Complete a unit of lessons on hearing and sound. Learners conduct sound experiments, research the history of the telephone and scientific contributions of Alexander Graham Bell, and create a model of the human ear.

Students construct a string telephone. In this communications lesson, students use a cup, lead pencil, and a piece of string to construct a string telephone. The students test their telephone with a classmate.

Students study the history of the telephone and its inventor.  In this communications lesson plan students complete a tuning fork experiment to further demonstrate how sound is produced.

Learners investigate sound as a form of energy. In this energy, forces, and sound lesson plan, students work in pairs to examine how sound travels through solid things as they construct a telephone exchange system using string and tin.

Research the life of Alexander Graham Bell in groups, identifying the challenges Alexander Graham Bell faced before he invented the telephone. To end the lesson plan, use construction paper to make models of an old fashioned telephone.

Introduce your class to the concept of creating phylogenetic trees by playing a game of Telephone. Participants create a mixed-up message and through the use of distance matrices, the evolution of the message is recreated. 

Students read about old telephone books are being recycled to make new objects and then answer short answer questions about it. In this recycling lesson plan, students also look into their books to find information.

Pupils read a short biographical account about Bell and student B about Edison. Ask each pair to exchange information and determine what qualities these inventors shared. Ask students if they think all inventors share these qualities.

Learn about communication engineers. Students observe a demonstration using a slinky of how to diminish sound with distance. They also learn about Alexander Graham Bell and his invention of the telephone.

Get to know the body's central nervous system through an engaging game of nervous system telephone. But this isn't your average game of telephone. Here, pupils must find a way to communicate a message to the brain without speaking....

Some interesting diagrams here will pique your students' interest as they discover what is actually inside the telephone that they use every day! The frequency and amplitude labels then lead to further details about sound and waves of...

Sixth graders conduct a controlled investigation to determine the length of the sun's shadow on a fixed object (i.e., flagpole, telephone pole, etc.) over a three-day period (one day in the fall, one in the winter, and one in the...

In this science activity, students complete the exercises that focus on the concept of heat and the use of a thermometer. The sheet also requires prior knowledge of using a telephone.

In this science worksheet, students use basic scientific concepts to complete the series of puzzles that are intended to increase science literacy while focusing upon sound by listening to the tones on a telephone.

Learners explore communication. In this telephone lesson plan, students create a model of what they think telephones of the future will look like. Learners list inventions of the past that have led to current technology. Students then...

Light and sound are the running themes of a read-aloud anthology. Over three weeks, third graders listen to discuss readings in preparation for completing extension activities. Pupils work through the writing process to compose an...

In this nervous system worksheet, students identify 2 ways that a computer and brain, a telephone wire and the spinal cord and a camera and an eye are similar and different.

Students explore the vibrational nature of sound. For this science lesson plan, students gain an understanding of sound frequency, pitch, and conduction using the string telephone, tuning fork and musical glasses experiments.

Fifth graders explore communication by analyzing manners. In this social skills activity, 5th graders review the different forms of communication and how to present yourself in a phone conversation, face to face meeting, e-mail, etc....

Young scholars discover how a fax machine works including: how a light sensor works, how light is reflected and how signals move across telephone lines. A "bingo" type game is played where students simulate the work of a fax machine to...

Sixth graders are able to see the role of chance in evolution. The activity is similar to the party game "gossip" or "telephone." Students start off with a drawing of an animal which changes as they pass their copies of the animal to...

Third graders brainstorm emergency situations. They watch a demonstration of finding emergency numbers in the phone book. They compile a list of specific items they should tell the 911 operator. They demonstrate how to talk to emergency...

A fabulous presentation on light is here for you. In it, learners view slides which cover many important concepts of light. They understand exactly what light is, what the main sources of light are, what opaque, transparent, and...

More of a math instructional activity than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex...
