About This Lesson
Think about all the different ways humans rely on light each day. Imagine trying to drive or cross the road without any streetlights. How would hospitals and schools function without light?
In this PBS lesson, students will learn about emerging technologies that have helped inventors seek new settings for light sources, including in remote and high-poverty parts of the world. To better understand how light allows humans to live and thrive, students will invent their own light source using the steps of the invention process.
