On this site, find a variety of materials to help young scholars 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...

[Free Registration/Login may be required to access all resource tools.] The law of conservation of mass and an example.

Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.

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.

Learn about the conservation of mass and energy as it applies to different living systems.

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.

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

Learners 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...

[Free Registration/Login may be required to access all resource tools.] Explains Law of conservation of mass and why chemical equations must be balanced.

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.

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.

This article helps students understand and apply Newton's third law and the conservation of momentum.

This lesson explains the law of conservation of mass within chemical reaction with audio and quiz questions.

This lesson explains the law of conservation of mass within chemical reactions. It is 4 of 4 in the series titled "Conservation of Mass."

Explains the Law of Conservation of Mass, or Law of Conservation of Matter, and gives two examples for it.

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

[Free Registration/Login may be required to access all resource tools.] In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an...

Atoms and molecules come together to create matter. What happens to the weight of matter when it is frozen? Can matter be destroyed? Check out these activities to clearly understand how this works.

Explore balanced chemical equations in this tutorial. Tutorial includes videos, interactive activities, and practice to help students understand balanced chemical equations and the Law of Conservation of Mass.

Learn how mass is conserved in physical and chemical changes.

Second graders explore the concept of law of conservation of mass.

Explore the concept of matter in this Spanish-language encyclopedia entry. This site features the properties of matter, the Law of Conservation of Matter, and other important features of matter.
