Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

Students discover that pure water does not conduct electricity and that dissolving different substances in water may or may not cause it to conduct electricity.

Uncountable times every day "with the merest flick of a finger"each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the...

Straightforward introduction to electrical circuits using minimal materials and time. Students learn about the basics of electrical circuits by experimenting with "mystery cards" -- index cards with hidden aluminum foil used to conduct...

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Java required.

Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution...

Explore charge interactions, the charging of objects by conduction and induction, and the grounding of objects in this interactive.

In this activity, students will understand that electricity moves through different circuits and discover what types of materials are conductors and insulators.

University of Delaware Physics Department provides this indexing page for a slide show presentation.

The University of Delaware Physics Department provides this site from a site titled "Silicon, Circuits, and the Digital Revolution," here is a series of four pages which explain the details behind how semiconductors work. An introduction...

A very detailed look at the element Gallium, a member of the Boron Group.

A very detailed look at the element Indium, a member of the Boron Group.

A very detailed look at the element Thallium, a member of the Boron Group.

A review of electrical conductors and insulators, with diagrams, activities, and quiz questions.

Students learn about static electricity using terms such as friction, induction, and conduction. They also explain and illustrate the difference between alternating and direct current, and understand the relationship among voltage,...

This is the encyclopedic entry for electrical conductivity from Wikipedia.com. The site provides a brief introduction to the topic but provides numerous links to information relative to the topic.

Describes the properties of seawater and the variations depending on its location, e.g., near a shoreline, in an estuary, or as sea ice. Discusses the instruments scientists use to measure the density of water and explains other...

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

Through nine lessons, students are introduced to a range of energy types--electrical, light, sound and thermal-as well as the renewable energy sources of wind, hydro (water) and solar power. Subjects range from understanding that the...

Students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations. They become familiar with where the most...

A lengthy page from the Fundamentals of Physical Geography site. Energy is distinguished from matter, and the different forms of energy are identified and discussed. Four types of heat transfer (convection, advection, conduction,...

Simulate the movement of a rail gun in this interactive model. Learn how a magnetic field is generated by running electrical current through long rods that accelerates a current-carrying cross-rod.

Students in this activity will build simple circuits using a battery, wires, and light bulbs. This activity allows students to examine how electricity is conducted through a light bulb using a battery as a power source. Students will...
