The last day of our Simple Machines unit was probably our favorite. We spent hours and hours making and toying with different ways of making pulleys and wheel-n-axles!
We started (as always) by reading a couple of books. We did an activity to show investigate which way of looping the rope made it easier/harder to pull the broom-handles together:
The kids really enjoyed Pull, Lift, and Lower: A Book About Pulleys (Amazing Science: Simple Machines). (affiliate link)
ED and I went off to the kitchen to do one of the activities suggested in the book. We created a clothes-line type pulley:
Meanwhile, DD and LD got no help at all from me. I just dumped a whole lot of materials on the carpet in front of them and told them they had 30 minutes to bring me a pulley that really worked. They were SO excited and set to work immediately!
LD came running into the kitchen to show me what he had come up with:
Meanwhile, DD had taken her pulley contraption outside and was attaching it to the banister:
Meanwhile, ED wanted to create another pulley system so she (and I) put together movable cups:
Meanwhile, LD was so inspired by DD’s idea to go outside that he modified his pulley system and attached it to the bridge banister so he could load supplies to bring up to his room:
The other two quickly joined in — and duct-tape quickly ruled the day as they attempted to attach their pulleys to the banister:
The kids also made a couple of wheel-and-axle contraptions…
But over all it was the pulleys that totally engaged them for the afternoon. They spent over two hours working on and tinkering with their pulleys! It was SUCH a satisfying day for them!
Anyway, that just about brings our unit to a close. Don’t forget that you can download the Simple Machine Packet that I made for my kids. Just follow the link below:
