// Test which material is best for a job

Tuesday: Strong, soft, bendy

Rocket builds a tiny bridge for toy cars.

He uses one sheet of paper. The first car falls through!

"Oops! That is okay," Rocket laughs. "Mistakes help us learn."

"What do you notice about the paper?" Raven asks.

Nova beeps. "Hint: a bridge needs a strong material."

More jobs, more properties

A bridge must be strong.

Strong means it can hold weight without bending too much.

A hair tie must be flexible, so it can stretch.

A bed must be soft and comfy.

Engineers choose materials by their properties.
