Ohio Grade 8 Achievement Test for Science – May 2007 Annotated Item 11 Standard and Benchmark Assessed: Standard: Benchmark: Earth and Space Sciences C. Describe interactions of matter and energy throughout the lithosphere, hydrosphere and atmosphere (e.g., water cycle, weather and pollution). Extended Response Question: Use the information in the table and maps below to answer questions 7-11 Weather Table and Maps The weather information shown below was reported on Sunday, the 15th of the month, and two days later on Tuesday, the 17th of the month. The table includes conditions for Sunday only, whereas the maps report early morning conditions for both Sunday and Tuesday.

In your Answer Document, using the two weather maps and the table of weather data, predict the likelihood of precipitation and probable sky conditions (cloud cover) at Cleveland, Ohio, for Sunday and for the following Tuesday. Give reasons for your predictions for each day. (4 points) Commentary: This extended response question asks students to predict the likelihood of precipitation and probable sky conditions (cloud cover) in Cleveland, Ohio on two given days based upon provided weather maps and weather data. Students must read and interpret the weather maps and table of weather data and communicate their understanding of weather patterns typically associated with low and high pressure weather systems and with the movement of cold and warm fronts. Students must interpret the given weather information in the context of their understanding of weather concepts and make a scientifically valid prediction regarding likely weather conditions for each specified day. Students must also support their predictions with evidence from the weather maps and weather data. Students must communicate a correct prediction for Sunday and Tuesday. The response that earns full credit correctly predicts precipitation and cloudy skies for Sunday because of a cold front that is passing through Cleveland and clear skies with no precipitation for Tuesday because there is no frontal system nearby. This question is classified as Communicating Understanding / Analyzing Science Information because the task requires students to recall information regarding weather concepts, interpret and analyze weather maps and data tables and make an accurate prediction regarding weather patterns.

There is a high likelihood of rain and the sky will be cloudy when the front passes through. On Tuesday the weather should be sunny (no clouds or precipitation) because of the nearby high pressure air mass. Other Correct Response(s): On Sunday it should be windy and rainy with dark clouds and then turn clear and colder Source: Ohio Department of Education August 07 Ohio Grade 8 Achievement Test for Science – May 2007 Annotated Item 11 as the cold front passes through. On Tuesday the sky should be clear with no rain because there are no frontal systems nearby. Scoring Guidelines: Points 4 point 3 point 2 point 1 point 0 point Keywords: Student Response The response provides correct weather predictions (including sky conditions and likelihood of precipitation) for both Sunday and Tuesday and a correct, supporting reason for each prediction. The response provides correct predictions for both Sunday and Tuesday, but the supporting reason for one of the days is incorrect, unclear, or missing. 3 point sample answer: The weather on Sunday should be cloudy and rainy because of the cold front nearby and on Tuesday it should be clear because the rain moved away. The response provides one correct prediction with a supporting reason, but an incorrect prediction on the other day OR the response provides correct predictions for both days but has incorrect, unclear, or missing supporting reasons for both days. 2 point sample answer: The weather should be clear on Sunday because of the cold front nearby. The weather should be sunny with no rain on Tuesday because of the high pressure system nearby. The response provides the correct prediction for one day but has an incorrect, unclear, or missing supporting reason for that day. 1 point sample answer: The weather should be sunny on Tuesday because it is a couple of days after Sunday. The response fails to provide a correct prediction for either day. The response does not meet the criteria required to earn one point. The response indicates inadequate or no understanding of the task and/or the idea or concept needed to answer the item. It may only repeat information given in the test item. The response may provide an incorrect solution/response and the provided supportive information may be totally irrelevant to the item, or possibly, no other information is shown. The response may name the days of the week without supporting information. The student may have written on a different topic or written, “I don't know”. 0 point sample answer: There is a likelihood of precipitation and sky conditions on Sunday and Tuesday. weather Source: Ohio Department of Education August 07
