Conservation of Mass Teacher Resources

This short video simply explains the Conservation of Mass with graphics that show the atoms being conserved in pictures of balanced equations. The connection between mass and energy is explained and Einstein's energy equation is mentioned.

Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

New things are created all the time while others disappear, does the Law of Conservation of Mass mean your drone might be made out of dinosaurs? The 16th video in a series of 29 begins with a timeline of scientific discoveries related to...

There is no narration in this video, just footage of a hand performing a chemical reaction set to magic-show-style music. Starting mass is shown in text. Solutions are mixed so that a precipitate forms, and then ending mass is shown....

Does matter ever just go away? Find out with this entertaining video that dives into a sweet investigation that involves cake and sweet drinks! Super scientists gain insight about the physical changes from chemical reactions and...

For this conservation of mass worksheet, students experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the experiment...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

In this conservation of mass worksheet, students design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

In this conservation of mass worksheet, students balance 4 equations and identify the products, the reactants and the kind of reaction. Students then answer 5 questions about the conservation of mass.

Extremely short, this video is a computer animation of a double-pan balance with zinc and sulfur atoms on each side. The synthesis reaction between the two occurs, with the new zinc sulfide molecules. The balance is still balanced. This...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation. The...

Four lessons can be found in this chemistry resource. A pretest is provided, and then young chemists explore the law of conservation of mass in chemical reactions. Then they learn about the laws of definite and multiple proportions. In...

In this law of conservation of mass worksheet, students solve 10 reaction problems by determining the mass of a reactant or product.

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in mass.

Try creating something out of nothing—it's not possible! Scholars watch an engaging video, the seventh in the Crash Course Engineering series, to learn about the Law of Conservation of Mass. The video also covers the accumulation,...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...

In this early atomic theory learning exercise, students answer 4 questions about the Law of Definite Proportions, the Law of Conservation of Mass and Dalton's Laws. Students are given 5 statements to determine if each true statement...
