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

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

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...

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?

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...

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

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.

[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.

Students 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...
