For our last science rotation we went to Room 16. We were learning about egg whites. Mrs Walker cracked an egg and poured the egg white into a big bowl.
It was a yellowish, runny liquid. We wanted to find out what would happen if we mixed it up.
We all had a turn using the beater.
There were lots of bubbles in it.
It changed from a yellowish colour to really white!
And it wasn't so runny anymore! Mrs Walker tried to tip it on Jessica but it didn't pour out! We learnt that the beater made lots of air bubbles and the egg white wrapped around the air to hold the bubbles.
Sophie is a big air bubble and Bella is the egg white wrapping around the bubble. After that, Mrs Walker used the egg white to make cookies.
In science this afternoon we went to Room 14. We looked at a photo of a corn field and talked about the history of popcorn. We learnt that corn kernels get cut off the corn cob and tossed around in a machine that heats them up. This dries them up and makes them really hard - this is popping corn!
We passed some popping corn around the class to look at it and feel it.
It felt really hard! We couldn't eat it because it would break our teeth! We put a small scoop of popping corn into a popcorn maker. The machine heated the corn which changed it. We could hear popping and popcorn starting coming out of the machine!
The hard, yellow kernels changed into soft, white popcorn that we could eat. The small scoop of popping corn made a whole bowl of popcorn!
