For this foreign language worksheet, students discover that many Polish words are similar to those in English and the meanings can be guessed. Students read a chart of 220 Polish words and their English translations. Example: balon...

Students, after analyzing the history of a concentrator, model how a Genesis spacecraft concentrator works by playing a game. In groups of three or four, after being given materials to work with, are challenged to roll the rubber balls...

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone...

Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude. (Kevin Costner not included). Java required.

Learn how static electricity results from an imbalance of electrical charges.

In this tutorial, preconceived ideas regarding the nature of charge flow and the role of a battery in a circuit are addressed. In many instances, these preconceived notions about charge flow and batteries are incorrect ideas and are...

In this tutorial the concept of electric potential difference is discussed. Electric potential is the amount of electric potential energy per unit of charge that would be possessed by a charged object if placed within an electric field...

Investigate how to charge objects by induction. Follow up with the suggested interactivity which helps drive home the concept of charging by induction and ends with a game. Test understanding of the concept with provided comprehension...

Students can make a empty soda can roll with an electrically charged balloon.

This review from the Glenbrook South High School provides a series of questions on various topics associated with static electricity (such as electrical insulation). Answers and explanations are hidden, yet easily accessed from within a...

Luigi Galvani was a pioneer in the field of electrophysiology, the branch of science concerned with electrical phenomena in the body. His experiments with dissected frogs and electrical charges led him to suggest the existence of a...

This interactive tutorial begins with an understanding of the structure of matter. Understanding charge as a fundamental quantity demands that we have an understanding of the structure of an atom. Learn the atomic structure of an atom an...

In the wires of electric circuits, an electron is the actual charge carrier. In this article, an electron's path through the external circuit is introduced.

This site is an introduction plus a series of three lesson plans that explore Franklin's portraits plus aspects of his work in science and writing.

Peter Debye carried out pioneering studies of molecular dipole moments, formulated theories of magnetic cooling and of electrolytic dissociation, and developed an X-ray diffraction technique for use with powdered, rather than...

Describes research into the freezing point of water and how scientists have frozen it at different temperatures, depending on the electric charge.

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....

Steer a charged particle to a target, and observe forces and fields.

[Free Registration/Login may be required to access all resource tools.] This lesson looks at what voltage is and how to solve problems involving voltage. Includes a simulation for exploring how charges work in an electric field.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Expand your knowledge of Chemistry. Observe how ionic compounds are networks of electrically charged atoms.

Robert Andrews Millikan was a prominent American physicist who made lasting contributions to both pure science and science education. He is particularly well known for his highly accurate determination of the charge of an electron via...

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage...
