Students discuss and analyze factors affecting U.S. foreign policy toward Liberia. They role-play various groups during 1900 who were concerned with the relationship between United States and Liberia as a "colony"

Students explore the role of chemicals in the pollution and destruction of ecosystems. They research factors that affect ecosystems and the methods being employed to counter them. In addition, they choose one water ecosystem that has...

Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...

Students examine the roles that natural events (such as droughts), population growth and other human factors play on land use and food supply.

Students create flubber glaciers. In this glacier dynamics lesson, students experiment factors that may affect glacier speed. Factors include slope, ice temperature, and basal conditions. Students develop hypothesis, conduct experiment,...

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Students explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further...

Students determine the relationship between bone length and height. In groups, they are told the race and gender of the individual and discuss how this affects height. They measure the lengths of the bones in metric measurements and...

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

Students analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...

Middle schoolers explore distance-time plots. In this algebra instructional activity, they will investigate how different types of motion affect the distance-time plot.

Students examine how the countries of the Middle East were created. They explore the influence of various political and geographic factors in their creation. They list the things they should consider in deciding how to draw new borders...

Young scholars investigate the factors affecting climate using Live Access Server. In this geography lesson, students graph atmospheric data using Excel spreadsheet. They compare and contrast temperature, precipitation and water vapor of...

Students develop an understanding of what a reaction is and factors that affect it. They are introduced to: reaction mechanisms, reaction rates, reaction order, factors affecting reaction rates, Le Chatelier's Principle and Equilibrium.

Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.

Fifth graders use captured portions of the Internet ("mininets") to perform research into climate. They create graphs of the data recorded using latitude as the independent variable and temperature as the dependent variable.

Students analyze the Greenhouse Effect and the science of greenhouses. In this global climate instructional activity, students read background information about the 'greenhouse effect' and define 'albedo.' Students examine pictures of...

The final lesson in a two-part series prompts scholars to create newspaper articles and succession events. Applying their knowledge of the ecosystem and the past examples of succession, they predict what will happen in the future...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

In these multiplication worksheets, students examine the use of the commutative and associative properties. They use the communative property to find the product in the first 30 problems. They read about the use of the associative...

Learners examine global issues centered around HIV and AIDS. In this health science lesson plan, students compare and analyze public health measures and factors that affect the treatment of HIV/AIDS. They examine the role of...

Ecology explorers or beginning biologists view a time-lapse film of decaying strawberries. They discuss how decomposition occurs and what factors might affect the rate of decay. Alone, the lesson plan is lacking engaging attributes....

Students investigate many of the factors that affect water quality. They take measurements and water samples at a local stream and evaluate the health of their community's watershed. They write a report detailing their findings.

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...
