What does it take to see in the dark?

Humans need light to see what is around them. Sometimes it is easy to identify the source of that light—the sun, the moon, an overhead light blub—while other times it can be a bit confusing. How can we see a glow-in-the-dark picture? How do night vision goggles work? And how do augmented and virtual reality technology use light to have us see things that aren’t even there?

Using the overarching phenomenon of night vision and the theme of secret missions, students will explore different sources of light and illumination as they ask themselves: “What would I do to be seen and what would I do to stay hidden?”
