Join the Amoeba Sisters in this longer review video as they review food chains, food webs, how energy flows through trophic levels (including the 10% rule), ecological relationships (including parasitism, mutualism, and commensalism),...

Ammonia is extremely useful to us as a crucial ingredient in fertilizers. But producing it also has a significant carbon footprint, which is why scientists have been on the hunt for a way to make ammonia production greener.

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

Humans have relied on fertilizers to grow their plants for thousands of years. But the production of synthetic fertilizers also requires an immense amount of energy that comes primarily from fossil fuels and therefore contributes to...

Many folks in the southeastern US know that the invasive vine kudzu swallows cars, utility poles, and entire mountainsides. They may not know it also contributes to air pollution and even makes it harder for us to ensure that everyone...

Atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A...

"The bends" is one of the biggest risks that humans have to deal with when diving, but why don't marine animals, which are diving all the time, get them?

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected...

Have you ever wondered where cured meats like salami or pepperoni get their bright red color? Of course its from organic chemistry! A chemical called nitric acid gives them that bright color, while also increasing their shelf. It's also...

In this video Paul Andersen explains how equilibrium is achieved in a reversible reaction. When the rate of the forward reaction is equal to the rate of the reverse reaction the system is at equilibrium. Graphical analysis of...

Hank describes the desperate need many organisms have for nutrients (specifically nitrogen and phosphorus) and how they go about getting them via the nitrogen and phosphorus cycles.

We just finished looking at some catalytic hydrogenation reactions, so let's look at another extremely important application of hydrogen gas. Ammonia is a critically important compound for many reasons, particularly fertilizer production...

Nitrogen is integral to the production of protein and DNA. Discover how it is present on Earth in a constant cycle, and how nitrogen from the air enters the food chain. Biology - Ecosystems - Learning Points. The nitrogen cycle describes...

This video is explaining how nitrogen cycle works for kids.

Dr. Forrester will focus on the nitrogen cycle. She will define and explain how the cycle works.

Pluto has a thin atmosphere, let's learn about it!

I pour Liquid Nitrogen, Diethyl Ether, and Dry Ice into my pool! Can liquid nitrogen put out a fire? what about dry ice? <br/>
Diethyl ether is one of the most flammable solvents around!

The video explains how to calculate energy changes in chemical reactions by considering the energy required to break bonds and the energy released when bonds are formed. The video also introduces the concept of bond energy, which is the...

The video discusses the measurement of the volume of gases, with a focus on Avogadro's law, molar gas volume, and how to calculate the volume of a gas from its mass. The presenter explains the theory behind each concept and demonstrates...

In this video, we will discuss the 1) results & 2) theory underlying the nitrate reduction test (nitrate broth).<b<br/>r/>

Results are first, and theory (somewhat compli<br/>cated) begins at 7:55.

This video explores the issue of dead zones in water bodies around the world, caused by the release of nitrogen and phosphorus from wastewater and agricultural runoff. The expedition team investigates the impact of these pollutants on...

James, our master of microscopes, is not a farmer. He is, to put it simply, fascinated by microbes. And that may lead him to strange places and cause him to grow tanks full of weird things. But he is not a farmer.
