Learners participate in a whole class discussion of ocean-floor structures and plate tectonics. They respond to prompts in a structured sequence that lead them to conclusions about the role of plate tectonics in the creation of sea-floor...

Students develop a sense of geologic ("deep") time and the ways in which Earth scientists construct the geologic time scale. They study he major events that shaped Earth, including the origin and evolution of its lithosphere, atmosphere,...

Students examine the origin of life on Earth and its evolution through geologic time by participating in a whole class discussion. They respond to prompts that lead them to conclusions about the interactions among the biosphere and the...

Students investigate Daisyworld, a very simple planet that has only two species of life on its surface - white and black daisies, and bare ground. They construct a Stella model of Daisyworld and perform guided experiments to explore the...

Students examine the influence of the end wall. They find a basin size and wind speed such that a given wall height is overtopped. Then, increase the wall elevation until overtopping stops. Students explain the difference in results.

Students calculate weathering rates from tombstone weathering data. Atmospheric (and precipitation) chemistry determines the rate of weathering for marble tombstones. They are shown data from a rural and an unrban cemetery, and are...

Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...

Students create a geologic map and cross-section of an area of horizontal sedimentary rocks, exposed in several locations. Map must include a complete key or legend with rock descriptions of the various formations.

Students participate in a JAVA activity to vary the seismic P and S wave velocity through each of four concentric regions of Earth. They match "data" for travel times vs. angular distance around Earth's surface from the source to detector.

Students describe and interpret images. They make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.

Fourth graders discuss life in a coral reef, and view photographs and a computer program about coral reefs. They design and create colorful watercolor, ink, and crayon drawings of coral reefs.

Third graders review the basic structure of a bilbliography and its importance in writing. They create a bibliography of materials used to complete a written report, and power point slide show and use the computer lab to create a final...

Tenth graders differentiate angiosperms and gymnosperms. In this biology lesson, 10th graders construct a musical phylogenetic tree from information they gathered on resource websites. They present their project in class.

Students explore the concept that different waterways support different organisms. After completing experiments, students predict what life-forms exist in each waterway in their area. They research how humans impact the habitat of other...

Students research selected Internet links to provide information about the characteristics and behavior of the bald eagle.

Eighth graders visit a local park to collect insects. They record the habitats, identify the insect and write a report including the kingdom, phylum, class, and order.

Students work together to identify and categorize objects. They have to identify the object on touch because they are blindfolded. They record their data and describe the objects once they can look at them.

Eleventh graders explore and compare Canadian biomes and investigate species at risk. They describe population growth and eco-regions in terms of climate and geography. They research and create presentations about the natural history and...

Learners research the characteristics of toothed/baleen whales in books and on the internet. The students participate in whale projects, quizzes, and activities on the internet sites provided.

Pupils visualize DNA from cells and explain the basis and importance of the Gram-stain reaction and to perform the KOH test equivalent.

Students study the physical differences between wetland and upland soils. They match colors to the different levels of the soil after digging holes. They create soil color charts and chart the texture of the soils.

Fifth graders research the earthworm and write a one paragraph report on its anatomy and habitat. They learn about worms and how to dissect them through Video Streaming and virtual dissections, along with actually dissect a worm as...

Students analyze how studying garbage relates to methods of archaeology. They examine garbage to determine things about their culture and relate that to prehistoric peoples.

Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.
