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...

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....

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...

An educational activity 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. 

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...

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...

Young scholars 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...

Students discover the law of conservation of mass though experimentation.  In this chemistry lesson, students experiment with acid - base indicators to determine the presence of carbon dioxide. Students complete the labs with...

High schoolers 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...

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...

Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

Students experiment with the bounce of balls on various surfaces. For this physics lesson, students use various surfaces to bounce balls to study the momentum. This hands-on activity with the concepts of elasticity of surfaces which is...

Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...

Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Students observe what happens to water as it goes from a solid to a liquid.  In this exploratory lesson plan students gain an understanding for the water cycle while working in groups observing what happens to water as it changes...

Students examine how ice changes state and when  its volume changes.  In this mass lesson students complete a lab that shows them how waters volume can change. 

Young scholars experiment with different types of metal by dipping them in boiling water and cool water and recording temperature changes in the water. By doing this, they find the specific heat of the metals.

High schoolers differentiate the three states of matter. In this chemistry lesson plan, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Students explore the Law of Conservation of Matter using effervescent tablets.  In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...

Students explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Young scholars, using wood blocks and model boats, investigate how the shape of an object affects friction it encounters as it is drawn through a towing tank.
