My World is Upside Down

Why can some organisms detect polarized light, but others can't? Scholars observe as the narrator constructs, demonstrates, and explains a simple polarimeter during a video from a larger playlist covering physics. Concepts include how...

This video highlights three experiments that change the way people think about the world. First up, scientists measure gravity. Next, it discusses the debate surrounding whether light is a wave or a particle. Finally, the atomic model...

Is it possible to travel faster than the speed of light? In a word, no—not so far, at least! Explore the possibilities with a video from Veritasium. The narrator responds to viewer-submitted ideas for creating devices or conditions that...

Chiton are mollusks that have no face, but have many eyes made from a component found in limestone. Here is a video that introduces nine ways animals see the world, including through rock eyes like chiton. Viewers learn about a vision...

And the prize for oldest living thing on Earth goes to . . . In this video from PBS Digital Studios, viewers learn about the oldest living things on Earth, all over 2,000 years old, such as bristlecone pines, baobab, sea grass,...

Create movement with some wire and a magnet! The video instructor demonstrates how to use electromagnetic induction to power a miniature train. Using the installment of a physics playlist, youth learn the science behind the process.

An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

In this light worksheet, students construct a pinhole viewer using a paper box, wax paper, tape and a pushpin. They answer six questions about their observations, the orientation of the images they saw, and the results of their experiment.

If you are up for constructing a wooden frame, you can do this demonstration of the interference patterns when light reflects off of layers of soapy film. Both constructive and destructive interference can be seen as evidenced by the...

A video that demonstrates the process for cooling atoms launches a journey to comprehend physics. After watching the video, class members answer multiple-choice and short-answer questions to prepare for a whole-class discussion of the...
