Science Struck: How Does Light Travel Through Space and Other Media?

How does the color of the sky change from blue to reds and oranges to black? An illuminating lesson explains how light travels through different mediums using the sun's light as an example. By examining diagrams and illustrations, pupils...

It's a delicate balance—using technology to improve our lives while still protecting the environment, and ourselves, from the hazards of technology use. Class members examine statistics about the increase in media use, complete a survey...

Cancer's ability to quickly spread from one organ to the next makes it one of the most fatal diseases in recent history. Watch as this short video takes you on a trip into the microscopic world of cancer cells, exploring the...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and...

Carve out some time to learn about space-time. Young scientists use a remote learning resource to read up on the relationship between space and time. They consider the idea of relativity, see how objects with a large mass can bend space...

Address the question that physics learners are burning to know the answer to: How does an atom-smashing particle accelerator work? The LHC or Large Hadron Collider is introduced as a tool for uncovering the mysterious rules that govern...

In this lesson for students from 3rd-12th grades will learn to build an experiment chamber to test the effects of light on Brassica rapa roots, and compare their results with outcomes from plant experiments conducted aboard the...
