Video Learning Notes
Electromagnetic radiation exhibits both wave-like and particle-like properties. The wave model explains phenomena such as interference and diffraction, while the particle model explains phenomena like the photoelectric effect. Scientific models are tools that help us understand complex phenomena, and sometimes more than one model is needed. Evaluating claims with evidence and reasoning helps us choose the most useful model for a given situation and deepens our understanding of the natural world.
Learning Goals
- Explain how electromagnetic radiation can be modeled as waves or particles (photons).
- Evaluate scientific claims about electromagnetic radiation using evidence and reasoning.
- Identify situations where the wave model or particle model better explains electromagnetic phenomena.
- Use models and evidence to support or revise explanations about electromagnetic radiation.
- Communicate scientific reasoning clearly in discussions and writing.
