Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

This live-action video program is about the word Mechanics. The program is designed to reinforce and support a student's comprehension and retention of the word Mechanics through use of video footage, photographs, diagrams and colorful,...

Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really...

What's the difference between a physical change and a chemical change? What are elements, compounds, pure substances, and mixtures? So many definitions to learn! Don't worry, Professor Dave will take you through the details.

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...

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...

We've established that the basic unit of life is the cell, and that the simplest forms of life are just one cell. The earliest unicellular organisms were prokaryotic, and there are many prokaryotic organisms still around today, including...

Atoms don't just appear and disappear into thin air, you silly goose. What are you, a magician? When we have a chemical equation we will have to balance it. Here's how to do it!

Atmosphere Set: 2. This clip explains how the ozone layer is formed in Earth's atmosphere. The role of ozone is described and the destructive effects on the ozone layer of chlorofluorocarbons (CFCS) is explained.

We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand...

Almost all life either directly or indirectly depends on one of the most important biological processes on the planet - photosynthesis. Through easy-to-understand graphics and colorful animations, the complex chemical process of...
