This lesson focuses on the following Three Dimensional Learning aspects of NGSS: 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.Р”В¬lick to view other curriculum aligned to this Performance Expectation Summarize the major properties and behavior of waves, including (but not limited to) wavelength, frequency, amplitude, speed, refraction, reflection and diffraction.Distinguish between mechanical and electromagnetic waves.Explain that waves transfer energy, not matter.Through this legacy cycle lesson, students begin to gather the knowledge necessary to come up with a solution to the engineering challenge outlined in lesson 1 of this unit.Р”Р„fter this lesson, students should be able to: Before designing a solution to a challenge, engineers conduct research and gather information as a crucial part of the engineering design process.

Engineers also use their understanding of wave properties when designing electronics-to separate different types of waves so that radios tune in to the right stations, or so your cell phone only picks up the calls that you want. To predict how tsunamis will travel after a ocean earthquake, engineers must understand wave properties and how they travel. Engineers must understand all the properties of waves and how waves can differ from one another in order to design safe and effective products. For example: microwave ovens, x-ray machines, eyeglasses, tsunami prediction, radios and speakers. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Р”В®ngineers apply their knowledge of waves to design an array of useful products and tools, many of which are evident in our everyday lives. With this knowledge, students better understand waves and are a step closer to understanding how humans see color. They also make observations about the waves they drew to determine which has the highest and the lowest frequency. Then they label wave parts on a worksheet diagram and draw their own waves with specified properties (crest, trough and wavelength). During the presentation of lecture information on wave characteristics and properties, students take notes using a handout. Students learn about the types of waves and how they change direction, as well as basic wave properties such as wavelength, frequency, amplitude and speed.
