Students investigate energy transformations and explore the efficiency of these transformations. First, students will estimate the efficiency of a flashlight bulb to produce energy by using calorimetry to measure how much “waste” heat energy is produced. Then they will calculate and compare price, energy consumption, and cost per hour for incandescent and compact fluorescent bulbs. Includes nine 9V battery harnesses with alligator clips, nine hot bulb trays, nine #50 flashlight bulbs (7.5V, 0.22 amperes), nine sockets, nine foam caps, nine thermometers, one transparency, a teacher’s guide, and 32 student worksheets and guides. Requires eight 9V batteries (not included). For 32 students.
