Forces

As part of our forces topic in Science, we have been learning about gravity, the effect of friction, air resistance, water resistance and also how gears, levers and pulleys allow a smaller force to have a greater effect.

We had 5 different stations this week and we explored and investigated each of the following areas:

  • Water Resistance – investigating how long different shapes of plasticine of the same mass took to sink
  • Friction – investigating how long different materials took to slide down a slope of different coverings took.
  • Gears – investigating how many turns different sized cogs made, and how these fit together to make objects move.
  • Pulleys – explored how pulleys help us to lift heavier objects more easily
  • Levers – exploring how can change the direction of a force or magnify it.
