Wonder Project- Lesson 5

 Kia Ora bloggers, 

Today we had another Wonder Project lesson. We mainly talked about stability and how our rockets would fly. 

We had to find the centre of mass which we had to balance the bottle with a string where it would be stable and balancing on each side. Then we had to find the centre of pressure which we had to make a trace of our bottle then balance it on a ruler and where ever the trace of our bottle balances we make a line.

Then we had to take our bottle and put the trace over it. Where ever the line was on the trace we had to make a line on our bottle. When we finished that we had to do the stability test. Our group had to redo the fins because they were not the same size as each other.

We remade the fins then we had to find the centre of pressure. This one was a bit hard for our group but we managed to get it done. Then my friend who was already finished helped us do the stability test, our rocket was good and we finished.

Here are some photos!
