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 Discussion incorporates historical references as well as formulas.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.

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.

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...

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...

A detailed overview of global climate change, with explanations of Earth's climate change, the carbon cycle, ecosystems, and greenhouse gases, and how the movements of matter and energy impact on climate. All information is reinforced...

This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.

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...

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.

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

This introduction to chemistry class reviews some major concepts to help prepare students for a high school chemistry course.

We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwatsheds light on the phenomenon by examining the nature of...

As students begin their study of states of matter, this hands-on activity demonstrates how the interaction of a solid and a liquid can reverse the initial state of each material.This lesson plan was created as a result of the Girls...

[Free Registration/Login may be required to access all resource tools.] Looks at how atmospheric circulation cells affect the climate of regions.

[Free Registration/Login may be required to access all resource tools.] Describes some factors that lead to long-term climate changes.

[Free Registration/Login may be required to access all resource tools.] How close a region is to the ocean affects its climate.

Students use a dichotomous key to sort materials into natural and man-made and sort further using the adjectives rough and smooth; this activity builds both science and language skills as students classify materials and build deeper...

Looks at how Newton's three laws of motion apply to an analysis of the forces being exerted when playing football.

A good explanation of basic quantum theory.

From ABC News in Science, Irene Klotz's article explores the abundance of black holes in the Cosmos currently at work "devouring nearby stars and other matter."
