This term we have 3 learning groups. They are learning about FLIGHT, SUBMARINES AND ELECTRICITY.
This week we did experiments to learn more about out topics.
The FLIGHT group looked at the forces a plane needs to fly. It need weight, lift, drag and thrust. We explored lift by blowing on a piece of paper like a wing would fly through the air. When we blew the paper lifted. We explored how thrusts worked by making a balloon rocket. We blew up a balloon and stuck it to a piece of straw on a string. The balloon flew on the string from the air pushing its way out of the balloon.
The SUBMARINE grouped looked into how a submarine can submerge and re-float. They used the internet to find an instructions on how to make their own submarine. They where able to see how a ballast tank helps a submarine submerge.
The ELECTRICITY group explored static electricity and what it does. They used the electricity to pick up tissues from the floor. The tissue jumped from the floor to the balloon. They also looked at whether two balloons were attracted to each other when a charged balloon was next to it.
