In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

Prepare young scientists for the ins and outs of lab safety with a thorough list of symbols, icons, and rules about staying safe during experiments. Additionally, the resource provides several assessment pages for kids to reflect on what...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

How much energy does it take to light a room? Class members calculate the total wattage it takes to light the classroom. Through calculations, responsible scientists determine the cost of energy for the year, then figure out...

Joseph John Thomson, better known as J. J. Thomson, was a British physicist who first theorized and offered experimental evidence that the atom was a divisible entity rather than the basic unit of matter, as was widely believed at the...

The nature of insulators is described at the atomic level. Band gap theory is used to explain what distinguishes insulators from conductors.

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...

A brief overview of several type of conductors.

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.

A self-educated man with a brilliant mind, Michael Faraday was born in a hardscrabble neighborhood in London. Through the combination of insatiable curiosity and a powerful will to succeed, he transcended his austere beginnings to...
