Waves and Photons

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

It's quite a write up for a simple demonstration! Connect a nylon cord to an electric drill and generate waves. Explain that wavelength can vary according to the amount of energy added. Questions are included that you can use to guide...

Pairs of physical science pupils play with a beach ball that portrays a particle of light. One partner is the source of photons, and the other is the atmosphere as light strikes it. Three things can happen: the photon (beach ball) is...

Science learners scrutinize shadow size and quality, and experiment with diffraction. They model superposition of electromagnetic waves, and experiment with interference. These activities are action-packed and challenging for your...

A few definitions related to waves open this slide show. Note that the information only covers light waves even though the title mentions sound. Correct the title before using this resource. Another mention is a set of photos of a class...

Electrons, neutrons, and photons display behavior explained by wave-particle duality. The video explains how to picture the duality of behaviors in these parts of atoms. The drawings and comparisons to the behavior of water focus on the...

Help young physicists make a quantum leap in their understanding of matter with this short instructional video. Tracing the early work of Max Planck, Albert Einstein, and others, this resource explains the science behind the amazing fact...

Not sure how to introduce young physicists to the Heisenberg Uncertainty Principal? Well this short video is a great place to start, as it explains how the particle and wave nature of matter makes it impossible to know both the location...

After some online instruction, chemistry aces use their creative abilities to produce a poster describing the photoelectric effect and one type of imaging technology that uses electromagnetic radiation. This simple, straightforward...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...
