Hello this is my choice day reflection
The activities we could participate were bottle rockets, knitting, SimCity, countdown, flight school, mosaic madness, long division, garden making, acting out and sewcializing.
The activity I was put in to was countdown. In this activity we had several materials such as icy pole sticks, 1 meter of tape, rubber bands, milk lids, paper and glue. With these materials we had to create a device to fling a table tennis ball accurately into a container from different points. At first I tried to create a sort of catapult but after trying extensively to create something I decided to create a simpler design. I thought one of the most simple designs to make would be a slingshot so I attempted that. I used icy pole sticks to make the frame and a rubber band glued in the right position to propel the ball when it was pulled back and released. This design worked alight but it was not consistent or accurate. To fix that problem I had with accuracy I created a funnel with paper to straiten the line the ball travels in this actually made the problem worse because the paper would lean downwards as soon as I let go to fire flicking the ball down and most of the time the g force would keep the ball in the tube. I enjoyed this activity because we had the choice of what to make and how we would make it. I also enjoyed working with other classing and seeing what ideas they came up with. The two main designs we used were slingshots and different forms of catapults. The feedback I have for this activity is to maybe have more challenges for your device, different things to shoot and more materials to use for our devices. Overall I enjoyed this activity and it was very fun. If we were to do choice day again I think we should add a P.E activity or some form of sport like dodge ball and this would be good to do with different age levels in each team.
Here are the activities.
