Conservation of Mass
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...
Science 4 Inquiry
Maintaining Mass
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...

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