Forces


We have been exploring air resistance and water resistance in Science.
We made parachutes and tested the speed at which they fall when they have various number of holes in them.
This was followed by designing a superhero submarine! We found that the pointier the front of the submarine, the more streamline it was. as a result it encountered less resistance and travelled faster!
