This program makes the Modern Periodic Table come alive to students. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional...

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 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. ...

Have you ever been to a Demolition Derby? Then you have an idea of how molecular collisions happen. In this episode, Hank talks about collisions between molecules and atoms, activation energy, writing rate laws, equilibrium...

The video is a lecture on organic chemistry, introducing key concepts such as hydrocarbons, functional groups, homologous series, and isomerism. The speaker explains how organic molecules can be represented in different ways, using...

The video is about covalent molecules, their properties and behavior. The video then goes on to discuss polymers, which are formed by the reaction of monomers with a C-C double bond. The video also discusses giant covalent structures,...

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...

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

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...

What is the difference between a molecule and a compound? What are the main types of chemical bonds? In this video, we will be answering those questions and more.

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...

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!

As we construct more complex organic molecules, it can start to feel like decrypting a complex code. Organic synthesis takes simple starting materials, and turns them into complex structures, and reverse engineering can help us figure...

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.

Beyond molecules and atoms, how far down can we see below the wavelength of visible light? What is the smallest possible scale in the universe?

By the end of this learning object, the student will be able to: Describe the properties of molecules.17353

Element and compound

Upon viewing the Investigating Mixtures, Solutions, Elements, and Comnpunds video series, students will be able to do the following: Understand that everything we see, touch, and even things we can't see are made up of matter. Understand...

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...

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...

Atoms can (and do) bond constantly; it's how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond. From...

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...
