Practical / DEMO

Practical

DEMO:

  • Skateboard x2
  • Fire Extinguisher (CO2)
  • 2 x Alcohol (Ethanol) Rocket PDF Risk
    • no bottle cap vs special bottle cap
  • Methane rocket PDF Risk


  • Alcohol first explain about the speed of exhaust- speed it up using a special nozzle. Then move onto methane rocket (hotter reaction)


Different Stations :

  • Balloon fire down a string
  • Two magnets repelling each other
  • Newtons cradel
  • A spring toy (jumps into air)
  • A boat in bowl of water - students push down and feel the force back)
  • Picture of fire extingusher (BELOW)
  • Picture of a gun (recoil)
  • Picture of a canoe


Safety

Safety procedures for methane and alcohol.

Warn students of loud noises

Studnets to stand behind the ignotion

Newton’s Third Law:

Whenever two objects interact, the forces they exert on each other are equal and opposite.

Students should be able to apply Newton’s Third Law to examples of equilibrium situations.
