University of Miami scientists developed a new type of bandage that will keep bacteria out of a wound.  What conclusion can be made from this information?

• Scientific discoveries always lead to new technologies

• Scientist often respond to the needs in our society

• Scientific advances are always made in the field of medicine

• Scientist may make discoveries that have no impact on society

SC.6. N.1.1

Eric wants to make sure he understands the parts of a good scientific investigation.  He knows that scientific investigations include many different steps.  During a scientific investigation, which step occurs after a scientist collects data?

• Draw Conclusions

• Form the hypothesis

• Plan the experiment

• Follow the procedure

SC.8. N.1.1

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

• Observe different skateboarders riding down hills of different heights

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

• Perform an experiment in a lab which the angle of the ramp is controlled and the speed of a rolling cart is measured

• Observe video 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?

• Space station

• Rocket

• Space probe

• Artificial satellite

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?

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

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

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

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

SC.6. E.7.5

The diagram represents the different parts of the water cycle.

What combination of heat transfer allows for letter C in the diagram to occur?

• Evaporation, due to convection and radiation

• Evaporation, due to radiation and conduction

• Condensation, due to convection and radiation

• Condensation, due to radiation and conduction

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?

• Glacial erosion

• Cementation of sediment

• Deposition of sediment

• Weather of rocks

Below is a diagram of the transformation of sediment to magma.

Sediment ----?---> Limestone ----?----> Marble ----?----> Magma

  Which choice accurately demonstrates the geological processes that must occur to transform sediment into magma.

• Compacting and cementing, cooling, melting

• Compacting and cementing, melting, weathering, and erosion

• Weathering and erosion, heat, and pressure, melting

• 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 form of matter changes state from solid to liquid

• A substance forms that releases heat and light

• Carbon dioxide, water, and ash are produced

• There are signs of rusting on a metal object

SC.8. P.9.2

In a physical or chemical reaction, the total amount of the products must be equal to the total amount of the starting materials.  Which of the following laws is defined by this statement?

• The Law of Universal Gravitation

• The Law of Chemical Properties

• The Law of Conservation of Energy

• The Law of Conservation of Mass
