Teacher or professor: SciShow
Subject: Science
Content of the Lesson: From medieval knights to face shields, humans are pretty big fans of armor. But it turns out that other organisms use armor, too! Except sometimes, their armor doesn’t look like anything we’d expect. Hosted by: Rose Bear Don't Walk SciShow has a spinoff podcast! It's called SciShow Tangents.
