Educational site provides activities for teachers to use to teach the states of matter as well as provides videos to supplement instruction.

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

Instructional module focusing on density as a physical property of matter. Discussion incorporates historical references as well as formulas. Site also includes an interactive practice quiz and links relating to the topic.

In this science fair project, use a globe and a heat lamp to investigate how the angle of the Sun affects global warming. This project includes the objective, background questions, a list of all the materials you'll need, and the...

If you know or calculate the field of view for your camera, you can use it to measure distances and the height of almost anything. It's all a matter of basic trigonometry.

No matter what your favorite card game is, we all wish we could use psychic powers to draw the card we want on our turn. You may not have psychic powers, but you might have the power of probability on your side. Do this experiment and...

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the...

Sure you understand what makes submarines cool, they allow us go underwater and explore the sea! But understanding how they function is a completely different matter. This lab will help you investigate how submarines dive and surface by...

Learn about the three phases of matter, and how the addition and removal of thermal energy (also known as heat) affects them.

What's the Matter? is a guided inquiry lesson on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson: (a) concentration game for definitions and (b)...

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This lesson is used early in the Chemistry course. The students love it. This...

This tutorial helps students understand the Kinetic Theory, which explains the effects of temperature and pressure on matter as it goes through phase changes.

Students are given a scenario for this lesson where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an experiment with...

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on dark matter. Review questions are included at the bottom of the study guide.

Students learn about biogeochemical cycles that recycle matter on Earth.

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare...

The chemical change of matter is illustrated in this lab experiment when spaghetti is placed in a solution of baking soda and vinegar. Watch the spaghetti rise to the surface and sink again once the gas is released.

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

A chemistry tutorial highlighting historical development of the atomic theory of matter and the periodic table of elements.

In this science activity, you will find out how much of a compound is too much to dissolve.

These resources have been collated to National Science Standards, and include lesson planning ideas.

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which...

This illustrated essay from the NOVA Web site explains why the atomic structure of a diamond slows down light and produces a sparkle more brilliant than from any other colorless substance.
