In Te Ngahere on Tuesday when the year 7 & 8’s went to technology. While the year six’s were at school we did an EPro8 Challenge. The first challenge we were trying to do was Castle Siege. We had to build a protection system for the king because he was under attack. My group is Te Hauata and Manaaki. We used Bamboo sticks, rubber bands, paper, tape and a ping pong ball to build the catapult. When we were doing the EPro8 challenge we learnt about two types of energy, they were called Potential energy and Kinetic energy. We learnt that Potential energy is were all the energy stores up in the ball and the Kinetic energy moves and pushes all the energy that the potential energy stored. For example: when you are playing bowling and you use potential energy when you are storing all the energy and then you use Kinetic energy it pushes the bowling ball. Also the bowling ball is really stiff but when you use Potential energy and store all the energy then you use Kinetic energy the bowling ball will move and roll. The Kinetic energy worked really well because the Potential energy stores all the energy for the Kinetic energy so that the ball can roll. When we were testing our catapult we didn’t finish it in time to be checked by the judge(Whaea Becks). What my group and I found challenging was when we were trying all of our ideas but it still keeps on breaking or not working we got really upset and we were in the pit. Then when Gina came along and talked to us. Then Gina starting talking to us we kept on building and coming up with ideas and then we got somewhere. This made us very happy. What I thought my group and I did well was that we had a lot of ideas that we all came up with and we worked as a team. Next time we do work in a group I will try and work faster with my group and keep on talking to come up with more ideas.
Did you already know what Potential and Kinetic Energy is?
