The ocean provides much of the world's oxygen. Science Questers take part in a water ceremony, something that many indigenous nations perform to honour water, a living being. Saltwater and cedar are used for spiritual cleansing. An animated sequence shows us the huge patch of plastic garbage floating in the Pacific.  'Qátuwas (Jessica Brown) of Heiltsuk and Nuu-chah-nulth heritage brings indigenous knowledge to ocean science, and we learn about ocean thermal vents. Kai shows the effects of acidification on ocean life, and we learn from Jesse Hemphill and the Gwa'sala-'Nakwaxda'xw people about harvesting herring roe. Planet earth is mostly water. Water is sacred. Indigenous science is about building relationship with place - connecting with land and water. COYOTE'S CRAZY SMART SCIENCE SHOW (Coyote Science) is a visually stunning, award-winning adventures-in-science series designed for elementary students. Drawing on wisdom from pioneers in Indigenous education, including Dr. Leroy Little Bear, Amethyst First Rider, and Dr. Lorna Williams, Coyote Science bridges the worlds of Indigenous and Western science, teaching kids scientific concepts through discussions with Indigenous scientists, storytelling, animation, music, and experiments. BIO: Created by Loretta Todd, a Métis-Cree filmmaker who was one of the first Indigenous women to pursue film studies at Simon Fraser University in BC. Loretta is an amateur science geek who always wanted to inspire Indigenous children and youth to learn more about science, especially Indigenous science. Using her creative skills as a creative, L. S. Todd is an internationally acclaimed, award-winning filmmaker known for powerful, visual storytelling and cultural leadership. Isa, our youth host, shares how water is sacred and water is life. Join our Questers as they give thanks to the ocean, with a water ceremony led by T'uy'tanat-Cease Wyss and Senaqwila. And we meet 'Qátuw̓ as Jessica Brown, who brings Indigenous science to the field of oceanography. Shayla Stonechild is concerned about the damage we're doing to the ocean with all the plastic we throwaway. And DJ Salmon reminds us to never, ever litter, while Anostin and Quinn encourage Indigenous youth to be leaders as stewards of the ocean. Kai shows the effects of acidification on ocean life and Jessie Hemphill, from the Gwa'sala-'Nakwaxda'xw Nations, takes us on a herring roe gathering journey. Commander John Herrington explores what we know about where all this water happened on earth.
