New ReviewThis video uses colorful imagery and animations to illustrate how matter is made of tiny particles. The nature of atoms and molecules is explored through instructive imagery. The video correlates to the Next Generation Science Standard...

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.

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 and Elements: Defining Terms distinguishes the differences between an atom, an element, a molecule, and a compound.

In this video, we'll be talking about how to determine the number of protons, neutrons, and electrons in an ion. We'll be using the periodic table to help us out, so don't miss it!

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...

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. ...

In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy....

A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and...

In this video Paul Andersen describes the positive force intermolecular forces found between all atoms and molecules. As electrons are distributed unevenly it creates instantaneous dipoles which hold molecules together. This force even...

Today's Crash Course Chemistry takes a historical perspective on the creation of the science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of how we...

Atoms for kids is an introduction video that helps students learn all about atoms. We answer questions like "What is an Atom?", "What is an Atom made of?", and "What do Atoms do?". We explore protons, electrons and neutrons and give a...

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

This video is on moles and how to convert between grams and moles. The speaker explains what a mole is, its significance in measuring chemical amounts, and the use of Avogadro's constant in determining the number of atoms or molecules in...

What the microscope did to unlock the secrets of biology, the ""chemiscope"" is intended to do, to revolutionize chemistry. The ultimate goal is to observe chemistry in the act, to see the making and breaking of bonds in real-space and...

Learn the basics about the shapes of simple molecules, when learning about properties of matter. In reality the shapes of simple molecules are 3-D molecules and should be visualised as such. Imagine now the central carbon atom surrounded...

Density Of Different States | Matter | Physics | FuseSchool Why is it easy to lift up a big inflated beach ball but much harder to lift a small heavy pebble? It is largely to do with density, the small pebble is more dense and the Big...

What does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot -- Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the...

This video provides an overview of alkenes, a type of hydrocarbon that contains a double carbon-carbon bond in their molecules. The video covers the structure and formulas of several alkenes, including ethene, propane, butene, and...

This video is a lesson on how to represent elements and compounds in terms of the atoms they can take. The video covers the definition of an element, the periodic table, chemical symbols, and formulas. It also explains how compounds are...

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on molecular-level structures.

In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...
