The Universe has captured our curiosity and imagination since time began. In this activity, students work together to determine how our planets are arranged in our solar system, and their relative distances from the Earth and the Sun. Using inflatable models and broad scale mapping, we uncover the importance of measurement, as actual relative distances between objects, stars and planets are revealed. We then discover how technologies can be used to determine which objects are closer and which are further away, before playing with ideas on how we as humans perceive distance. Be amazed as your students channel their inner Astronomer and we explore our universe together.
