Standards
Content Standard
Students know that waves have energy.
Process Standard
Students know that models are often used to think about things that cannot be observed or investigated directly.
Vocabulary
amplitude: the distance from a wave's resting position to its crest, or from a wave's resting position to its trough
frequency: the number of wavelengths that pass a certain point in a unit of time
transverse wave: a wave that moves back and forth perpendicular to the direction in which the wave travels
wavelength: the measure of the distance from a point on one wave to the same point on the next wave
?Essential Question What are transverse waves?
Lesson 1
All About Waves
Overview
Engage
In this section, students think about how objects are alike. They learn that five seemingly unrelated objects all transmit energy through waves.
Explore
In this section, students build transverse waves with string, each with different wavelengths, frequencies, and amplitudes.
Explain
In this section, students learn about transverse and longitudinal waves and the characteristics of waves: amplitude, frequency, and wavelength.
Elaborate
In this section, students learn that radio waves are not the same as sound waves. They investigate how people use radio waves for cell phones, televisions, radios, and other uses.
Evaluate
In this section, students examine the Essential Question of the lesson and reflect on their learning. Students also take the All About Waves Assessment.

Lesson 1
All About Waves
Background Information for the Teacher
Energy waves are a significant part of the world around us. Waves allow us to see, hear, and enjoy many technological luxuries. While this may seem complex, a wave is simply a disturbance that transfers energy from one place to another.
There are two types of energy waves, mechanical waves and electromagnetic waves. All mechanical waves require a medium to travel through. This matter can be in any state, whether it be solid, liquid, or gas. Electromagnetic waves do not require a medium to travel through, although they may travel through a medium as well. These waves can propagate through space or through a vacuum.
Waves may be present in either of two forms: transverse waves or longitudinal (compression) waves. Transverse waves transfer energy perpendicular to the direction in which they travel. These waves are what most people understand to be waves. In the image below, a child is moving a hose up and down, creating a wave with the water stream. The energy of the wave comes from the up and down motion of the child's hand. The wave in turn is moving in the opposite direction or perpendicular to the up and down motion.
Longitudinal waves move energy parallel to the direction in which they travel. The best way to picture this type of wave in action is with a spring toy. In the image below, the energy from the wave is moving from left to right, likewise, the wave (seen in the compression and rarefaction) is moving parallel to this motion.

direction of wave and energy
All waves have amplitude, wavelength, and frequency. These characteristics are easier to see (and learn) through transverse waves. Amplitude is the height of the wave from its resting point. Amplitude is measured either from the resting point to the top of the wave, called the crest, or from the resting point to the bottom of the wave, called the trough. The greater a wave's amplitude, the more energy it carries. All waves also have wavelength. This is the measure of a wave from one point to the same point along the wave, such as crest to crest or trough to trough. The number of wavelengths that pass a certain point within one second is the wave's frequency. Frequency is measured in hertz (Hz). This wave completes three full wavelengths in one second.
