Robotics
We used sand because it is made up of a lot of little minerals just like lunar soil because we couldn't go to the boon and get lunar soil and the lunar soil could get into your lungs and tare up your insides and you could die.
we built our robot and then it was not working and then I had to give back the large moter and we had to restart the hole robot then we had 5 minuets left so we made him he ended up not working.
