Pendulums

Chemistry investigations:

  • Concentration and rate of reaction
  • Surface area and rate of reaction
  • Temperature and rate of reaction
  • Burning fuels (methanol, ethanol, propanol) – “Fuelling Up”
  • Bubble trouble

Biology investigations:

  • Pulse rate and exercise
  • How Weedy is that field? (From TKI)
