Students calculate the area of grasslands needed to support a small pride of lions. They also identify food web links in an ecosystem and trace the energy pathways in an ecosystem.

Learners are introduced to the geological development of the state of Indiana. Using the internet, they visit the U.S. Geological Survey and locate the earthquake zones in the state. In groups, they locate and identify the energy...

Students assess the positive and negative affects of humans on the environment. The lesson explores ways in which individuals and societies can reduce the negative impact on the environment. By taking a "waste walk" around their campus,...

Students observe the effect of light on plants. They illustrate the exchange of gases between the atmosphere and the plant. Students see that plants are part of many natural cycles. They investigate how green plants use the sun's energy...

Students determine the effect of the earth's tilt on the amount of incoming solar radiation throughout the year. They simulate the earth's orbit around the sun using a light bulb and a globe to simulate the seasons. Assessment questions...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Learners investigate how sunlight is used to help plants grow. They use different factors of artificial and natural sunlight in order to simulate the environment of Alaska. Students make observations and then write a report based upon...

Students are introduced to some of the fundamental questions about the connections among population, resources and energy use, and environmental impacts. They explore population growth, interpret a line graph and calculate their own rate...

Students explore various methods for visualizing the results of hydrogen wave function. They observe trends using a polar plot tool and make plots for the first three energy levels of the radial wave function for hydrogen. Students apply...

Second graders investigate the reasons animals hibernate. They measure their own heart rates and compare them to those of a hibernating bear. In their journals, 2nd graders record facts about and characteristics of hibernation and...

In this menu planning worksheet, students use a large circular chart with 5 categories of foods to record one day's diet. There are no examples and the labels "food for growth" and "food for energy" may be confusing.

In this geology worksheet, 10th graders locate 44 terms about natural resources in a word search. Answers are available in various formats.

Seventh graders distinguish characteristics of living things and identify the importance of careful observation. They identify five things that are not alive, but display characteristics of life and list five things that are alive, but...

Students identify various electrical equipment and safety signs and the importance and dangers associated with each. They use cards of power equipment and create a presentation that includes the name of the power equipment that they...

Students read a New York Times article as a class and discuss how groundwater near a nuclear test site may have been contaminated. They explore how groundwater contamination can spread through aquifers by participating in a simulation.

Students examine the concept of organization. In this library skills lesson, students practice ordering and classification skills by playing the Flood Game as well as locating and shelving books in the school library.

Students examine the information given on food labels. They also discover what a serving size is and determine how much they eat over the suggested serving. They also calculate the number of calories are in different foods.

Students determine

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Young scholars illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect...

Students audit their classroom for environmentally friendly practices. In this "green" instructional activity, students take an inventory of the classroom and identify ways to improve practices. Students complete a worksheet, brainstorm...
