Today we had a visit from Oscar and Micheal. They came to help us understand potential and kinetic energy. This will help us work out how we will get the water to move once we collect it.
We did an experiment with balloons moving across the string – The balloons were different sizes so we had to come up with a hypothesis of which would get to the end first. There were mixed views so then we put it to the test. Our first one didn’t work as the straw got caught so we had to adapt the setup. Then we had a wide variety of results due to different variables – now we understand why you have to do more than one test. You need to collect lots of data to make an informed decision.
