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...

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.

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...

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...

Concept animation compares molecular movement of solids, liquids, and gases.

Five exemplary chemistry lessons about the three states of matter complete with handouts and animations.

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.

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

Build elements and molecules using neutrons, protons, and electrons. Choices include helium, carbon, oxygen, aluminum, water, and salt.

[Free Registration/Login Required] This flipchart introduces fifth graders to compounds and molecules. It is part of a large unit on matter. Key concepts include compounds, molecules, and chemical formulas. Opportunities for student...

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

[Free Registration/Login Required] Explore the composition of air and learn about the different atoms and molecules that we breathe every day.

In this activity, students will prove the theory that matter is made up of tiny particles called molecules. This experiment will show that these "invisible" molecules are always moving and leaving invisible spaces in between.

See how gas, liquid, and solid molecules react to external pressure in this simulation. Also see a model of intermolecular motion through elliptical particles.

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...

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

Kid's learn about the science of the molecules. Tiny chemistry and compounds of atoms and elements make up all matter.

[Free Registration/Login Required] This flipchart is a guided activity to help students compare different types of matter: atoms and molecules, elements and compounds, mixtures and solutions. It corresponds to Virginia science SOL 5.4.
