BCRs were put on the exam review sheets to encourage appropriate student collaboration and review of concepts in preparation for the entire exam (not just the BCRs). Teachers should not address these BCRs during the course of their instruction and review with students other than highlighting their availability to support STUDENT review and to teach, model and encourage collaboration around the concepts. Students should be prepared to answer any of the following BCRs. Teachers will select two from the list below: BCR 1: The Life of a Star http://hubblesite .org/ There are many variations in stars, including brightness, color, temperature, and mass. Hertzprung and Russell suggested that these variations showed that stars go through different stages. Describe the life of a medium mass star, from the beginning to the end of its existence. In your response be sure to Identify each stage of the star’s life in the correct order Briefly describe the important processes in each stage (gravity, fusion, expand, collapse) Be sure to consider the completeness of your response, supporting details, and accurate use of terms. Write your response on the lines provided on the Constructed Response Answer Sheet. Investigations in Earth and Space Science Student Review 3 MCPS 2015 Student Review Investigations in Earth and Space Science Semester A 2015 Examination BCR 2: Temperature Differences Students investigate the rates of heating and cooling of different surfaces. They collect temperature data from the blacktop surface of a parking area next to a lake and the surface water in the lake. Each surface responds differently to energy from the Sun. Their results are shown in the table below. TEMPERATURES OF BLACKTOP AND WATER Time Blacktop Water Time (Hours) Temp (oC) Temp (oC) (Hours) 1 22 22 12 2 23 22 13 3 24 22 14 4 26 23 15 5 28 23 16 6 30 24 17 7 32 24 18 8 33 24 19 9 34 24 20 10 33 24 21 11 32 24 22 Blacktop Temp (oC) 31 29 27 26 25 24 24 23 23 23 23 Water Temp (oC) 24 23 23 23 23 23 23 23 23 23 23 Compare the rates of heating and cooling of the blacktop to the water in a lake.

Whether or not the eclipse is visible from a specific location on Earth depends on many variables, including Earth’s rotation.

Investigations in Earth and Space Science Student Review 5 MCPS 2015 Student Review Investigations in Earth and Space Science Semester A 2015 Examination BCR 4: Universal Gravitation Newton’s Universal Law of Gravitation states that any two objects exert a gravitational force of attraction on each other. Examples of Newton’s law can be found throughout the universe. For example, the Sun’s gravity affects Earth and other celestial bodies. The gravity of these objects also has an effect on Earth. The extent to which gravity of any object affects another object is determined by many factors, for example distance between the object and the mass of the objects. The Milky Way Describe evidence found in our universe that celestial bodies are gravitationally bound. In your response, remember to include: Specific examples of consistent relationships between celestial objects Discuss how all bodies with mass are gravitationally bound Describe the relationship between mass and gravitational force Be sure to consider the completeness of your response, supporting details, and accurate use of terms.

Investigations in Earth and Space Science Student Review 6 MCPS 2015 Student Review Investigations in Earth and Space Science Semester A 2015 Examination BCR 5: Heat Transfer The atmosphere and hydrosphere are both fluids in motion. The hydrosphere is water on, under, and over the surface of Earth. The atmosphere is the layer of gases surrounding Earth. As they move, both hydrosphere and atmosphere transfer heat energy around Earth. How do the hydrosphere and atmosphere affect global temperature patterns? Be sure to: Briefly describe the patterns of heat transfer in the atmosphere. Briefly describe the patterns of heat transfer in the hydrosphere. Explain how the hydrosphere and atmosphere re-distribute heat energy over Earth’s surface. Be sure to consider the completeness of your response, supporting details, and accurate use of terms.
