Activity 3 of this module explores: Is the particle model always better? Models are considered most useful when a variety of observations can be explained. A model of matter should explain observations of all types of matter. In this...

Using understandable words and exceptional graphics, this page describes the transfer of energy by means of conduction. Contains several links to related topics.

This website describes trophic levels, transfer of energy between trophic levels, pyramids of ecology, and nutrient cycles within the environment.

In this animation you will see how dermestid beetles feed on a dead mouse's body for four days, releasing the nutrients trapped in its flesh. Links to a sparrow animation as well.

This lesson explains how energy can be transferred from one form to another, but is always conserved. It is 2 of 4 in the series titled "Conservation of Energy."

Explore the cartoons of Rube Goldberg and design a complex machine to perform a simple task. Use scientific design elements and information about energy transfer to build a model of the machine.

Defines work, energy, and power. Explains the work-energy principle, types and forms of energy, and presents some exercises to try.

View a simulation of water flowing under a wheel that causes the wheel to rotate. Energy from the water is transferred to the wheel.

With an overview of topics related to chemical energetics, this site provides a foundation to a study of thermodynamics and information on energy spreading. Topics covered include quantum states, microstates, and energy spreading,...

Students will create their own water turbine to demonstrate the use of water as a renewable energy source. Included is a detailed lesson plan, a video of the activity, and assessment questions.

Defines what work is, presents the formula for calculating the amount of work, explains what conservation of energy means to a scientist, and discusses energy efficiency.

View a simulation of water moving over the top of a water wheel and causing it to move demonstrating the conversion of energy.
