RADIATION PROTECTION: HOW MUCH IS ENOUGH?

"Thermal Radiation" is a straightforward assessment of future physicists' understanding of radiant energy. They write out answers to questions about wavelength and frequency, temperature relationships, absorption and emission. The...

Gamma radiation, which is harmful, is useful in treating cancers. In the second activity in a series of four, young scientists take surveys and calculate their yearly exposure to ionizing radiation. Then they read about how harmful their...

Enough talk about the Greenhouse Effect—let's actually look at it! Junior climatologists engage in a simple thermodynamics experiment on a cold winter's day to examine global warming. The activity simulates rising carbon dioxide levels...

How much information can we process? How much information is stored inside us? These questions, and many more, inspired an inquisitive installment from a larger video series. From verbal and written language to DNA and computers,...

How far is it from your house to the grocery store? If you answered in time rather than distance, there's a scientific explanation. Science scholars compare distance/time quantities in a short, animated video. Topics include time being...

Is all radiation harmful? The video's narrator interviews unsuspecting citizens to get their take on radiation sources and effects. The resource includes a breakdown of types of radiation and whether each type is capable of causing us harm.

How is it possible that we can feel the heat of a sun that is so far from Earth? Study the type of heat transfer that makes this possible! The video introduces learners to radiation and how it functions when transferring heat. 

In the past century, the global temperature has climbed 10 times faster than the average rate of Ice Age recovery warming. The fifth video in a series of seven on factors that affect climate change discusses just how much global warming...

No question is a silly question! Vsauce is a website that investigates strange questions. Founder and science educator, Michael Stevens, explains the value of the such questions to an audience and demonstrates by working through the...

People associate calories with food, but what is a calorie? Young scientists measure the number of calories in samples of food to better understand the concept. They test a variety of samples, take measurements, and compare their results...
