Dalton's Playhouse is an interactive concept simulation meant to convey fundamental concepts in chemistry, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Students investigate whether or not chewing gum should be considered eating using the law of conservation of mass to reason that the portion lost of the original mass of gum must be swallowed.

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

In this human behavior science fair project, the student will learn about Piaget's developmental stages and the Theory of Conservation. The student will investigate the age at which children understand the equality of numbers and mass....

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.

Learn how mass is conserved in physical and chemical changes.

This Kahn Academy tutorial helps students understand the principles of conservation of energy and mass. [10 min, 6 sec]

Law of conservation of mass: No atoms are created or destroyed in a chemical reaction. They just join together in a different way than they were before the reaction, and form products. This means that the total mass of the products in a...

Students analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-PS1-5: conservation of atoms in reactions.

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

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...
