Kia Ora!
The senior school has been working on an engineering project about engineering, We had to be in a team and chose what kind of engineer we were going to talk about, our group picked electricl engineering. and our team built two models – a wind turbine and a paper circuit. It was exciting to test out our ideas and see how they worked in real life.
For our first model, we created a paper circuit. We used copper tape, a coin shaped battery, and a LED lights. By connecting the copper tape properly, we made the led light up. Doing this helped us understand how electricity flows through a circuit, and how even small mistakes, like gaps in the tape, can stop it from working.
Our second model was a wind turbine. At first, we tried cutting wooden sticks into blade shapes, but they didn’t spin properly. Then, we had the idea of adding cardboard to the blades, which made them bigger and lighter. This actually worked! The blades started spinning when we blew on them or used a fan. It showed us how turbines can catch wind and turn it into power. We used a PCB (piece of cardboard) which was connected to the wind turbine and our biggest task was to light up all the led lights.
Our wind turbine had a bit of bad luck it broke during testing but the cool part is that it still managed to spin and generate power and light up some of the led lights! That showed us how strong the design was, even when things didn’t go perfectly. Our paper circuit had the opposite problem. At first, it worked nicely with the lights switching on, but later it stopped working. Even though that was a little disappointing, it gave us a good reminder that circuits need to be carefully connected and tested again and again.
The best part of it all was our presentation. We explained our work clearly, answered questions, and showed confidence. We also had a fun theme – everything matched in blue and purple, which made our display stand out. Overall, even with things breaking down, we felt proud of what we made and how much we learned about problem-solving in electrical engineering. The amount of people that can be in a group is around 3/4 and we had 4 people me tashifa aisha and sharlet. I think we did a good job working together as a group.
