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...

It may take up less space, but the mass stays the same. Tackle a common misconception about conservation of mass using a hands-on activity. Learners measure the mass of substances before and after melting, dissolving, and undergoing a...

What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

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...

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 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.

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Twelve pages of mostly multiple-choice questions comprise this comprehensive New York Regents physics exam. It covers an entire year's worth of physics curriculum and requires about three hours for completion. Review the questions to...

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

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

Students gain an understanding of matter in all of its phases. In this science lesson plan, students further their knowledge of the laws of conservation of mass, the loss in mass can be accounted for, when the gas is allowed to escape...

The third instructional activity in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Students investigate the Law of Conservation of Energy and the relationship between heat and temperature. In this heat energy and chemical changes lesson, students observe a candle heating a paper cup of water and make predictions about...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...

Young scholars investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions...
