The preschool welcomed a special visitor Monday, as Harker parent and NASA employee Rochelle Ribeiro (Zachary Mascarenhas, kindergarten) joined the transitional kindergarten students in the STEM lab to teach them about space travel. She brought in models of the spaceships; fruit flies that astronauts will be taking to space to study (they are really tiny!); and an astronaut suit, including gloves and helmet that the children were able to try on. The kids had lots of fun on a sunny spring day!
