Demo of Physics Ideas
I am in a slow process of collecting some materials for the Five DIY physics demos from Symmetry Magazine. So far I have:-
- String
- Rubber Balls
- Small metal ball bearings
- Rubber Sheet
- Ping pong balls
With a 30cm x 30cm sheet of 1mm thick rubber. This can be used to demonstrate space and a ball or other object placed on this will bend the sheet around it.
The image from Open Clip art – sort of illustrates this in terms of a black hole.
This makes sense if you understand the physics, just hard to explain here.
I need some tennis balls, but I can pick them up easy enough. Hopefully I can do some of this at the next STEM group meeting, if not it is something that can be undertaken in a school, where I can get help from teachers & technicians. I don't think a TA is expected to do the whole demo :)
I am not sure if I can get hold of iron sand easily, but a school can though.
