We were lucky enough to join with the rest of Tasman syndicate and participate in an immersion science rotation where we carried out experiments in each class. We made hokey pokey, melted chocolate, dissolved the shell from an egg and made a cloud in a bottle.
Here are some photos from all of our science fun.
Our cloud in a bottle experiment
When we added pressure to isopropyl and then released the pressure it formed a cloud in a bottle.
Seeing gas turn into a liquid through condensation
The Eggciting Eggsperiment
We were able to dissolve the shell on an egg using vinegar, the acetic acid in the vinegar reacted with the calcium in the shell which caused the shell to dissolve but left the membrane intact.
Home made hokey pokey
Our hokey pokey did't quite turn out the way we had hoped, it was a little bit sticky because we didn't want it to burn, luckily Mrs Miller felt sorry for us and our runny hokey pokey, so she made us some at home. It was very sweet!
Oobleck
Oobleck is sticky, messy and a whole lot of fun. Oobleck, or quicksand as it is better known is a funny material because it is both a liquid and a solid. When pressure is applied it becomes a solid but if you touch it softly it is a liquid.
Can you pick up a piece of ice with a piece of string and some salt?
the answer is yes, but not if Miss Nisbet tips too much salt on the ice and makes it sink. We learnt that when you put a thin later of salt over the top of a piece of string, the salt melts just the top layer of the ice which the makes the ice stick to the string, just enough to lift it up.
