Product Details

Ready, Set, Glow! Clarify the difference between the intensity—or brightness—of light and the energy of light. In this teacher-developed kit, light is shined through a rainbow of filters onto a piece of phosphorescent material. The filters absorb some wavelengths of the light and transmit others. If the transmitted wavelengths of light are high enough in energy, the phosphorescent material will phosphoresce or glow in the dark! This demonstration allows students to explore the reasons for this brilliant phenomenon. A great kit to use when teaching absorption and emission of light, interpretation of transmittance graphs and the photoelectric effect. Detailed Teacher Demonstration Notes included.

Concepts: Phosphorescence, transmittance, absorption, emission.
Time Required: 15 minutes
Materials Provided: Energy in Photons Demonstrator Card.

Performance Expectations

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
HS-PS4-3. Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
