This Chem4Kids.com site explores the rate of reactions. Content focuses on forces that change the speed of reactions, and measuring rates.

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will apply the concept of conservation of momentum using action and reaction forces.

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

[Free Registration/Login Required] Learn about Newton's third law of motion, calculations in two dimensions, and the interaction of multiple objects in the context of a horse pulling a cart.

Activity on the Mexican Revolution in which students read the article provided, answer questions for discussion, and write an informed essay on why they think Villa or Zapata or both should or should not have become president of Mexico.

Lesson teaches about Marie Curie and Chemistry. Lab activities include making slime, elephant toothpaste, and snow, and also a balloon rise.

Students are give the opportunity to practice some action-reaction pair problems. Each example is self-checking for on-the-spot reinforcement.

The purpose of this activity is to demonstrate Newton's third law of motion - which states that every action has an equal and opposite reaction - through a small wooden car. The Newton cars show how action/reaction works and how the mass...

This multimedia site explores the Supreme Court reaction to affirmative action cases in university admissions policies. There are links to audio clips and various related articles.

In this activity, students will observe another aspect of a chemical change which is a change in temperature. In this reaction, students will experiment with an endothermic reaction.

Observe reactions that produce gases in this lab activity! Students observe chemical changes as they evaluate the amount of gas produced. This lab activity includes both student and teacher instruction sheets.

A lab activity where students observe a chemical reaction by creating a precipitate. In this lab, students will create soap scum by combining hard water with soap. Lab activity includes both student and teacher information sheets.

Students will complete a procedure to find the solution that has the greatest amount of acid by comparing the amount of the acids in different solutions. This lab activity compares the amount of acid in differents solutions in a...

Here's a full and understandable discussion of Reaction Rates and Equilibrium.

Young scholars learn why and how motion occurs and what governs changes in motion, as described by Newton's three laws of motion. They gain hands-on experience with the concepts of forces, changes in motion, and action and reaction. In...

This is a glossary entry for the term "Characterization" including a definition and the characteristics to be developed: Character's appearance, actions, thoughts, voice, and reaction from others.

This video is a professional development resource that explores student misconceptions about atoms, molecules, and chemical reactions. It also gives some pedagogical approaches for approaching these subjects. [10:12]

Through examples and practice problems, this interactive tutorial helps students understand the Law of Action-Reaction as it has to do with Newton's Laws.

Activity in which students investigate the Watergate Scandal and explore the concepts of impeachment, Executive privilege and presidential pardoning. Includes questions for discussion and small group work.

This site from the National Aeronautics and Space Administration provides fun information on bubble powered rockets. "Build your own rocket using paper and fizzing tablets! Watch it lift off. How high does your rocket go?"
