We are taking part in a very special Science investigation. We have sowed 200 rocket seeds out of which 100 have been in a real rocket! These 100 seeds have spent several months in the International Space Station and have been part of British ESA astronaut Tim Peake’s Principia mission. The rockets were sent back to Earth last month  and our task now is to see whether the 100 seeds that have been in space grow the same as the 100 that have not been in space.
