Who Turned Out the Lights?

Astound your aspiring physicists with a simple demonstration of refraction. They watch as you allow a stream of water to spray out of a hole in an aluminum can. Then, as you shine a light down from the top opening, its path follows and...

How much energy does it take to light a room? Class members calculate the total wattage it takes to light the classroom. Through calculations, responsible scientists determine the cost of energy for the year, then figure out how much...

Could you reinvent the light bulb? Scholars tap into their inner Thomas Edisons to build a light bulb prototype out of a jar and some wires. They see how long the filament wire glows in the jar (batteries not included) to measure their...

In this electric light bulb worksheet, students answer short answer questions about an electric light bulb by pretending they are answering interview questions and they are the light bulb. Students complete 7 questions total.

While we are all familiar with what happens when you turn on a light bulb, Albert Einstein was convinced that there was more happening than meets the eye. The video describes his extension of the research of others to ultimately...

How do you get the most light out of a light bulb? That's the task Max Planck took on, and it turned out to be rather...enlightening! The illustrated video introduces physics scholars to Planck's plight, which ultimately changed our...

Why so blue? As it turns out, very few things in nature only reflect blue light! A short video from a comprehensive science playlist highlights the beautiful blues of butterflies, birds, and human eyes. The narrator shows how adaptations...

It doesn't matter how old you are or where you live, you can help protect the environment. Created in 2005 for World Environment Day, the agreement shows that the simple steps one can take to make a change have stayed the same, despite...

Medicine has gone high tech. But how do the new, less invasive diagnostic tools work? An engaging short video sheds light on how integrated photonics is revolutionizing the medical sensor industry.

An impressive animation explains the earth's awe-inspiring auroras. The contributions of high-energy particles from the sun collide with our neutral atmospheric atoms. Explained are the roles of solar wind, plasma, the magnetosphere,...
