Ohio Grade 5 Achievement Test for Science – May 2007 Annotated Item 33 Standard and Benchmark Assessed: Standard: Benchmark: Physical Sciences E. Trace how electrical energy flows through a simple electrical circuit and describe how the electrical energy can produce thermal energy, light, sound and magnetic forces. Multiple Choice Question: 33. Electric energy flows through the wire filament in a light bulb. The energy flow causes the wire to glow and give off light. Which type of energy produces this light? A. B. C. D. sound gravity thermal magnetic Source: Ohio Department of Education August 07 Ohio Grade 5 Achievement Test for Science – May 2007 Annotated Item 33 Commentary: This multiple choice question asks students to recognize the type of energy that makes a light bulb filament glow and produce light. Students should observe the diagram showing a circuit with a battery and a light bulb. Students must understand that electric energy flows through a circuit and know that it can produce thermal energy, light, sound, or magnetic forces. Students should recognize that the glowing filament of the light bulb indicates that the filament is being heated producing both light energy and thermal energy. Student may also remember that an incandescent light bulb feels hot to the touch when it is producing light. Answer choice C is correct because thermal energy is produced by the light. Answer choice A is incorrect because there is no evidence that sound energy is produced. Answer choice B is incorrect because gravity is not a form of energy. Answer choice D is incorrect because (electro)magnetic energy is generated but is not responsible for producing the light. This question is classified as Recalling/Identifying Accurate Science because the task requires students to know that electric current in a circuit can produce thermal energy, light sound and/or magnetic forces and to identify which form of energy is responsible for producing light from a light bulb. Performance Data: The percent of public school students selecting answer choice C for question 33 on the May 2007 Ohio Grade 5 Achievement Test for Science was 59%.
