Carolina® Laser Music Demonstration Kit

Item # 754014 Exclusive This product is exclusive to Carolina Biological Supply. With Digital This kit includes 1-year access to digital resources including videos, digital teacher’s manuals, printable student guides, interactive lessons, editable assessment questions, and more.

Grades 9–12. Beam music across the room with a laser in this exciting interactive demonstration. Teach students how information is embedded in waves with modulation to encode an audio signal in a laser beam using a transformer. Students learn about induction and how each circuit component contributes in modulating and demodulating the audio signal with a transformer, laser, battery, and photovoltaic cell.

Grades 9–12. Teach students how information is embedded in waves with modulation to encode an audio signal in a laser beam using a transformer. Students delve into electronic components as they observe electromagnetic induction as a transformer amplifies an audio signal, which is then transmitted across the room via a laser pointer, converted by a photovoltaic cell into electricity, and finally converted back into an audio signal through a dynamic speaker acting as a transducer. The activity effectively illustrates the roles that the components play in encoding and decoding information (modulation/demodulation) and transforming energy from one form to another acting as transducers to play music (e.g., MP3 player, smartphone).
