If you've spent any time trying to explode a pumpkin with rubber bands you know that they have a distinct smell to them when stretched, and you have physics to thank for that.

Join SciShow Space as we explore Neptune's largest moon, Triton. It's kind of a weird place and may even have liquid water!

Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there's one foundational invention that almost everything else relies upon: the...

In today’s episode we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics....

Hot Air Balloons! They're those big, beautiful balloons people can float up to the sky in-- but how do they get up there?!

Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

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...

SciShow takes you to Centralia, Pennsylvania, site of one of the oldest, biggest coal fires in the United States, and explains the chemistry of spontaneous combustion.

In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either chromatography...

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Humans often take inspiration from nature when coming up with inventions, and this includes breakthroughs in fabric design that help to forward the fabulous and functional world of fashion.

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep your warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks...

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.

Why does fire burn? What's the chemistry and physics of a flame? This week, learn about the beautiful science happening inside a flame!

Paul Andersen explains how organisms are able to regulate their internal body temperature (or not). He starts with a brief description conduction, convection, radiation and metabolism. He contrasts ectotherms and endotherms. He also...

Different fuels create different types of fires, and each one needs to be extinguished using a specific strategy. Do you know which class of extinguisher is needed for different fires?

Mr. Andersen shows you how to sink leaf chads in preparation for the AP Biology photosynthesis lab. An empty syringe is used to remove gas from the leaves before the lab. As the chloroplasts absorb light they produce oxygen bubbles which...

In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V diagram...

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

This week we are looking at renewable energy sources and why we need them. We’ll explore hydropower, wind, geothermal, and solar power, as well as some of the challenges, and how engineers are working to make their use more widespread.

Join SciShow Space as we complete our tour of the Solar System planets with the ice giants, Uranus and Neptune.

When you burn fat, where does it go? Many people, even some doctors, think it's just "burned up." But that's not possible! Find out where your fat really goes!

Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Explore homeostasis with the Amoeba Sisters and learn how homeostasis relates to feedback in the human body. This video gives examples of negative feedback (temperature and blood glucose regulation) and positive feedback (events in...
