Students examine the economic, health and environmental risks of being a one-crop country. They explain the risks of relying on one crop. They also identify the factors that resist change.

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Students 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...

Young scholars recognize how the climate of the Hudson Valley has changed since the last glaciation and be able to explain these changes. They reconstruct the paleoclimate of the Hudson Valley.

Students consider the development of different societies. In this environmental building lesson, students consider local resources and how societies choose to use them. Students use their findings to design a 'green' building for use in...

Students study how to create a compost heap. For this composting lesson, students create a compost heap. Students write an essay describing the process.

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

A set of PowerPoint slides supports a lecture or class review of weathering and erosion. Viewers learn the definition of each and examine various photos for evidence. Erosion is further depicted as caused by wind, water, and ice....

Students explore the conditions needed to grow Texas Blue Bonnets. In this Blue Bonnet planting lesson, students recognize the differences in Texas Blue Bonnet. Students record their findings in a graphs and analyze their results.

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Students build and test structures that can best withstand earthquakes. They create their structures from playdough, cornstarch, grape-nuts and popsicle sticks and place their structures on a "shake table."

Sixth graders discover the problems that early Mesototamian farmers faced while developing agriculture in the land between the Tigris and Euphrates Rivers. They design a working model that solves those unique challenges.

Students demonstrate the interrelationships of animals and plants. In this ecology instructional activity, students discuss the things plants and animals need for survival and study the glacier food chain. Students simulate the web of...

Students develop an understanding of our planet as a system by designing a very-long-duration space mission in which the life-support system is patterned after that of earth.

This clever lesson combines elements of geography, art, literature, and storytelling. Pupils take a close look at the six geographical regions of Arkansas, and pay close attention to Crowley's Ridge - which is one of the six. In groups,...

Students investigate Earth and its resources. In this Earth, space, and nature lesson plan, students collaborate to design presentations on the Earth, its cycles, and how humans have impacted the planet. Images, diagrams, and background...

Both GPS and GIS are now used regularly in agricultural careers. Explore the new technologies that require higher education for those interested in agri-science careers. Upper graders examine how agriculturalists use new technologies by...

After reading a short and informative paragraph on animals and their environments, learners look at pictures of four animals, and write a short description of how each one has adapted to its environment. A suggested activity is that each...

Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model...

Purifying air and water, providing soil in which to grow crops, and moving water through its natural cycle are all services an ecosystem provides that benefit humans. Lesson four in a series lets learners explore and discuss the value of...

Students demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

The nitrogen cycle is the focus of a well-designed science lesson plan. In it, learners see that plants and animals produce waste products and decompose after death. Many of the waste products include nitrogen which is absobed by other...

What a great way to start a recycling lesson! Introduce your students to the dung beetle! They will get a kick out of "nature's perfect recycler," when they learn about the  scarab beetle's way of life: eating dung and rotting...

Students observe and listen to nonfiction books about the life cycle of pumpkins. They practice early reading skills in a shared reading related to pumpkins. They observe the life cycle of a pumpkin including growth and decay.
