It's the year 2020, and Gemma and her family are training to be the first family to live on Mars. When there's a fire in their home at the training base they have to prove they are real pioneers.
Gemma was good at inventing useful things. Imagine you are at the Mars training base. Design an invention that would be useful on Mars. What would you need to build it? Draw a diagram of your invention. Write a short explanation of how it works. Show the invention to your family. Can they help you improve it?
