In this online interactive, learners first explore the great American inventors and their inventions as well as the role of the National Park Service. Then, learners investigate how Edison's work affects our lives today. Learners are presented with a series of household items and must decide if Edison invented the device, perfected it for mass production and use, invented a device on which the modern object is based, or had nothing to do with the device at all. This resource includes background information about Edison's inventions and the legacy of his work. (less)

Students gain a basic understanding of the engineering components behind telecommunications, in particular, the way telephone communication works to link one phone to another for conventional landline and cellular telephones. During this entire-class activity, students simulate how phone calls are connected by acting out a variety of searches for both local and long-distance calls. Students end up with a good understanding of how phone calls are transmitted from callers to recipients. (less)

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada. Learners are challenged with figuring out how to connect the roads to all the drill sites while keeping the total road length to a minimum. They'll discover that intersections or "Steiner" points provide efficiency between points within a network. Use this activity to introduce learners to computer science themes including Steiner trees, algorithms, and NP-complete problems. Variations, extensions, background information, and solutions are included in the PDF. (less)

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution. Groups of learners (at least 10) repeat a secret message (five to seven similar-sounding words) like the game "Telephone". In this version of the game, however, learners write and then code what they hear, creating a model of a phylogenetic tree and using a species distance matrix. This resource includes background information about phylogenetic trees, maximum parsimony, and matrix theory (see page 6-7 of PDF). (less)

This collection looks at inventors and inventions that changed our lives: the telegraph, photophone, animation, sewing machine, ice cream cone, nuclear fission, flight, and others. It includes Thomas Edison's journals and failed inventions, and Alexander Graham Bell's notebook entry describing the first successful experiment with the telephone (March 10, 1876). George Westinghouse, James Smithson, Benjamin Banneker, and Samuel Morse are among others profiled. (less)

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials. Participants explore how increasing and decreasing friction on a string changes the sound of a pitch. They also experience how sound is amplified. Learners can expand the activity by linking their string things to create a "telephone" or making different instruments from other recycled materials. (less)

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel through different mediums, and are enhanced or mitigated in designed sound environments. They are introduced to audio engineers who use their expert scientific knowledge to manipulate sound for music and film production. They see how the invention of the telephone pioneered communications engineering, leading to today's long-range communication industry and its worldwide impact. Students analyze materials for sound properties suitable for acoustic design, learning about the varied environments created by acoustical engineers. Hands-on activities include modeling the placement of microphones to create a specific musical image, modeling and analyzing a string telephone, and applyling what they've learned about sound waves and materials to model a controlled sound room.

In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering. (less)

In this activity, students investigate how sound travels through both string and air. First, they analyze the sound waves with a paper cup attached to a string. Then, they combine the string and cup with a partner to model a string telephone. Finally, they are given a design scenario to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the telephone has had on society. (less)
