### Catch a Wave

By: Catherine Livesay and Diann Musgrove

### For the Teacher

Discovering Waves

Lesson Overview
• Identify parts of the waves
• Calculate frequency, amplitude, and wavelength

In this lesson, students learn about the parts of a wave, and discuss wave height, wavelength, and frequency. They will demonstrate waves using various materials and measure parts of the waves.

Instructional Goals
• Student will identify parts of the wave including crest, trough, height, wavelength, frequency, and amplitude of a wave.
• Students will demonstrate an understanding of the movement energy through a wave.
Formative Assessment
• Assessing prior knowledge through classroom discussion
• Teacher observations during simulation activities
• Accuracy of student calculations of amplitude
• Think-Pair-Share
Opening The Lesson
• Play music “Catch a Wave” or other beach related music
• Oral reading of Waves from Surfing to Tsunami by Drew Kampion
• Classroom discussion of the book
• Lead the students in a discussion of the parts of a wave.

Developing The Lesson
• Classroom discussion of the book
• Lead the students into a discussion on the parts of a wave.
• Use ropes and a slinky to demonstrate different wave heights, lengths, and periods. Have a student volunteer to hold one end. By lifting and lowering the other end at different speeds and heights, create different sets of waves for the students to see.
• Ask students to imagine how a boat might react as the waves change sizes and periods.
Draw a simple picture of a wave on the board so all of the students can see it.
• Explain that each part of a wave has a name. Identify the crest, trough, wave height, and wavelength of each wave.
• Then, show the students that a wave period or frequency is measured as the time it takes for two consecutive crests to pass a given point, and that all of these variables affect how a wave may look from a boat.
Ask the students to imagine that they are on a sailboat. Explain to them that a wave with a long wavelength or long wave period might just feel like a gentle roll, or riding a bicycle on a road with really shallow hills, regardless of the height of the wave.
• Next, ask them to think of a really massive roller coaster. As waves decrease in wavelength or increase in wave period, they become steeper. A single 100-foot (30-meter) wave might cause nothing more than a gentle rocking motion out in the open ocean where it has a long wavelength; however, several 18-foot (six-meter) waves could seem enormous if the boat has to rise steeply over each one.
• Have them discuss which has a greater amplitude.
• Teach them how to calculate the amplitude of the wave.
Tell students that they have been transported to a sailboat traveling around the world.
• Place the students in pairs, or small groups and have them try to create waves for a point on each ocean.
Closing The Lesson
• Review the parts of the wave and the concepts of wave height, wavelength and wave period. Ask the students to describe the waves that they created.
