How can people use cows to generate electricity? Students are given a clue before they select their answer to this riddle. In the text and video clip for the clue, two children share information about their unsuccessful attempt to use a pet cow to spin the metal coil in a generator. The riddle's final page presents students with three answer choices. Brief feedback is given for the incorrect choices. When students select the correct answer, a short video clip plays of a farmer explaining how his farm generates more power than it needs by making use of the methane gas released from decomposing manure. There's a link to a text-only version of the riddle. Copyright 2005 Eisenhower National Clearinghouse
