Students experiment to understand the basic concept of polymerization and to understand the dissolution theory. Student experiment with polymers to understand its behavior and the mechanical behavior of polymer networks.

Sixth graders, in groups, examine how humans have a tenuous position as part of an ecosystem.

Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Third graders measure the heat created at each center.

Learners work together in groups to participate in a trading game. They are allowed to trade with different people in each round. They discover free and restricted trade.

Pupils inquire into how the center of mass is the key factor in designing cars. They construct an oddly shaped object and determine its center of mass. They find that engineers are able to predict how objects will behave while they are...

Students explore bioethics. They discuss the traditional ethics of human conduct and man's relationship with nature. Students identify ethical dilemmas. They discuss ramifications of economic and ecological concerns with bioethics.

Students explain and understand the circulation of air in the atmosphere. They identify that energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects. ...

Students participate in this program that heightens their awareness and curiosity of nature as well as their sense of adventure and exploring new surroundings. They identify and choose an object from nature after exploring it with other...

Students examine the concepts of balance.  In this balance and gravity lesson students view a demonstration of a leaning tower and see how to find the center of gravity.

Students examine the relationship between temperature and brightness.  In this astronomy lesson students will correlate the evolution of stars to the HR diagram plotted. 

Students compare the three theories used tp interpret fossil records. For this earth science lesson, students create a production of a televised debate. They collaborate with group members to generate relevant questions about the topic.

Learners investigate what a system is in the scientific world. They watch a video of the Stellar seals of Alaska and develop clues as to why the seals are leaving. They discover through the clues they discover, how the components of the...

Students examine the problem concerning the evolution of seed color in pinto bean plants "How does natural selection change the frequency of genes or traits over many generations"? Students work in teams to design an experiment that...

Learners estimate the size of a sea turtle nest, or clutch, that contains about 120 eggs. They decide what type of container that they are familiar with that could hold a complete nest or clutch. Finally, students calculate the volume...

Students study sea turtles and the concept of temperature-dependent sex determination (TSD). Using a specific set of temperature data, they determine the probable sex of a nest of sea turtle hatchlings and then determine the overall...

This lesson is meant to give an introduction of equilibrium constant expressions to the students. They are given balanced chemical equations and then asked to write the equilibrium constant expressions for them. The students will be...

For this lesson summary review and remind yourself of the key terms and graphs related to a short-run macroeconomic equilibrium. Topics include how to model a short-run macroeconomic equilibrium graphically as well as the relationship...

This game helps students to understand the concepts of changing supply, changing demand, and equilibrium price, as the price of bags of ice changes after a hurricane has swept through a community.

Analyze some step-by-step examples of shifting supply and demand curves. This resource is designed for students who are taking a college-level microeconomics course.

In this lesson summary review and remind yourself of the key terms and graphs used in the analysis of markets. Topics include how to use a market model to predict how price and quantity change in a market when demand changes, supply...

The concepts of stability and equilibrium are introduced while students learn how these ideas are related to the concept of center of mass. They gain further understanding when they see, first-hand, how equilibrium is closely related to...

In this lesson, students use the fossil record to understand the topics of speciation, punctuated equilibrium, and gradualism. Students arrange fictitious animals' fossils by age based on appearance to create a fossil record.

This lesson will help students to understand how markets are created by the interaction of buyers and sellers, what demand and supply are, what equilibrium price is, and how demand and supply interact with price changes.
