Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

Students calculate the resistance across a bank of resistors in a series, parallel and combined circuit. Using new vocabulary words, they define and describe them in a scientific manner. After stating Ohm's Law, they solve electrical...

[Free Registration/Login may be required to access all resource tools.] Transfer of electric charge: transfer of electrons, conservation of charge and three ways electric charge can be transferred.

This unit teaches students the foundations of electrical circuits and introduces them to their simplest components. Covers series and parallel circuits, Kirchhoff's Rules, Ohm's Law, RC circuits, resistivity, and capacitance.

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...

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,...

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...

Information about what solids are and properties associated with solid matter.

[Free Registration/Login may be required to access all resource tools.] Describes the metallic bond and properties of metals. Includes review questions.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will learn to explain how an ionic bond is formed when electrons are transferred from one atom to another in terms of the...

Learning about charge and forces of attraction will be keys to understanding electrostatics and the basis of this learning unit. Developing a greater understanding of charge and the charge model is necessary to understanding electricity.

Given scenarios or diagrams, students will describe the nature of metallic bonding and explain properties such as thermal and electrical conductivity, malleability, and ductility of metals.

[Free Registration/Login may be required to access all resource tools.] Valence electrons, their variation in the periodic table and relation to reactivity and electrical conductivity of elements.

French physician Guillaume Benjamin Amand Duchenne invented a device that electrically stimulates muscles. The apparatus gave him new insight into neuromuscular disorders, earned him the epitaph of "father of electrotherapeutics," and...

Visit Vlad and learn about the properties of conductors and insulators, and what materials are used for them.

An electron traveling through the wires and loads of the external circuit encounters resistance. In this tutorial, the concept of resistance is introduced. For an electron, the journey from terminal to terminal is not a direct route....

[Free Registration/Login may be required to access all resource tools.] The factors that affect resistivity are explained, e.g., wire gauge and length, and conductivity. Also touches upon semiconductors and superconductors. The use of...

Students learn the structure and function of the cardiac muscle and study the components of the conducting system that distributes electrical impulses through the heart during the cardiac cycle.

Through 10 lessons and more than 20 hands-on activities, students are introduced to the concept of an environment and the many interactions within it. As they learn about natural and human-made environments, as well as renewable and...
