An explanation of how photoelectron spectroscopy can be used to detect electron structures in atoms or molecules.

Students observe, describe, and draw a model on the molecular level, showing how energy is transferred from one substance to another through conduction.

The Thinking Fountain provides this simple experiment for understanding friction and it relationship to energy.

A tutorial that explores the concepts of heat and temperature, the transfer of energy between substances, the relationship of temperature and the movement of atom, and thermal radiation. The tutorial includes animations, interactive...

This simulation shows conduction of thermal energy within and between solids, based on the kinetic energy of particles, and collisions between neighboring particles.

Students learn how water is used to generate electricity. They investigate water's potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements,...

Build the roller coaster, then keep making adjustments to see how it affects the potential and kinetic energy of the marble along its tracks.

Students learn how engineers design devices that use water to generate electricity by building model water turbines and measuring the resulting current produced in a motor. Students work through the engineering design process to build...

An engineering challenge where students create small-scale models from which their testing results could be generalized to large-scale latex tubing for a hydraulic accumulator. They brainstorm ideas about how latex can be used in a...

Read about an innovative technology in fabric that allows users to generate enough electricity through movement to charge devices such as cell phones. Includes video.

This module is the introduction to model rotational motion. All of the concepts are conveniently recast into forms that have the same mathematical forms as their translational counterparts.

A instructional activity for students to explore the conversion of energy from electrical energy to kinetic energy by constructing a homopolar motor. Also by constructing the motor, students can investigate magnetism, electricity, and RPM.

Let this classic family of monsters guide you as you learn about energy. Interactive exercises, experiments, and demonstrations help to build knowledge and raise questions.

During this project, students will be asked to design a device that will measure out a time period of exactly 3 minutes. They will be asked to brainstorm ideas using the different materials provided. Students will observe and explain the...

This site from the University Corporation of Atmospheric Research provides a lengthy page covering numerous topics including the difference between heat and temperature, the use of different temperature scales, thermal expansion, how a...

Through illustrated examples and interactive examples, students learn about the two categories of forces are referred to as internal forces and external forces.

Students learn about friction and drag - two different forces that convert energy of motion to heat. Both forces can act on a moving object and decrease its velocity. Students learn examples of friction and drag, and suggest ways to...

Students must predict the distance traveled by a person on a BMX bike. The person will start with potential energy due to gravity and then convert it into KE. They will then hit a ramp and become a projectile. You have to predict how far...

This tutorial investigates pendulum motion and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the interactive...
