Another video on infrared light.

Looking at water and ice with infrared light helps us understand how light and heat are related.

A quick video introduction to infrared light and how it is different from visible light.

The supercontinent Pangaea, with its connected South America and Africa, broke apart 200 million years ago. But the continents haven't stopped shifting -- the tectonic plates beneath our feet (in Earth's two top layers, the lithosphere and the asthenosphere) are still traveling at about the rate your fingernails grow. Michael Molina discusses the catalysts and consequences of continental drift.

the new James Webb Space Telescope (JWST) is designed for detecting infrared radiation. This animation explains what infrared light is, and how the JWST will use it. Please rate and comment, thanks!

Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.

Whether we cry during a sad movie, while chopping onions, or completely involuntarily, our eyes are constantly producing tears. Alex Gendler tracks a particularly watery day in the life of Iris (the iris) as she cycles through basal, reflex and emotional tears.

A Steve Spangler video experiment that might be good for teaching students about the Law of Conservation of Energy. Involves making a solar powered oven to convert light energy to heat energy to cook S'mores.

A good mini-lab that can be used to teach kids about density.

Pour a glass of water and watch it turn to ice instantly! This step-by-step tutorial will show you everything you need to know about Instant Ice.

Want to make a glass of water freeze instantly on command? What is this supernatural power and who can use it? Discover the secrets to Ice-bending ... in real life.

The next time you're eating a big bowl of breakfast cereal, take a closer look at the ingredients. You'll find that it contains more than just wheat and corn. Look closely and you might find iron in your cereal... you know, the metal... the stuff used to make nails. Here's an experiment that proves you're eating iron for breakfast.

Our resident science fiends will give the YouTube audience their big science treat each week with a live experiment where you can find out how to make food dance, power a light bulb with household objects and blow mega smoke rings!

This is the entire collection of Steve Spangler science videos on YouTube. It is an amazing collection of simple videos connected to all aspects of the science currriculum.

This video might be great for teaching polarity and dissolving. We're going to show you how to make water-proof sand! It's fun, easy and awesome!

When you combine sand with a water-resistant chemical you create a hydrophobic substance that can clean up oil spills, give you awesome visuals, and quite possibly hours of fun.

At Head Squeeze, James May and his crack team of sci-geeks, maths-nerds and tech-heads provide answers to all your burning questions. From everyday curiosities to the latest mind blowing discoveries; our experts break it down for you and give their own left-field insights, sideways interpretations and bizarre, entertaining facts.

Head Squeeze is packed full of the latest and current developments in the world of science, technology, and maths. This channel is for anyone who wants to find out how the modern world works. Prepare to have your head squozen!

Huw James took a trek up Mount Etna and decided to show us what actually happens when a volcano erupts!

With a little bit of help from Dr Suze Kundu and using a simple demonstration heating a glass beaker of wax, stone, sand and water we can see what happens when a volcano erupts.

We can actually tell a lot about a volcano looking at the lava that comes out. If the lava is quite dense and thick we know it contains a lot of the compound silica. If it is less dense it has less silica and spreads out a lot more.

Thick lava will generally erupt from one vent and follow one flow down the side of the volcano. Thinner lava, lava that is less dense, generally erupts from the surrounding magma chambers and flows in many different channels.

Have you ever found yourself in the path of molten lava? Has the volcano you're climbing suddenly erupted and you don't know what to do? Well keep watching because Huw James has all you need to know.

The earth is built on tectonic plates that move around on the mantle. Sometimes these plates move around and come together to form mountain chains like the Himalayas, some rub together and set off earthquakes, and some like Mount Etna, interact and one plate goes underneath the other.

A scientist takes a big risk to get a lava sample from the rim of a lava lake.
