SCIENTIFIC CONCEPTS/PROCESSES

  • Energy is transferred in many ways
  • Electrical circuits provide a means of transferring electrical energy
  • Identifying and controlling variables is essential to good experimental design

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.

BATTERY NOTE: This kit requires the use of eight 9-volt batteries that are not included.
