Nature Works Everywhere is a great, free site from The Nature Conservancy and Discovery Education. The site has resources to help learn about how nature works and the fact that nature is a factory, making many of the things we need.
There is an interactive online game that helps students discover the connections between everyday items and nature's resources, interactive lesson plans about topics like pollinators, forestry, coastal erosion and more, videos about how nature works to benefit us and how we can preserve nature, and a section about scientists working to preserve nature and keep it productive. There are even some virtual field trips.
