Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

Review matter and atoms in this Jeopardy-style game.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Antimatter, the charge reversed equivalent of matter, has captured the imaginations of science fiction fans for years as a perfectly efficient form of energy. While normal matter consists of atoms with negatively charged electrons...

A resource provided to Grade 8 teachers to address the School District of Philadelphia's Core Curriculum on the topic of Matter. It covers properties and states of matter, elements, compounds, mixtures, atoms, and the periodic table....

After watching this simulation, students will be able to describe characteristics of the three states of matter. They will watch as atoms and molecules change between solid, liquid and gas phases.

In this interactive activity from ChemThink, students will take a closer look at atomic structure, properties, and behaviors. Includes background reading material and discussion questions.

Created to teach students of the 21st century, SOPHIA is bringing matter straight to your fingertips. Become the commander of your own learning experiences as you take part in this interactive tutorial. [1:02]

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...

Everythingin the universeis either matter or energy. All matter is made of combinations of about one hundred basic building blocks, the chemical elements on the periodic table. Going a step further and breaking these elements down to...

A video and a short quiz on the parts of an atom, the periodic table, and molecules.

This site provides an illustrated and animated story that seeks to answer several questions. What are atoms made of? What is keeping a nucleus intact? What happens if you try to separate two quarks? Are quarks fundamental?

Find out the basic characteristics and main properties of all matter.

Discusses the interaction between light energy and atoms of matter. Explains Einstein's photoelectric effect and discusses its application to lasers. Includes an interactive Java applet depicting the interaction between a photon and an...

This Study Card stack enables students to review the concepts of matter, the kinds and classes of mater including atoms, molecules, elements, compounds, pure substance, and mixtures.

[Free Registration/Login Required] Discover the composition of matter and the relationship between matter, atoms, and elements. Students will learn the differences between elements and compounds, and how molecules are formed. Chemical...

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

Atoms and molecules come together to create matter. What happens to the weight of matter when it is frozen? Can matter be destroyed? Check out these activities to clearly understand how this works.

Uncountable times every day "with the merest flick of a finger"each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the...
