RATIONALE

In today’s classrooms, educational ped-agogy is often founded on Benjamin S.Bloom’s “Six Levels of CognitiveComplexity.” The practical applicationof Bloom’s Taxonomy is to evaluate stu-dents’ thinking skills on these levels,from the simple to the complex:Knowledge (rote memory skills),Comprehension (the ability to relate orretell), Application (the ability to applyknowledge outside its origin), Analysis(relating and differentiating parts of awhole), Synthesis (relating parts to awhole), and Evaluation (making a judg-ment or formulating an opinion).

The AIMS Teaching Module is designedto facilitate these intellectual capabili-ties, AND to integrate classroom expe-riences and assimilation of learningwith the students’ life experiences, real-ities, and expectations. AIMS’ learnerverification studies prove that our AIMSTeaching Modules help students toabsorb, retain, and to demonstrate abil-ity to use new knowledge in their world.Our educational materials are writtenand designed for today’s classroom,which incorporates a wide range ofintellectual, cultural, physical, and emo-tional diversities.

OBJECTIVES

Waves: Energy in MotionTHEMES

Waves: Energy in Motion exploresthe characteristics of different waves,including transverse, longitudinaland standing waves. Behavioralaspects of waves are also discussed,such as reflection, refraction, diffrac-tion and interference. Sound intensityand the mechanisms of human hear-ing are also explored.

OVERVIEW

Waves carry energy, but not matter,from one place to another. The lowpoint of a wave is called the trough,while the high point is known as thecrest. The difference in heightbetween the crest and the trough of awave is called amplitude. The dis-tance between the crests is referred toas wavelength. In a transverse wave,the particles of the medium moveperpendicular to the direction of theenergy flow. In a longitudinal wave,particles of the medium move backand forth. Sound waves are mea-sured by the frequency of the vibra-tion that produces them. Thisfrequency is measured in hertz.

To learn more about the charac-teristics of different waves,including transverse and longitu-dinal waves.

To discuss wave behavior pat-terns such as reflection, refrac-tion, diffraction and interference.

To examine the how sounds areproduced by musical instruments.

To explore the human ear and itsability to perceive sound.

To discuss how sound intensity,amplitude and frequency aremeasured.

INTRODUCTION TOTHE PROGRAMSound is produced when a movingobject vibrates. The vibrations movethrough the air and are picked up byanimals and humans, whose brainsinterpret the vibrations as variousnoises.

Light is a form of energy that pro-duces heat and allows us to see. Lightkeeps us warm. It is also helps plantsmake food through the process ofphotosynthesis. This is the basis of alllife on Earth. Without light, nothing inthe world could survive.

INTRODUCTION TOVOCABULARYAsk students to look up the word“wave” in the dictionary. What aresome of its meanings? What is theorigin of the word “wave”? (Theword “wave” has many meanings,both as a noun and a verb. As averb, it means to shake an air current;motion with the hands; or move anobject to and fro. As a noun, it refersto a moving ridge or swell; a shapewith a curve; a surge of feeling; a lineof attack during war; or a period ofhot or cold weather. The word origi-nates from the Middle English wordwaveren which comes from the OldEnglish word waefre, meaning rest-less.

DISCUSSION IDEAS

Ask students to think about thedifferent types of waves that aresurrounding them at any givenmoment. What are some ways toprove that these waves exist, eventhough we cannot see them?(Shadows prove that light waves canbe blocked. Echoes prove that soundwaves can bounce off of objects.Plucking the string of a musicalinstrument proves that vibrationscreate waves that can be heard.)

FOCUS

Ask the class to think about how lightand sound affect their world. Whatwould life be like without thesethings? How must people with visionand hearing impairments adapt?How often do we consider the bene-fits of sight and sound?

SUGGESTED ACTIVITIES

Writing

During the 1800s, scientists began to understand how to record and transmit sound waves.Some of the most important contributors to our understanding of sound are listed below. Askstudents to choose one of the people and investigate the work that person did with soundwaves. Have each student prepare a one-page report on the person using library texts andencyclopedias.

Alexander Graham BellEmile BerlinerThomas A. EdisonHermann HelmholtzErnst MachHeinrich Hertz

Meeting Individual Needs

Ask students to make sentences using the following words. Encourage them to use a dictionaryif they are confused about the meanings. Make sure that their sentences display an under-standing of the words as they relate to the program.

