Driving Question: How are changes in climate impacting amphibians in our ecosystems?
Amphibians can tell us about the health of wetlands. Low populations can be signs of things like pollution or other ecosystem issues. Hear from scientists, volunteers, and actors who are exploring climate change through phenology. Then, learn what people can do to help protect our froggy friends and their homes.
Let's take a look
Meet the Changemakers
Get to know the historians. Each historian in this episode has a card with information about that historian.
There are 5 cards to read.

Quote from a historian
“Science is just a process. It’s a process of understanding the world and asking questions and thinking about creative ways to figure out answers to that question. And it’s something that anybody can do.”
