The term ecosystem is referred to the environment where the organisms function along with non-living elements of environment and then interact with each other to form a kind of biological community. Educating about ecosystems for kids is very important in order to understand how human life is operating and how all other species are depending on each other and also environment around them for the survival. In case you want to concentrate on aquatic ecosystems, then you can take the advantage of several lessons and activities in order to help them understand how fresh water and marine organisms operate.
Virtual Pond: Internet is the best source to explore about virtual pond, and then use it to teach ecosystems for kids. You can explore by using Canterbury Environmental Education Centre’s Naturegrid site.

Ecosystem in the bottle: Help the kids to create their bottle habitat so that they can easily learn about the aquatic ecosystems.

Make those 2 soda bottles into the miniature aquarium and then fill the bottle bottom with the sand, by adding living organisms and water. Teaching ecosystems for kids in this way is very easy, tell them to observe habitat over for 4 weeks and then record what they observed in journals.
Chesapeake Bay Activity book: You can download this from internet and distribute by taking printout. These books provide games, educational materials, and activities to help in learning about ecosystems for kids. Children can learn about wetlands, species types and watersheds that may inhabit bay.
