Swimming pool investigations

There is a swimming pool next to my school, I thought it might be fun to think up some investigations that could be carried out there, here's a quick list:

  • Volume of a gas and depth.
  • Under water projectiles.
  • Analysis of the motion of sinking objects.
  • Analysis of the motion of buoyant objects.
  • The speed of waves at different depths.
  • Wave interference.
  • Wave amplitude and distance from a point source.
  • Centripetal force in the slide at different velocities.
  • Under water pendulums.
  • Inverted pendulums (?)

That'll do for now.