• amplitude - the strength of a sound wave • pitch - the highness or lowness of a sound wave, based on frequency or wavelength• wavelength - the distance between the crests of two waves • frequency - the rate of vibration of a sound wave

Connection to Nature Studies

Many animals, such as owls and cats, hunt at night instead of during the day. Some peoplebelieve that these animals can see in the dark. Is this possible? (No. A small bit of light mustbe present for all creatures to see. Without light, the eye cannot process images.)

Some animals, such as dogs and rabbits, cannot see colors like we do. They see things only inblack or white. However, animals that are brightly colored, like butterflies and birds, almostalways see in color. What could be the reason? (Some animals are brightly colored so theycan recognize each other and attract mates. Being able to see colors is important for their sur-vival.)

Critical Thinking

Ask students if they have ever placed a seashell against their ears to hear the “ocean.” Whatcould be the explanation for this phenomenon? Why do we hear sounds better when we cupa hand behind our ears? (The inside of a seashell is like a cone. The wide opening collectssounds and directs them inside the shell. As the shell narrows, the sound waves bounce aroundand become louder. This makes ordinary room noises, which we usually don’t notice, seemlouder. When we cup a hand around our ear, our hand collects more sound waves and directsthem into our ear. More sound waves hitting our eardrum makes a sound seem louder.)

Hands On

In times past, warriors placed their ears near the ground to hear approaching enemy horses.To find out how this works, assist students in doing the following experiment. They will need apencil, an aquarium or other large glass container filled with water, and a wooden or metaltable.

Allow students to take turns performing the following steps. 1) Strike the pencil against themetal table. Listen carefully to the sound. 2) Submerge the pencil in the container of water andstrike it against the side of the container. With an ear against the container, listen for changesin the sound. 3) Pressing an ear to the table, strike the pencil against the table top.

Which of the sounds was loudest? Which was softest? What could be the reason for thechanges? (The sound is louder when heard through the table [a solid] and softest when heardthrough the air [a gas]. The sound of the pencil in water [a liquid] is somewhere in between.The denser a material is, the quicker sound waves travel through it. This is because dense mat-ter is more elastic and can carry sound waves more efficiently.)

Connection to History

Since ancient times, humans have used the sun to tell time. As a class exercise, help studentsconstruct a sundial. Take the class to a quiet location outside. Place a stick or ruler in theground. It might help to tape a small note to the ruler asking others not to disturb it. Assigneach hour of the school day to a pair of students. Have them mark the end of the ruler’s shadowat the beginning of each hour. After each hour of the school day has been recorded, ask stu-dents the following questions.

At what hour of the day was the longest shadow seen? At what hour of the day was the short-est shadow seen? The ancient Egyptians had sundials so precise, each minute of the day wasrecorded. How could the class sundial be modified for better accuracy? (The longest shadowsof the day will be seen early in the morning and late in the day. The shortest shadow will beseen at midday. When the sun is directly overhead, there will be no shadow. The sundial canbe improved for accuracy by making the dial very thin and tall. The circle used to record min-utes and hours would correspondingly be much larger.)

Extended Activity

Using the spectrum of seven basic colors, scientists have devised the color wheel. Each coloron the color wheel has an opposite color.

Draw a red square on a white sheet of paper. Look at the square while counting to 60, thenlook away from the square at a blank piece of paper. What do you see? (Students should seea green-blue square.)

Red and green are opposites on the color wheel. When you stare at a red square, cells in youreyes that respond to red get tired. When you look away from the red square, these cells takea short break. During this break, you see green. Green is the opposite of red on the colorwheel.

Link to the World

Even though we cannot hear ultrasound waves, they have many uses in the modern world. Justas a laser is a focused beam of light, an ultrasound or ultrasonic wave is a very focused formof sound. Ask students if they know some uses for ultrasound waves. (Ultrasound waves areused by submarines and ships to detect obstacles. The ultrasound waves bounce off of objectsand tell navigators how close the objects are. Ultrasound waves are also used to detect cracksand flaws in airplanes, train tracks and manufactured products. Dentists and doctors use ultra-sonic instruments, such as drills and scalpels, to perform medical procedures. Ultrasoundwaves also allow us to see inside the body. In addition, ultrasound waves are used to killinsects, disinfect surgical instruments and make foods safer to eat.)

Culminating Activity

Ask students to write down an example of each of the following types of waves. Encouragethem to use examples from their daily lives.

• compression wave• sound wave • standing wave• refracted wave• seismic waves• electromagnetic wave• transverse wave• ultrasound wave• longitudinal wave
