Educator Guide: Evaporation by Light and Scaling Telescopes

Just when we all thought we had evaporation all figured out, clever experiments shine a new light on old assumptions. A new study points to light having the ability to help sever bonds (a type of intermolecular force) between water molecules to boost evaporation. Learn how these findings support new scientific claims and challenge the old notion that light affects evaporation only indirectly, through heat generation.

The Giant Magellan Telescope could reveal signs of life on faraway planets — mainly because of the telescope’s massive mirrors. But just how big are they? Use this article to investigate the benefits of using scale and relative values in writing. Then solve a related word problem and devise your own useful examples of scale.
