Gears, Levers and Pulleys.
We have been learning all about gears, levers and pulleys in our Science lessons. We created our own catapults - Catapults are just simple machines which use levers allowing a smaller force to have a greater effect. We then tested our catapult's throwing distance, power and accuracy!
We explored that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.
We considered what weight is, and how the impact caused by falling objects can vary, depending on their size, shape, mass and the height they fall from.
We identified and explained the effects of air resistance. We learnt how air resistance affects moving objects and planned an investigation to explore this further.
