Indigenous Scientists look inside the earth and rock layers to learn about the Earth's history. And Archeology gives us evidence about how our ancestors used to live. Elders say that rocks are the oldest beings and we call them Grandfather. In Iceland, Kai and Anostin learn that nearly 90% of Iceland’s homes are heated with underground power, aka Geothermal Energy. Our Science Questers in the Okanagan Nation head to a traditional Winter House to meet with Elder Eric Mitchell, who brings us inside to show how their winter house, or, pithouse, is structured. Karen Rose Thomas from Tsleil-Waututh Nation can't wait to tell us about her exciting world of archeology digs. Plus, Kai makes a model to demonstrate how geothermal energy works. Commander John Herrington breaks down the anatomy of the earth—it’s sort of like an onion! SisterClan shares a beautiful song with us and we share an animation story about Joah and her geologist Grandmother.
