Today we built the Wind Turbine and learned a bit about wind energy and power. The kids loved it and some of them found a way to spin their wind turbines a little too fast. The topic for next week is an introduction to Pneumatics. Please ask the kids to clean up better as dropped parts were found today.
Today we built the sweeper and learned about gear combinations. The students compared it more to a weed whacker than a sweeper and liked playing around with it. The topic for next week is the Flywheel car. Please ask the kids to clean up and organise their kits a bit better as many pieces were found on the ground.
Did you watch how the sweeper do some cleaning? It is really a good example of gear combination. This class is to help us to understand what is:
- Driving Gear
- Driven Gear
How do the different sized gears affect the sweeper’s performance?
The class was run smoothly. Wesley made a good construction. The sweeper uses 2 same sized gears. Students found sweeping work performs different if the different gear combination is employed.
I really suggested our students to try the bigger driving gear + the smaller driven gear, it shows a powerful work.
