You know it, and you love it. Fried food! But there’s more to fried dishes than just plopping food into hot oil. You have to know what’s up with the food you’re cooking and what oils will work best for you dish.

Even if you don't want to eat them, your apple cores still have plenty of energy left to give. SciShow explores how cities are capturing that energy and turning it into fuel.

In this video Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy.

Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber --...

You ever think about where your trash goes? How long it takes to decompose? And whether your garbage can become ... dangerous? You should! Hank explains the science of trash, how we've dealt with it (or not) over the ages, and both the...

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...

As the population grows, the demand for food is only going to increase, but luckily, scientists are already working to solve this problem.

Are there ways to terraform Mars -- that is, make it habitable for humans? Some scientists think so. They have big plans, but they also face some big obstacles.

Paul Andersen explains the process of anaerobic respiration. This process involves glycolysis and fermentation and allows organisms to survive without oxygen. Lactic acid fermentation is used in animals and bacteria and uses lactate as...

Paul Andersen explains how paraffin vapor combusts in a candle. He also describes energy and mass conversion and almost burns himself.

Paul Andersen explains the importance and location of interstitial fluid. He describes both the hydrostatic and osmotic pressures that move fluid between the interstitial fluid and the capillary. He also explains the major function of...

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!

The technology we use to keep cool is heating the world in a vicious feedback cycle, so we need to improve it and use it less.

Over its lifetime, the Earth has seen plenty of climate change. About 50 million years ago the planet experienced extreme cooling, and all from a little fern.

In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used...

Alcohol has been an important part of human culture for a very long time, and from the basic process, we've figured out how to create a wide variety of alcohol beverages!

Stars blowing up is a surprisingly common occurrence, but who would have thought to search the bottom of the ocean if you were trying to study them?!

Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.

There's two times more carbon in the earth's soil than in all of its vegetation and the atmosphere -- combined. Biogeochemist Asmeret Asefaw Berhe dives into the science of soil and shares how we could use its awesome carbon-trapping...

Deep in the ocean, fluffy bits of organic matter fall like snow. But this marine snow isn’t just pretty; it’s an essential part of our ocean food webs and our global climate!

In this video Paul Andersen explains how the chloroplast in plants harnesses power from the Sun to form high energy molecules like glucose. The structure of a chloroplast as well as a brief discussion of the light reaction and Calvin...

In this video Paul Andersen explains how matter and energy flow and cycle through systems. He starts by explaining how energy and matter input and output will always be conserved. He addresses the many misconceptions surround energy...

Paul Andersen gives you a brief introduction to the cell membrane. He starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. He gives an overview of the fluid mosaic model inside cells. He...
