How does salt affect plant growth, like when we use salt to de-ice snowy winter roads? How does adding fertilizer to the soil help or hurt the plants? What type of soil best purifies the water? All these questions and more can be answered by building a terrarium-aquarium system to discover how these systems are connected together.
Kids can build a complete ecosystem out of stuff you'd normally throw away! Not only that, they can also change the climate and environment conditions and see how plant and animal life are affected. This makes for a fun and interactive lesson in biology, plant life, life science, animals, insects, and water systems.
