Explainer: What are polymers?
Polymers, whether natural or artificial, are big molecules made by linking up smaller repeating chemical units. The most common “backbones” for polymers are chains of carbon or silicon, each of which can bond to four other atoms.

Scientists Say: Radar
This is a system used to detect objects large and small. It works by sending out radio waves and waiting for them to bounce back.

Scientists Say: Refraction
Light or sound may bend as it travels from one medium, such as air, to another, such as water. This bending is called refraction.
