Morse Code Experiment Kit, 1 Each

The Morse Code Experiment Kit by United Scientific demonstrates the principle of a telegraph with a telegraph key, battery holder, miniature bulb, lamp holder and three alligator clip connecting cords. Students build a simple circuit and send Morse code as light flashes, learning how long-distance communication worked before the telephone. It runs on one D size battery, not included, and comes with an activity guide for elementary and middle school science classes.
