Pressures On The Earth

Yesterday my class had a quiz on our inquiry topic sustainability, unlucky for me I wasn't there but here a quick recap on what we did.We had to have a balloon and we had been asked a question and if when didn't have a sustainable question we had to blow air to show that we were pressuring the earth by blowing into the balloon.If you look at Harry's balloon it had popped because of his answers he destroyed the earth!! Heres the pic collage and it shows the after for my table group.
