In this online Flash game, learners experiment with an ecosystem, trying to find a balance between weebits, their plant food source, and the right climate to keep the plants growing. Weebits are small creatures that live on plants. When they get big enough, they divide, making two weebits. Learners try to produce the largest number of weebits by feeding them plants and making sure the plants have water. This game has three levels (easy, not so easy, not at all easy) which learners can master.
