Join a spaceship mission to Mars to deliver microbes and a variety of plants and animals needed to start an ecosystem. Unfortunately, an onboard explosion has wiped out part of your cargo and you need to help rebuild the ecosystems. You can find the game here: http://pbskids.org/lifeboat/
It is an educational game, which means you’ll learn so much, and you’ll love it if you like biology. Games like this show how fun learning can be.
The graphics aren’t the best, but it didn’t bother us too much because we still loved playing the games!
