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...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Students experiment with solids and liquids. In this mixtures of matter lesson, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by having...

Students determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Students determine the heat required to melt one mole of ice using hot water and ice...

Young scholars explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Young scholars will then work in the lab to identify changes at different stations prior to...

Seventh graders research about the effect of climate on different ecosystems. In this life science lesson, 7th graders present their research by creating a poster, infomercial, skit or song. They discuss how organisms adapt to climate...

Students focus on the production of maple syrup in Northern New England as they study the effects of climate change. They investigate other environmental factors on the forests of Northern New England.

Fifth graders observe and identify the differences between chemical and physical changes. In small groups they mix different substances together in glass beakers, and identify which had a chemical change, supporting their statements...

Fourth graders investigate the ecosystem and how forests are disappearing.  In this environmental protection lesson, 4th graders analyze the changes in their school for 2 weeks.  Students practice identifying trees, birds, and...

Young scholars identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.

Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Review and restate the law of supply. In groups, learner practice reading a supply schedule and supply curve. They explain how and why changes in the cost of production change supply, then work together to complete practice problems to...

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...

Pupils examine the greenhouse effect, as they determine how moisture in the air affects the diurnal temperature range. Their investigation help them to explain different climatological regimes of both the Southern Great Plains and the...

How can climate change affect our water supply? Have kids read a passage about the water cycle and water conservation, which includes six questions that challenge them to use context clues.

Students examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.

Students discuss acceleration and deceleration and participate in brief demonstrations of the Second Law of Motion. They apply the law to a metal balance toy and a plastic balance toy by applying the same force then with different forces.

The title is a little deceiving since only one of 17 slides is dedicated to the function of leaves, while the rest is dedicated to the structure. Both internal and external structure is taught with accompanying diagrams. If you are going...

Students examine the different changes in matter.  In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

Getting kids thinking about climate change now, will hopefully push them into action when they become adults. Young environmentalists discuss the evidence and causes of climate change seen in the state of California. They brainstorm ways...

Learners recognize how the climate of the Hudson Valley has changed since the last glaciation. They explain these changes using a reconstruction of the land use changes in the Hudson Valley composed of confetti, Ziploc bags and other...

Students discuss what heat is and how it travels. They discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
