Mini Culmination Prep- Day 4

Today, Lena and I worked together again. Unfortunately, we found out that we have to launch 15 feet, not just 56 inches. This was not so great news for us. I was actually working with the rover again today, with Gillian, but Lena said that in order to make the pieces go 15 feet, we have to multiply our height measurement by 2 1/3 (2.33333) and our weight by 2. Apparently she tested this on a couple things and it worked. phew!! So, as for the rover. We got it to work perfectly!!!!!! we were so happy!! What we did, is because it turned on the way to the Mars base, we made one wheel go slower and one go faster on the way back and so it turned back and ended up in exactly the same place where it started. Yay!!!
