ScrewDriver Lab
1. His hand and the screwdriver are turning right.
2. It is slowly being pushed into the wooden block, and as it goes in, it tightens
3. His hand and the screwdriver are turning left
4. It is being pulled up and it is slowly loosening
5. When you are putting more pressure on the screw it sinks and tightens. When you put less pressure and pull, the screw rises.
Analysis - whenever there was less pressure the screw would loosen up and get pulled up, just like the warm wind in our atmosphere. Whenever there was more pressure the screw tightened and it got deeper in the hole, just like the cold wind in the atmosphere.
