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...

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...

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 Discussion incorporates historical references as well as formulas.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.

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 plan is used early in the Chemistry course. The students love it....

What are serious scientists are saying about bosons? This site provides text correspondence between two scientists in question-answer format. Shows why bosons are so important in particle physics.

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.

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 good explanation of basic quantum theory.

An introduction to the building blocks of matter, and the forces that interact among them. There is also brief discussion of antimatter and the standard model. This resource has numerous links to additional physics topics.

Help the Mummy build a rollercoaster to entertain the Atoms Family monsters by investigating the concepts of kinetic and potential energy.
