Biodiversity
Understand that biodiversity — the variety of different species in an ecosystem — is essential for healthy ecosystems, and that keystone species (like wolves in Yellowstone, sea otters in kelp forests, or bees as pollinators) have an outsized impact on their ecosystem, so that losing one key species can cause a cascade of changes affecting many others
Typical age: 9–11 years
“If your child learns about how wolves were brought back to Yellowstone and the whole ecosystem changed, can they explain what a 'keystone species' is and why having many different species in an area matters?”
