Eco-Systems for Pre-Schoolers

How can we teach our young children to appreciate and respect the way in which ecosystems work?  One of the fun and meaningful ways we found is a fish tank that shows the interdependence of plants and fish. Take a look at this child's betta tank - 

This was not showing the child that he needed to take care of a pet. But changing the water and having it at the right balance was beyond the child's developmental level. The solution? We heard about fish tanks that demonstrate the interaction of nature. 

The waste created by the betta in the tank is pumped into the plant section. This waste helps the plants to grow and thrive. What a wonderful way to show children that in nature everything has a place - even waste!  Since the waste is removed from the water, it is clean and clear, making the water a perfect habitat for the betta.  What's even better is the plants grow fast as they love the fish "food" that is recycled to them. Children have a fish that lives in a healthy environment, a garden, and a wonderful example of how an ecosystem works! 

Soon the plants will sprout. They are herbs and can be used in cooking. What an ecosystem where everyone and everything benefits!
