In Akeake we have been learning about floating and sinking. Mrs Wright did a really cool experiment with Rooms 8, 9 and 10. She had three cups filled with water, and three eggs. She put the first egg into the first cup and it sank to the bottom. In the next cup, she mixed 4 teaspoons of salt into the water and the egg floated. When she diluted (add more water to) the salty cup, the egg began to sink again. This led to a discussion about the Dead Sea and how people can float in the water because there is so much salt (it is dense).
We had the Christchurch Football Centre come in and teach us a bit about football. We got into teams with bibs and played a couple of games against each other. We really enjoyed the opportunity, and have already been asking about some basketball or hockey coaches that can teach us some new skills.
This week we had a visit from Science in a Van and lots of fun learning about science. The first session was an optical illusion that tricked our brains. We had to stare into the middle of a spinning circle for 10 seconds, then look at Allan's face and it looked like it was getting bigger and bigger! Then a teacher got up on stage and sat on a chair full of nails. We learnt that because there were so many nails, his weight was spread between them and so it didn't hurt. The main session was all about bubbles and how their behaviour is affected by what kind of gas is inside them, what mixture is used and how big the wand is. We learnt that dry ice is heavy and makes the bubbles fall on the ground, while helium is light and makes them float all the way up to the ceiling.
