Minute Physics: What Is Dark Matter?

Curated and Reviewed by Lesson Planet

It's hard to explain stuff you can't see! But, this animated stick-figure drawing describes dark matter and how we know it exists. It likens the galaxy to a merry-go-round, holding the stars on their circular path. The one-minute explanation is sufficient, and makes a fun addition to your astrophysics unit.
