Our species needs, and deserves, a citizenry with minds awake and a basic understanding of how the world works.

Somewhere, something incredible is waiting to be known. - Carl Sagan

The Science Department at Grayslake Central High School endeavors to provide students with the guidance, skills, and experiences necessary to thrive as both conscientious producers and savvy consumers of knowledge in modern society.
