wasn't cold anymore. If we made suits out of lard, we could go swimming with the polar bears.
Anna: Crystals were so cool, thanks god mother Laura! And the ice water was freezing!
Mina: The plastic was so gross!
Jack: The blubber kept us warm.
Science Fact: The Tyrannosaurus Rex has a smell center in its brain the size of an orange. Ours in comparison is as big as a pea.
