Product Description

By: The Flinn Staff

Is a stereo speaker just another “black box” to your students? Let students discover for themselves how a speaker works using only two plastic cups, a coil of wire, magnets, and speaker wire to construct a real working speaker. Students will be amazed when they plug their handmade speaker into a radio and actually hear a tuned-in station! Experimenting with different variables will allow students to improve the quality and sound of the speaker. Throughout the process, students learn fundamental concepts such as the conservation of energy, as electricity is converted to sound, electromagnetism, resonance, amplitude and frequency. An excellent real-world experiment that your students are sure to remember whenever they see a radio speaker! Enough reusable materials for 8 student groups, one battery-operated AM/FM radio, detailed instructions, and Teacher Notes are provided. Two AAA batteries are required and available separately.

Batteries, AAA, Alkaline, 1.5 V
The AAA, AA, C, D, and 9 V batteries shown are all alkaline batteries. Consumer Reports states that while alkaline batteries cost three to five times more than acidic batteries, alkalines last 10 times longer.
