Fun and Challenging EPRO8

In Te Ngahere the year six’s have been doing this Epro8 challenge. By this challenge we learnt there are 2 types of energy, Potential energy and Kinetic energy. 1. Potential energy- is when the object stays still. Ex ball, books and cup etc. 2. Kinetic energy- is when you move the object with something. Ex pen, pencil and ball etc. These two energy work together to move the things surrounding us. The first task we did was to build a catapult. We had 30 sticks, 30 rubber bands, one measuring tape, one scissor, one electric tape and a ping pong ball. We were three members in a group and the challenging part was how to share the ideas. We didn’t read the instructions properly and we ended up doing the first one wrong. We did not mark the spot where the ping pong ball landed. We immediately corrected it and got total 50 points. It was because then we worked it out with the right measurement. According to the second set of the instructions we were not supposed to untie the rubber bands from the sticks, although, we did it. Later, we realized that we could have made it stronger by reconstructing it. The best part I liked was that after the reconstruction we did the right measurement and got everything set right then we got are ive points back. With this I learnt that by doing the things on our own the things work in right direction. It reflects that every object in our surrounding moves with both, Potential energy and Kinetic energy. Have you ever made a catapult???? The Instruction of the EPRO8
