Introducing LEDs, Thermistors, and Transistors A lesson in five consecutive parts.
Introduction: An Introduction to the units on LEDs, Thermistors and Transistors
Lesson 1: Ohm's Law With Light Bulbs and LEDs The purpose of this activity is to illustrate ohmic and non-ohmic materials in a simple series circuit.
Lesson 2: The Effect of Temperature on the Electrical Resistance Properties of a Thermistor A thermistor is a semiconductor, a group of materials classified as having properties of both conductors and insulators. This experiment illustrates how temperature affects electrical resistance of a semiconductor.
Lesson 3: Thermistor Circuit The purpose of this activity is to show a thermistor’s usefulness within a circuit. This activity will introduce thermistors in a circuit so that future activities may build upon this idea to conclude with micro/nano-circuits.
Lesson 4: LED Circuit Combination The purpose of this activity is to show an LED in a circuit. This activity will introduce diodes in simple circuits so that future activities may build upon this idea to conclude with micro/nano-circuits.
Lesson 5: Transistors as Switches and Amplifiers The purpose of this activity is to become familiar with transistors and their uses as switches and amplifiers.
