High schoolers examine how artists structure their compositions to convey a sense of symmetry and balance. They analyze various paintings, identify objects and figures in the paintings, conduct Internet research, and evaluate paintings.

Students examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.

Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.

Fourth graders construct mini-ecosystem, pollute the ecosystem, observe, collect, and record data on the effects of these pollutants on their ecosystem, organize data on spreadsheets, create graphs, and design presentations to share with...

Students design a structure capabl;e of holding a textbook. They demonstrate that the weight of a textbook is offset by the normal force exerted on the book by the structure.

Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...

Students examine the different types of market structures. They analyze these structures using diagrammatic representations.

Students examine how motion capture technology allows computer based animators to design realistic effects in animation. They study how the center of gravity contributes to animation and how to use the center of gravity to write an...

Third graders read a thermometer with accuracy, record observations and data, and infer conceptual meaning. They integrate mathematical charting and graphing skills to organize their data. They explore what happens when they touch or use...

Learners determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

Students navigate and analyze information about the presentation of a disease during a class discussion. They document and share their analysis of information in a class discussion in order to describe a variety of disease origins.

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 view an image from the Metropolitan Museum of Art and identify the focal point of the painting. They discuss symmetry and balance as it pertains to the images. Students use the Student LaunchPad (linked to this lesson) to help...

Students choose a current environmental issue and research historical conditions as well as present conditions. They assess the changes in ecosystems, populations of specific species, air quality, or any other aspect of an ecosystem.

Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

For this evolution crossword worksheet, 7th graders complete a crossword puzzle about evolution. Students read the definitions to fill in the puzzle with evolution terms.

Students encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.

Fourth graders explore the concept of economic goods and bads, and scarce items as it relates to the factors that affect our economy. In this supply and demand lesson, 4th graders are introduced to vocabulary that pertains to supply...

Students conduct observational studies of three ecosystems by visiting the Web World Wonders website. They gather data, compare/contrast the information, and decide on the establishment of a nuclear power plant at one site over the others.

Students examine the steps of the rock cycle. They describe what happens to the rocks in each of the stages. They participate in a rock cycle game to help them with the steps.

Middle schoolers examine global warming, and the greenhouse effect. They determine the changes that happen and the adaptations that need to be made because of these occurrences. They look at the occurrence and effect of these phenomena...

Students research the biology and natural history of the cougar. Students conduct Internet research to determine how cougars have been protected by humans and how it is affected by human decisions. Students write about reconciling...
