In science we have been learning all about forces. For the first two weeks we learned about gravity and air resistance. We made our own paper helicopters and investigated if big ones or small ones would hit the floor first. We also investigated how to make the helicopters fall faster and how to change the direction they were rotating.
We set ourselves a challenge to see which group could design and make a parachute that would stay in the air for the longest. Each group got a plastic bag, scissors, sellotape, string and a Lego man.
