In Rūma 2 we have been studying simple machines, and how they work to help us solve problems. We had a go at making lots of simple machines like levers, axels and pulleys.

Then we used the design process to make catapults to solve a problem. We all had different problems to solve with our catapults.
After we designed and made them, we decided what we needed to change to improve them. We called this debugging or modifying.
