Did you know matter is made up of atoms? In this article learn about the smallest unit of matter called the atom.

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

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)...

Investigate the changing states of water as you help Steve stay alive while in the Arctic. Includes background information about changing states of matter and about the water cycle, as well as a quiz.

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.

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.

This site from the Coalition for Plasma Science provides a short, interesting paper outlining the relative importance or precedence of plasma compared to the other states of matter.

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

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.] 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.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2016 with one-half to David J. Thouless of University of Washington and the other half to both F. Duncan M. Haldane of Princeton University and J....

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."

This teaching box is filled with educational resources that help students explore the science of, and solutions to, air pollution.

Under the heading, "The Infrared Hunter" this site examines specific details of an image displaying the Orion nebula along with several other nebulae. In describing the image, the text at this site ends up examining subject matter...
