After our visit to the Planetarium we continued on learning about gravity.  We designed and made our own parachutes using tin foil and kitchen paper in order to slow down the speed at which plasticine fell to the ground.  We also had fun making paper helicopters and watching what happened when we changed the length of the rotors, the size of the actual paper helicopter and changed the weight attached to the helicopter.  We were fascinated that the helicopter rotated the opposite direction when we changed the direction of the rotors!!
