Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature.

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how...

Students form expert engineering teams working for the (fictional) alternative energy consulting firm, Greenewables, Inc. Each team specializes in a form of renewable energy used to generate electrical power: passive solar, solar...

A large part of engineering involves presenting products, concepts, and proposals to others in order to gain approval, funding, contracts, etc. The purpose of this activity is to fine-tune students' presentation skills while allowing...

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. This page describes activities in which the interconversion of chemical and electrical energy are investigated. Complete activity...
