For everyone out there trying to live sustainably, you might also want to consider the best way for your loved ones to dispose of your body after you're gone. Is a green burial best? What about human composting (where it's legal)? And...

You may think you just have to run more, or lift more weights—but the truth is, there is a scientific way to increase your athletic ability! Join Stefan Chin for a new episode of SciShow and learn how you might be able to perform better,...

Hank serves up a buffet of news items that includes an approximate date for the end of everything, scientific proof that when it comes to sex bigger IS better, and a look behind how the London Olympics are going green. Bon appetit!

In this video Paul Andersen explains how reaction intermediates are created in elementary steps and may not appear as either a reactant or product. Experimentation is used in Chemistry to identify reaction intermediates.

Looking for a mental or physical edge in sports? Here, we'll explore some of the ways that you might be able to perform better while staying safer in your preferred sports ball game.

In this video Paul Andersen explains how Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium. When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure,...

In this video Paul Andersen describes how reversible reactions achieve equilibrium as reactants are converted to products and products are converted to reactants. A model shows how forward reaction rates and reverse reactions rates...

In this video Paul Andersen explains how air pollution is any chemicals in the atmosphere that negatively affect human health. Primary pollutants (like CO, VOCs, NOx, SO2, PM, and Lead) as well as secondary pollutants (like Ozone,...

Paul Andersen explains how the rate law can be used to determined the speed of a reaction over time. Zeroth-order, first-order and second-order reactions are described as well as the overall rate law of a reaction. The rate of a...

From turf toe to toxic Zamboni's, sports injuries aren't just for pro athletes.

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and...

In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Predict future air quality levels using LSTM models for a location of your choice to mitigate air pollution impact.

Molecules like PF5, SF₆ defy the octet rule, with expanded valence shells or unpaired electrons, arising from the availability of d-orbitals or radical stability

Reaction Mechanism & Rate Determining Step part 1

Most UK cities have had illegally polluted air for nearly a decade, and the effect of air pollution is particularly bad on children. Ahead of Clean Air Day, we conducted an experiment to assess the air quality on a school run in central...

In some cities, it's more dangerous to breathe than smoke cigarettes. Find out more breathtaking facts and figures on the dangers of global air pollution.

As we fly around with NASA pilots, we’ll explore Earth’s air space with scientists Annmarie Eldering and Armin Sorooshian -- from wispy clouds high above, to tiny particles that make up air pollution.

Dr. Bryan N. Duncan is a deputy project scientist for the Aura Mission at NASA's Goddard Space Flight Center in Greenbelt, Maryland.



He recently presented the story of air quality in three cities: Beijing, Los Angeles...

Using new, high-resolution global satellite maps of air quality indicators, NASA scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe. The United States, Europe and Japan...

What exactly is Le Chatelier's Principle? And why is it important to learn it to understand chemical reactions?

Pandemic-related shutdowns have affected how people act, so scientists began monitoring how that’s affected the planet — specifically nitrogen dioxide emissions. How do COVID-19 pollution patterns play into NASA computer...

Learn the basics about Reactions of copper. What does copper react to? How is the chemical reaction of copper noticed? Find out more in this video!

Learn about the Haber Process and the uses of Ammonia within the overall reactions topic.
