Students conduct an experiment to simulate an oil spill and identify the characteristics of oil in water. They evaluate the effectiveness of various cleanup methods. They discuss the how to clean up an oil spill, and what causes oil...

Students create a water transportation device powered by wind. In this wind power lesson, students research transportation concepts after reading the poem "Sea Fever" by John Masefield. Students design the fastest sailboat they can...

Students examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.

Students explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.

High schoolers read primary source documents and identify several kinds of service projects conducted by Peace Corps Volunteers; young scholars identify criteria used by the Peace Corps for conducting service projects for the common good.

Students determine potential sources of major air pollutants, explain how acid rain is generated and how it affects the environment, discuss global warming, and explore protective role of ozone and cause of ozone layer thinning. Lessons...

Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.

First graders are introduced to the topic of researching by the librarian. Using a worksheet, they use various sources in the library to choose one animal from various groups. They complete a fact sheet on each animal and report their...

Pupils use topographic maps to identify parts of rivers. In addition, they discover gradient and predict changes in the channels caused by variations in water flow. Other activities include sketching a river model with a new channel...

Students examine the carbon cycle while identifying its sources, sinks, and release agents. Using magazines and newspapers, groups of students design collages illustrating the carbon cycle. Finally, they write responses to several...

Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...

Seventh graders consider different cultural viewpoints. In this Kansas history lesson, 7th graders examine the depletion of buffalo as a contention point between Native American and European settlers. Students read diary entries to gain...

Students investigate the concept of American freedom with the use of primary sources of images in order to derive meaning. The images are used to inspire research and writing about historical scenes. The writing and analysis of the...

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

When studying the slave trade in early American and world history, use this document to expose your learners to the abhorrent conditions that existed on slave ships. Read through two first-person accounts of the enslavement process,...

Fourth graders construct their own aquifer. They discover how water travels underwater and identifies sources of underground pollution. They record their observations and discuss the results.

In this watershed worksheet, students read through related definitions and complete 17 short answer questions about deposition and erosion in the Hudson River.

Students write a report about energy use. In this conservation lesson, students interview adults about their use of renewable and nonrenewable energy. Students synthesize this information and write a report from the point of view of a...

Students collect water samples from a local source, test it, filter it and identify the materials suspended in it. Students disucss the possible sources of sediment in their watershed.

High schoolers explore the sources for recharge and discharge of groundwater. They research the connection between surface water and groundwater. Students construct a model of an aquifer and explore recharge and discharge of the aquifer.

Students observe yeast fermentation using different energy source. In this chemistry lesson, students measure the gas collected in the balloon. They upload their observations on the internet so they can share it with kids across US.

Students collect water samples from around your home and school, check the pH level of each water sample, and record the pH levels in a chart that looks something like this:

Students study how a geologist examines a hazardous waste spill using an actual site. They use site data to map the spill, find its source and determine how fast the spill is spreading.

Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.
