This is an activity about the planet Mars. Learners will create cratered surface models illustrating different lengths of time. Then, they will compare their models with three different surface images of Mars, placing these images in order from youngest to oldest based on the evidence. Learners will discover that the oldest surface has the most craters, while also discussing what events could make a surface on a planet both half-craters and half-smooth.
