Everything we see and touch is made up of millions of tiny particles. This program is full of colorful examples showing the ways that matter is composed of particles. Vivid animations illustrate how matter consists of different types of...

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...

The video explains how the periodic table is arranged and how this arrangement highlights patterns in the chemical properties of elements. It covers the order of elements based on their atomic number, their placement in groups based on...

This video explains the differences between copper and helium, highlighting their properties as elements. It introduces the concept of elements as chemically pure substances that cannot be further simplified. The video also mentions...

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

In this video, the concept of mass number is explained, using the example of sulfur. The video also introduces the idea of isotopes, using carbon as an example, and explains how the atomic mass is calculated as a weighted average of the...

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...

In this video, the concept of elements is introduced, emphasizing that they are pure substances made up of only one kind of atom. Examples of elements like gold, helium, and aluminum are shown, along with their atomic...

By the end of this learning object, the student will be able to: Introduce the elements in nature.41826

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...

Early atomic physics - the development of the first ideas. The first ideas started with Democritus: atom is unsplittable. Then John Dalton Law of constant proportions. Avogadro: Molecular theory of gas laws. Prout's hydrogen weight...

The video discusses the development of the atomic theory, starting with Democritus' belief that matter cannot be infinitely divided. It then highlights John Dalton's contributions in the early 1800s, where he observed weather activities...

It defines an atom and tells about its discovery. It describes the characteristics of an atom.

We compare melting points of lead and tin to the melting point of their alloy, solder. By timing how long it takes samples of each to melt, we discover that the melting point of solder is actually lower than those of both lead and tin....

Learn the basics about what is an element? how is a mixture done? and what is a compound? Find out in this video!

There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life! Learn about these lesser...

In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

It's been said that your body contains billions of atoms from every famous person who ever lived. But is that true? And how do we know?<b<br/>r/>

One of the most famous elements in the periodic table doesn't really belong anywhere chemists would like to put it.

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...

For thousands of years, water was thought to be an element. That is, until some of the greatest chemists in the world managed to crack it open.

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

Mr. Andersen details the history of modern atomic theory.

Mr. Andersen describes atomic structure and tours the periodic table.
