A simple tutorial that includes interactive activities and videos to introduce the law of conservation of mass.

Everything in our universe has mass- from the smallest atom to the largest star. But the amount of mass has remained constant throughout existence even during the birth and death of stars, planets and you. How can the universe grow while...

From the Glenn Research Center at NASA, read about the law of conservation of energy. Included are formulas and many links to key terms.

This resource includes videos, interactives, and additional resources to help students understand the law of conservation of mass and how to balance chemical equations.

Article explores the key points of Dalton's atomic theory and the laws of conservation of mass and constant composition. Which points do we still use today?

A collective which looks at mass and energy. Identify the forms of measurement and how to convert them as well as scientific notation. Practice application with homework problems.

From a chapter on Linear Momentum and Collisions in a Physics textbook. This section of the chapter discusses collisions in two dimensions, what point masses are, how to calculate the conservation of momentum, what happens when two...

This site provides a set of four Physics problems dealing with the conservation of momentum principle.

An interactive simulation that teaches about periodic motion, simple harmonic motion, and conservation of energy. Observe one or two pendulums to determine how the swing is influenced by the length of the string, the mass of the pendulum...

Students conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet, videos...

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when...

A collection of experiments, projects, and articles that will help students understand particle collision and mass, kinetic energy, magnetic field, the Large Hadron Collider, and detection of the Higgs particle.

[Free Registration/Login may be required to access all resource tools.] Students explore mass relations between reactants and products for a given chemical process, and practice balancing chemical equations.

Resource investigates the beliefs of Dalton's atomic theory which consists of four parts. Which points do we still use today, and what have we learned since Dalton?

Students learn about the Newtonian mechanics principle of conservation of angular momentum and the application in the quantum mechanical world.

Young scholars learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of...

In this activity, students carry out a chemical reaction in which two reactants (baking soda and hydrochloric acid) produce three products (sodium chloride, carbon dioxide gas, and water) and determine that the solid product (sodium...

Electric vehicles are in use today but pose challenges to widespread distribution. One of the challenges is to develop a battery that can hold enough energy for longer trips. Various solutions are being tried but mass marketing of this...
