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...

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...

Incorporate reading strategies, math, research, and the scientific method into one lesson about water conservation. After reading a story about a landlady trying to determine how many people are living in an apartment, learners develop a...

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 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...

What do quantum mechanics and global warming have to do with each other? More than you might think. Surprisingly, this video explains how it's not the energy emitted from the sun that causes the problem, but how the infrared radiation...

Students explore the impact of their lifestyle choices on the environment. For this ecology lesson, students use the web site provided to calculate their ecological footprint. This data is used to construct a class graph and determine...
