AM I on the Radio?

(Complete Item Description)

Abstract:: During this activity, students create a working radio by soldering circuit components supplied from an AM radio kit. Since this activity is carried out in conjunction with the associated lessons concerning circuits and how an AM radio works, students should be able to identify each circuit component they are soldering, as well as how their placement causes the radio to work. Besides reinforcing concepts from the lessons, this activity will also teach students how to solder. Soldering is an activity that many engineers perform regularly; by teaching students how to solder, they are able to engage in a real engineering activity.

Making a Liquid Xylophone

(Complete Item Description)

Abstract:: Students design musical instruments inspired by what they learn in an experiment with beakers of different liquids. In the "research and investigate" stage of design, they experiment to determine the general relationship between pitch (frequency) and liquid density. They use their results to draw designs for instruments that can create sound at several different pitches.

Riding the Radio Waves

(Complete Item Description)

Abstract:: Through this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the amplitude and frequency of a given waveform. Students then learn general concepts about magnetic fields, leading into how radio waves are created and transmitted. Several demonstrations can be performed in order to help students better understand these concepts. The goal of this lesson is for students to understand how the AM radios built during the associated activity function.

Sound and Light

(Complete Item Description)

Abstract:: The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in Lessons 6-10, they explore the concepts of light. The first lesson introduces the concepts of longitudinal and transverse waves. Students then move on to the concepts of wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, girls and boys learn all about echolocation what it is and how engineers use it to "see" things in the dark, or deep underwater. The last of the five sound lessons introduces acoustics, in which students learn how different materials reflect and absorb sound.
