We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first appears. In...

Across the world, and throughout history, different peoples have developed different ways to deal with their own waste. And while they didn’t always nail the design, their efforts to keep themselves safe have led to the thrones and...

Hank tells us the stories of three experiments in biology that, with creativity and luck, changed science & the world with it in their work to solve the mysteries of the universe.

This week we continue to spend quality time with gases, more deeply investigating some principles regarding pressure - including John Dalton's Law of Partial Pressures, vapor pressure - and demonstrating the method for collecting gas...

Want to learn more about the topic in this week's video? Here are some keywords/phrases to get your googling started: greenhouse gases, climate change, radiative forcing,

We all do it, but why? Hank explains the whys and hows of our gaseous emissions.

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 for...

Over just 20 years, the Stingray nebula has become anywhere from 29 to 900 times dimmer! It could teach us a ton about how nebulas evolve over time, and what happens when everything is going a lot faster than expected.

We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

We’re all excited about the Mars rover Perseverance this week, but scientists are also working on some other exciting things!

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...

Have you ever heard the phrase, 'You look like a Million Bucks?' Well, you do... but you also look like a million particles. In this episode, Sabrina talks to us about matter and particles and that all matter is made up of particles....

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

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.

Squeaks can't sleep because the sun is too bright, and Sam the Bat stops by to talk about what makes the sun so special DCI: ESS1.A: Patterns of the motion of the sun, moon, and stars in the sky can be observed, described, and predicted.

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is...

Mister Brown and Squeaks are making bread, and they're going to need a tiny little helper to get the job done: a fungus called yeast! Disciplinary Core Idea: PS1.B: Chemical Reactions - Heating or cooling a substance may cause changes...

If you’re trying to figure out where to plan on sheltering during the zombie apocalypse, it’s essential to know whether zombies sink or float!

We have some good news this week for all the James Webb fans out there, as well as a look a some creative chemistry that may help us find the first solid evidence of an exomoon!

This week, Hank elaborates on why Fugu can kill you by illustrating the ideas of solutions and discussing molarity, molality, and mass percent. Also, why polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar...

Today we’re going to take a closer look at these beautiful but dangerous landforms as we explore the different types of volcanoes and trace the patterns of volcanic activity around the world. From the explosive power of a stratovolcano...

How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this episode of Crash Course Physics, Shini talks...

The word "mole" suggests a small, furry burrowing animal to many. But in this lesson, we look at the concept of the mole in chemistry. Learn the incredible magnitude of the mole--and how something so big can help us calculate the tiniest...

In this video Paul Andersen describes the four major spheres on planet Earth. The geosphere makes up the mass of the planet and includes the major landforms. The hydrosphere is all of the water and the atmosphere is all of the gases. The...
