Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system....

Ovens are great for baking, cooking, and.... discovering quantum mechanics? In this fascinating episode of SciShow, Hank takes you through the science of quantum mechanics, and how ovens played a big part in their discovery.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on energy and energy transfer.

Movies like Predator reveal how useful thermal imaging goggles can be, but why do hot objects give off infrared radiation to begin with?

It’s summertime and people are out camping, barbecuing, and using FIRE! But what’s a better fuel to use for your summer activities? Wood or charcoal? There are pros and cons to both fuels, so check out this episode of SciShow to decide...

Today we’re talking about heat transfer and the different mechanisms behind it. We’ll explore conduction, the thermal conductivity of materials, convection, boundary layers, and radiation.

Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources

What Happens To Your Energy when you Die? During the time that you will be watching this video, 500 people around the world will die. Their thoughts, their hopes, their dreams no longer with us. ...

Certain mathematical equations contain unnerving dangers, Arguably, E=mc^2 is the most famous equation in science. C is a very large number. But in Einstein’s, equation it is squared. This means that mass contains an insane...

“Interconnected Ecosystems” explores interdependent relationships between living things in various biomes.

This video explores how energy can be transferred from place to place. Throughhands-on activities students investigate how sound and electrical energy is transferred. This program correlates to the following Next Generation Science...

An igloo is made of compressed snow. Compact hardened snow is a great insulator of heat because snow is nothing but semi-frozen water with roughly 95% trapped air. The air molecules trapped between the tiny ice crystals create air...

Revealed: the tremendous heat created and energy 'lost' when cars brake. Physics - Energy And Radioactivity - Learning Points. Car brakes convert kinetic energy into heat energy. When you press the car brake pad a system of levers and...

Energy comes in many forms. What are they, how do they differ and what can they be used for? Physics - Energy And Radioactivity - Learning Points. Energy is converted or transferred, but never lost. Energy is measured in joules (j)....

Everything we eat contains calories. We need them to function and carry out everyday tasks. How do we know which foods are right to eat and which contain 'empty calories'? Chemistry - Chemical Industries - Learning Points. Calories are...

Discover how elements are formed in the centre of stars, and how some elements are formed in even more spectacular conditions. Chemistry - Periodic Table - Learning Points. Most elements were created in space. At the beginning of the...

We use two cans, one painted black and the other painted white, to investigate heat absorption. The containers are placed in front of a heat source and the temperature change is recorded. This shows that the black container absorbs heat...
