An astrobiologist and a physicist explain how mathematics is universally critical to helping understand nature and the cosmos in this video from KAET. In the accompanying classroom activity, students discuss the mathematics in the video, including the use of algebra, and then practice writing, reading, and evaluating algebraic expressions in a class bingo game.

Special thanks to Dr. Sara Walker, astrobiologist and physicist at Arizona State University in Tempe, AZ.
