3D model of Orion

In this activity we are going to calculate the distances between the stars in the Orion constellation. We use simple mathematics to convert real distances between the stars in space to 3-dimensional positions in a model built on a table in your classroom. Through this excercise we will experience how astronomers find distances using parallax and how much a constellation will change if we change our perspective.
