Fifth graders explore electromagnetic waves and light. In this light lesson, 5th graders draw the parts of a wave of the electromagnetic spectrum. They compare a flashlight to a laser to see how the light looks when shined through...
Urbana School District
You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...
Eleventh graders explore the different steps in the engineering process. In this physics lesson, 11th graders design an experiment based on topic given. They prepare a presentation and share it with the class.
Pupils study holographs. In this laser holography lesson plan students make a laser holograph and understand why it works. This can be done as a class.
Typical Numeric Questions for Physics I - Photoelectric Effect
As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...
American Museum of Natural History
Light, Matter and Energy
Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...
STRAINING FOR SOUND
Sixth graders use a laser along with computer microphone probeware and the appropriate software, 6th graders determine the speed of rotating objects.An audio amplifier is connected to a solar cell to change the laser light signal into a...

Fascinating aspects of electromagnetic radiation and its use in obtaining and transferring information are described here. Learners will find the connections to current technology interesting. Although the slides are text-heavy, they do...
Delta, Delta, Delta
Students construct equilateral triangles and a 'laser' triangle. For this reflection lesson students build a retro-reflector using mirrors.
Protecting the Mummified Troll
Students develop an invisible security system to protect a mummified troll. In this security system lesson students view a portion of Mythbusters and begin their challenge.
A Critical Lab
Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...
Laser, and Pagers, and Cells - Oh My!
Students explore the use of various new handheld electronic devices in schools, and assess the appropriate use of each. They present research to school administrators for possible use in the development of new school policies.
