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...

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

High schoolers examine "masterpieces" and mass-produced objects as they discuss humankind's inventiveness and creativity. They also analyze the role of problem solving in the creation of masterpieces and mass-produced items.

High schoolers 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...

Young scholars investigate mass-mass relationships in the lab. For this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. Young scholars use the...

Students investigate mass-mass relationships using potassium carbonate and hydrochloric acid. In this mass-mass relationship lesson plan, students measure a certain amount of potassium carbonate and determine how much hydrochloric acid...

Study the difference between mass and weight. Your math group will compare the weight of an item to the amount of space that it uses. They'll then use conversion factors to find the difference between kilograms and pounds. Essential...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Youngsters test magnetic strength by measuring the mass of paper clips that they "hook" with a magnet. Your first and second graders should love the hands-on activities associated with this plan. The reproducible materials are quite good...

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...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Sixth graders comprehend the difference between mass production and custom manufacturing. They have a basic understanding on how items go from a raw material to a manufactured finished product. Students have an understanding of the...

Students examine the suggestion that the subjective experience of everyday life and sense of identity has changed in America in recent years. In this post-modernism and mass culture lesson, students engage in 4 multi-step exercises that...

Middle schoolers explore geometry by completing a physics activity on-line. For this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

World War II was not just waged in Europe and Asia; the home front was key to Allied victory. Using newspaper clippings from World War II and a map, scholars plot out wartime production in the United States. After that, class members...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Students explore physical science by conducting a measurement experiment. In this mass lesson, students identify the differences between mass and weight and define a list of other vocabulary terms. Students utilize electronic scales and...

Students support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open or...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Students conduct experiments to determine if length, mass, or starting angle has any effect on the rate of a pendulum's swing. They also conduct an experiment online to determine if gravitational force plays a role in the swing. Groups...

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...

Why is it so difficult to make two solid compounds react? Investigate the concepts of particle collisions and rate of reaction using a quick demonstration. The colorful experiment features two plain, white solids combining to form a...

Students identify the geometric mean of their data. In this statistics lesson plan, students collect data and graph their findings. They identify the mean, range and mode.
