Air Resistance

Today Room 9 went outside and experienced the effect of air resistance.
We began by walking and then running. We then experimented with material of larger surface area to see what effect that had had we ran over a set distance.

Tomorrow we will share our thoughts and our reasons as to what forces were in play. Today we are sharing some photos.

But, here is a question to ponder: Why, when you move forward does the sheet / tarp / parachute form into a convex shape ( a bulge in the middle)? There is a scientific explanation for this - it's based around high and low pressure, fast and slow air flow.
