Room 5 have been experimenting with pulleys. We were challenged to lift a toy car within a shoe box using a pulley. The car had to travel at least halfway up the box. Here are some of our observations about pulleys
- Pulleys help us to lift heavy objects with little effort
- The pulley makes the weight of the object being lifted seem lighter
- Pulleys are found all around us e.g. raising the flag, automatic garage door, elevators and on cranes
This looks like a really fun activity!
ReplyDeleteNice work Room 5, I wonder if that's the same concept which applies for the lifts in the buildings....
