  A group of student researchers want to find out how the angle of a ramp affects the speed of a skateboard rolling down the ramp. There many different ways the investigation can be conducted.  Which investigation should they perform?

• A. Observe different skateboarders riding down hills of different heights.

• B. Record the time it takes one skateboarder to ride down hills of different heights.

• C. Perform an experiment in which the various angles of the ramp are controlled, and the speed of a rolling skateboard is measured.

• D. Observe videos of various objects rolling down hills and estimate the angle of the hill and the speed of the object.

SC.8. E.5.10

Some places in the universe are too distant for humans to observe directly.  The Hubble Space Telescope orbits the Earth and collects data and images from distant parts of the universe.  Which of these technologies would describe the Hubble Space Telescope?

• A. Space station

• B. Rocket

• C. Space probe

SC.6. E.7.4

  Scientists have been studying the rate of melting glaciers around the world for over a century. They are concerned that some of the world’s largest glaciers are melting at ever increasing rates. Which of the following statements best describes how melting polar ice could most likely affect the climate on Earth?

• A.   Worldwide temperature may fall due to the cooling of the oceans by the melting ice.

• B. Worldwide temperatures would fall as land cools off at a faster rate than the oceans.

• C. Worldwide temperatures may rise because the glaciers are no longer reflecting solar radiation.

• D. Worldwide temperatures would be higher in the summer with no ice to cool the atmosphere, but no change in winter temperatures.

SC.6. E.6.2

  A delta is defined as a triangular mass of sediment, silt, and sand, deposited at the mouth of a river. Deltas form when a river flows into a body of standing water, such as a sea or lake, and deposits large quantities of sediment. They are usually crossed by numerous streams and channels and have exposed as well as submerged areas. Which process was primarily responsible for the formation of a delta?

• A. Glacial erosion

• B.   Cementation of sediment

• C. Deposition of sediment

• D. Weather of rocks

SC.7. E.6.2

Analyze the diagram of the transformation of sediment to magma.

Which geological processes must occur to transform sediment into magma at step of the process? 

• A. Compacting and cementing, cooling, melting.

• B. Compacting and cementing, melting, weathering, and erosion.

• C. Weathering and erosion, heat, and pressure, melting.

• D. Compacting and cementing, heat and pressure, melting.

SC.8. P.9.2

Chemical changes are accompanied by signs that show that a chemical reaction has occurred.  By making careful observations about the chemical reaction, a student can see one or more of these signs.  The signs will provide evidence that the event is not a physical change.  Which of the following is NOT likely to be evidence of a chemical change?

• A.   A form of matter changes state from solid to liquid.

• B. A substance forms that releases heat and light.

• C. Carbon dioxide, water, and ash are produced.

• D. There are signs of rusting on a metal object.
