Welcome to Cosmo’s World,

Join Cosmo the flying squirrel, Terra the river otter and their friends on a journey of discovery through Pennsylvania’s natural landscapes. Learn about Pennsylvania’s biodiversity, invasive species, endangered species and how climate change may affect Pennsylvania’s plants and animals.

Cosmo’s World was produced by the Wild Resource Conservation Program and PBS 39 to help classroom teachers and environmental educators teach these elementary school science standards in a fun and engaging way.

We hope you enjoy the videos and the accompanying lesson plans.
