From healing to astronomy to our connection to the natural world, the lessons from Indigenous knowledge inform our learning and practices today. How do knowledge systems get passed down over generations? Through the knowledge inherited from their Elders and ancestors, Indigenous Peoples throughout North America have observed, practiced, experimented, and interacted with plants, animals, the sky, and the waters over millennia. Knowledge keepers have shared their wisdom with younger people through oral history, stories, ceremonies, and records that took many forms.
