## Professional Development Opportunity Detail Page

Name: light Modeling Workshop at ASU
School/Institution: Arizona State University
Department/Unit: Physics
City: Tempe
State: AZ
Opportunity Type: Modeling Workshop
Teacher Status: Preservice
Inservice
Teacher Level: High School
Description: Open to teachers nationwide.

Location: Bateman Physical Sciences Center, Room H-366
8am to 3:30pm MTWTh, 8am to noon F
course title: PHS 594:

After a day of reviewing their classroom experiences using Modeling Instruction, teachers work through activities, discussions and worksheets, alternating between student and teacher modes, much as they did in the 1st Modeling Workshop in Mechanics. Throughout the course, teachers are asked to reflect on their practice and how they might apply the techniques they learn in the course to their own classes.

Course content: three models of light: Unit 1 starts by modeling light as stream of tiny particles (rays), treating a variety of light behaviors including aspects of geometric optics. The second unit is introduced with experiments that reveal the inadequacy of light as a particle and explains light behavior as a wave.  Finally the wave model of light is discounted and a model of light as a photon is developed.  The units end with a brief introduction of how light can be used to explain the structure of the atom.
Unit 1: Particle Model of Light. In this unit we develop the model of light as stream of particles to explain a variety of light behaviors including shadows, intensity, reflection and refraction.  A variety of experiences in light are pursued including simple low cost activities, high-tech activities and computer simulations.
Unit 2: Wave Model of Light.   This unit starts with activities involving diffraction and interference. The unit activities and labs effectively transition the student from a model of light as a particle to a model of light as a wave.  A section on mechanical waves (one and two dimensional waves) is provided to support student practical comprehension of waves.
Unit 3: Photon Model of Light.  This unit uses the photoelectric effect to support both the model of light as a wave and light as a particle.  The interaction of light with matter is emphasized.   The photoelectric effect is examined to establish the model of light as a photon.  The photon model is then used to explain spectra of light emitted by gasses.  Teachers use both interactive computer simulations and specialized equipment in this unit.
