Yesterday we went to the Stem Lab in Worcester.We all did an activity called Leg Up, this activity wasnt all that fun but it was very educational, the activity was to simulate the problems that the astronauts have in space. We worked on that activity for a while and then we talked about it and what we found.After that we had about a half an hour to desighn a CEV which is a space vehichle.That was pretty fun.Then it was lunch time PIZZA! very good. Afterwards we built our CEV and then we presented it this was a pretty fun day.
