How big are the canyons on Mars?
In this game, students superimpose familiar objects onto images of canyons on Mars to get an idea of just how big they are. Objects include a school bus, stadium, Texas, Hawaii, and the contiguous US. Informative feedback makes the activity educational as well as fun. Students then discuss/research the potential of space travel to Mars through the lens of an astronaut. This activity aligns with NGSS MS-ES1-3.
