Waves and electromagnetic radiation
Introduction to waves (HS-PS4-1)
SWBAT describe the relationship between frequency, wavelength, and speed of waves in different media.
Class work Go to your book to Unit 3: Waves Lesson 1: The nature of Waves SWBAT describe the relationship between frequency, wavelength, and speed of waves in different media. Write in your notebook: Definition of waves Find the different kinds of waves
Class work Waves in Different Media (HS-PS4-1) • Objective: SWBAT use mathematical representations to compare wave behavior in air, water, and solids. • Activities: • Engage: Video demonstration of seismic and sound waves in different media. • Explain: How waves change speed in solids, liquids, and gases (McGraw Hill examples). • Explore: Group activity—students compare data on wave speeds in various media. • Evaluate: Concept check questions from textbook.
How does increasing tension affect wave speed? How does this relate to real-world wave behavior in solids, liquids, and gases? Why does wave speed increase with tension?
Digital vs. Analog Signals (HS-PS4-2) Objective: SWBAT evaluate the advantages and disadvantages of digital and analog transmission.
Activities: Engage: Compare sound quality from a vinyl record vs. a digital file. Explain: Digital vs. analog signals (McGraw Hill book diagrams). Explore: Small-group discussion—classify technologies as digital or analog. Evaluate: Quickwrite—Which type of signal is more reliable and why?
The Dual Nature of Light (Wave-Particle Duality) (HS-PS4-3) Objective: SWBAT evaluate claims and evidence supporting the wave and particle models of light. The Electromagnetic Spectrum and Energy of Waves (HS-PS4-4) Objective: SWBAT describe how different frequencies of EM waves interact with matter. Evaluating Claims About EM Radiation (HS-PS4-4) Objective: SWBAT evaluate the validity of claims about electromagnetic radiation in media sources. Wave-Based Technologies (HS-PS4-5) Objective: SWBAT explain how technologies use waves to transmit and capture information.
