Our Mars study centered around robots and the possibility of people colonizing the planet. The kids made this ecosystem for people to live in on Mars. There are lego buildings, and the green things are supposed to be plants. You can see a little rover outside near a red Martian mountain. Since the solar system's largest volcano, Olympus Mons, is on Mars, they made an erupting volcano. Inevitable but always a hit.
NASA has a program for kids called Rock Around the World. You can send in a rock, and they will analyze it and compare it to Martian rocks. The kids were really excited to send off their rocks to the scientists. You can see Miah's and Larkin's rocks here.
