Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power...

Students will explore the basics of dc circuits analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's Law and the equation for power dissipated by a circuit will be the primary equations used. Using...

[Free Registration/Login Required] In this interactive activity, change the amount of electrolytes and observe the effect it has on the electrical current to simulate the body's similar function. After the activity, answer one...

Simulate the creation of an induced magnetic field through the use of a simple electric circuit. An interactive demonstration is included.

In this activity, students use the same method as in the activity from lesson 2 to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced...

This Nobel E-Museum website commemorates the work of Philipp von Lenard and his Nobel prize achievement. This detailed resource includes a biography, Lenard's Nobel Lecture, and the "The Nobel Prize in Physics 1905 Presentation Speech."

In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with...

Discusses the scientific principles (the Peltier effect) and the reliability and operation of thermoelectric modules. Includes a link to several other pages, one of which contains an animation of their operation.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

This hour long program by NOVA is split into six segments and examines a issues influencing scientists' current understanding of how the universe was formed. This includes The Big Bang and its lasting effects.
