Despite the diverse appearance and characteristics of organisms on Earth, the chemicals that make up living things are remarkably similar, often identical. In this episode of Crash Course Biology, we’ll look at the building blocks of the...

In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses...

Atoms are the basic building blocks of all matter and they are very very small. They are made up of protons, neutrons and electrons and they are the smallest unit of matter that still retains the basic properties of an element.

There are 4 main types of carbon-based molecules important to life. They are the building blocks for every living organism on this planet. In this video, I will give you a quick introduction to each type with some fun examples.

NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research gives support to the theory that a...

Jump into 'What Shape Is A Molecule?' to explore the tiny, invisible building blocks of everything around us! A quick, fascinating peek into chemistry, perfect for curious young minds.

Explore 'How Are Molecules Made?' to see how tiny atoms join hands to form everything in the world! A quick, magical journey into the building blocks of nature, made fun for kids.

Upon viewing the Exploring the Building Blocks of Matter video series, students will be able to do the following: Understand that the quest to better understand the building blocks of matter has transpired over the past several thousand...

Hank and PhD candidate Casey Massena go deep into the chemistry of a molecule that Casey helped create! Then Jessi joins the show to show off Ecuador, one of her many conures!

All the complexity in the universe ultimately owes its existence to one of the simplest materials possible: molecular hydrogen. And not only did this molecule play a huge role in building the universe as we know it, today, it also helps...

Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

Although we've spent a lot of time in this series looking at human-made organic chemicals, the term "organic chemistry" was originally used to describe molecules isolated from living things. In this episode of Crash Course Organic...

Paul Andersen describes the four major biological molecules found in living things. He begins with a brief discussion of polymerization. Dehydration synthesis is used to connect monomers into polymers and hydrolysis breaks them down...

What do macaroni salad and gasoline have in common? They are made of exactly the same stuff -- specifically, the same atoms, just rearranged. So, while we put the former in our mouths and the latter in our cars, they are really just...

Video on QM of Atoms which may clarify some concepts:    • The Quantum Mechanical model of an atom. W...  

Why do atoms combine to form molecules? The quantum mechanics of chemical bonds and chemistry....

The video explains the process of protein synthesis, how information from DNA is used to build complex protein molecules from simpler amino acids, and how the order of bases controls the order in which amino acids are assembled,...

Alkanes are kind of the wallflowers of organic chemistry, but they still have important functions in the world around us. In this episode of Crash Course Organic Chemistry we’re building our knowledge of organic molecules by learning all...

Alkenes are an important type of molecule in organic chemistry that we’re going to see a lot more of in this series. But before we can really get into the many cool reactions alkenes do, we need to go over some of the basics. In this...

In the first physical science video for the Next Generation Science Standards Paul Andersen explains the structure and properties of matter. He starts by explaining how all matter is made of about 100 smaller particles called matter. ...

You might not believe it, but the same chemistry that brought us bulletproof vests and modern sailing sails also gave us the technology to build your smart phone. But that doesn’t mean these chemists were thinking about these...

Metabolism is a complex process that has a lot more going on than personal trainers and commercials might have you believe. Today we are exploring some of its key parts, including vital nutrients -- such as water, vitamins,...

Wouldn't it be nice if our transportation was as sleek as in The Jetsons or Futurama? Flying cars are cool, but what about a giant network of human-sized tubes that run through buildings and across entire cities? Well guess what? The...

Low-E windows have reduced the amount of energy required to heat and cool our buildings, a critical step in fighting climate change. But new research suggests we've lost something beneficial in the process.
