This term we have been investigating AIR RESISTANCE.
We have learned that less air resistance can speed things up and more air resistance can slow things down.
We explore this with parachutes.
We discovered that: The larger the parachute, the longer it took to reach the ground!

We tried to make moving easier by pulling a box along different surfaces. We learned that friction can be reduced or increased. When two smooth surfaces rub against each other there is less friction and two rough surfaces create more friction.
