In this video Paul Andersen shows you how to ask questions in a mini-lesson on evaluating questions. Two examples are included in the video and two additional examples are included in the linked thinking slides. <br/>

What was the 2012 Nobel Prize in physics given for? Capturing a single photon of light!

Humans may use fiber optic technology to make everything from novelty desk toys to high speed internet cables, but Nature has its own ideas. For decades, scientists have debated to what extent polar bears may use the optical properties...

Some people have this idea that dead batteries bounce if you drop them, but is it true?

Scientists think they’ve discovered some peaks taller than Mt Everest deep beneath the earth’s crust, and this range might be the key to one of the biggest mysteries in geology!

We often think of the ocean’s tide as a simple rise and fall, connected to the motion of the Moon. But on any given shore, the reality is much more complex and oceanic scientists have realized recently that there’s another, more...

Many ancient sites had some truly amazing effects on sound waves, suggesting that early cultures may have built spaces to evoke certain sensation. And by studying the acoustics of these structures, we can learn new things...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation...

Some people have this idea that dead batteries bounce if you drop them, but is it true?

This video is about the Portal Paradox - a paradox in the video game Portal (and Portal 2) regarding whether or not a companion cube passing through a moving portal plops out of the other end with no speed (velocity,...

Scientists have warned that as CO2 levels in the atmosphere rise an increase in Earth's temperature by even two degrees could lead to catastrophic effects across the world. But how can such a tiny, measurable change in one factor lead to...

In some parts of the United States, it's said that a green sky means there's a tornado on the way. But while you should probably go inside, things might not necessarily get so bad"

We learned how motion gives matter its mass, but how does motion affect time? Let's dive deeper into the true nature of matter and mass by exploring Einstein's photon clock thought experiment, and the phenomenon that is time dilation.

All telescopes work by gathering light from the stars, but one held the crown for square footage for collecting that light for 53 years. The amazing Arecibo.

What is mass and what does it have to do with the Higgs Boson?

This video is the first of a five part series on scientific inquiry. Supporting material can be found below.

How do you engineer stealth? Sneak a peek at the methods employed to hide aircraft and boats from detection.

All the complexity in the universe ultimately owes its existence to one of the simplest materials possible: molecular hydrogen. And not only did this molecule play a huge role in building the universe as we know it, today, it also helps...

You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.

We'd like to know why you're staring at yourself in a spoon in the first place. But we can at least answer the question of why you look upside-down when you do.
