Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.

Students build and use a reflective solar cooker to cook marshmallows.

Middle schoolers discuss reasons and methods for keeping a home warm in winter and cool in summer as examples of energy storage. Students participate in a solar energy experiment.

Students measure and record the mass of the nut to be tested to the nearest 0.01 gram.

Students design an energy resource wheel and demonstrate how to use it to access information about renewable and nonrenewable energy sources.

Explains different kinds of energy, covering kinetic, potential, gravitational, mechanical, sound, thermal, chemical, electrical, and radiant energy. Also looks at storage, transfer, and dissipation of energy. Includes a short...

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back. What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing.

What factors are important to consider in order to make informed energy decisions? In this interactive, you select one of three locations and the energy resources and then try to provide 100% of that community's electricity needs while...

Find out what the human body needs to function at its best, and why.

[Free Registration/Login Required] Create a science test that checks for student understanding in science, for common misconceptions, as well as for correct ideas. This is a list of key ideas related to Energy: Forms, Transformation,...

Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

Students learn how engineers harness the energy of the wind to produce power by following the engineering design process as they prototype two types of wind turbines and test to see which works best. Students also learn how engineers...

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

Use this resource to learn about how the Department of Energy provides information on science competitions, energy conservation, case studies and more.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students are asked to demonstrate and apply the law of conservation of momentum.

At one time, humans, fueled by the animals and plants they ate and the wood they burned, or aided by their domesticated animals, provided most of the energy in use. All life operated within the fairly immediate flow of energy from the...

A food web is a way of seeing how energy is transferred from organism to organism. All living things need energy. They use it to move, to grow, to reproduce. That energy has to come from someplace. Drawing a food web is a great way to...

In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

An indexing page for the HyperPhysics site. The page contains a concept map of links to a variety of other pages which discuss concepts related to heat engines. All pages contain informative graphics and excellent explanations.

The motion of three simple harmonic oscillators is animated to illustrate the effects of mass and spring constant upon the motion. Several equations and a lengthy discussion accompany the animations.

Describes the definition and relationships between force, work and power. Includes nice drawings to increase conceptual understanding.

Students will explore ways that people can conserve energy. Beginning with a classroom survey, students research, consider changes that can be made, and evaluate which changes will be easier to do than others and explain why.
