Exploring Energy Efficiency (Developed by SEPUP)

kit #206S

Students investigate energy transformations and explore the efficiency of these transformations. In Part I, students estimate the efficiency of a flashlight bulb to produce light by using calorimetry to measure how much “waste” heat energy is produced. In Part II, students calculate and compare price, energy consumption, and cost per hour for incandescent and compact fluorescent bulbs.
