SC.6. N.1.2

   The cell theory was developed over a period of 200 years and resulted from combining the work of multiple scientists.  What makes scientific knowledge durable long-lasting?

• A. It will always be expressed under the same conditions.

• B. It is well supported but can change when new evidence arises.

• C. It can be expressed as a statement or as a mathematical equation.

• D. It is something familiar that helps scientists understand anything not familia

SC.7. N.3.1

   Pat was trying to explain to her friends the difference between a theory and a law in science.  She used the theory of plate tectonics and the law of superposition as examples.  Pat explained the difference between by using nonscientific language.  Which statement did Pat use to correctly describe the difference between a theory and a law in science?

• A. A theory describes a natural event, while a law explains it.

• B. A theory explains a natural event, while a law describes it.

• C. A theory explains a natural event, while a law predicts it.

• D. A theory predicts a natural event, while a law explains it.

SC.8. N.1.1

    A school athletic trainer conducted an experiment to investigate the effects of aerobic exercise on high school freshmen.  25 students were examined by a doctor and found them to be healthy.  The trainer had students’ jog, swim, and bicycle.  The trainer recorded the student’s pulse rates before each activity, during each activity, and after each activity.  Which of the following choices is the outcome (dependent) variable?

• A. the student’s health

• B. the aerobic exercise

• C. the number of volunteers

• D. the students’ pulse rates

SC.6. E.7.4

    The Earth contains five spheres that continuously interact.  Which statement is one way the cryosphere and the hydrosphere interact?

• A. When the Sun’s energy melts the ice in the cryosphere, the water flows and joins the hydrosphere

• B. When the Sun’s energy melts the ice in the hydrosphere, they water flows and joins the cryosphere.

• C. Plants and animals from the cryosphere send out water into the hydrosphere through the process of transpiration.

• D. The clouds high up in the cryosphere constantly send water to the hydrosphere through the process of precipitation.

SC.7. 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.8. E.5.5

One evening, Leslie is observing the stars in the constellations Ursa major, also known as the Big Dipper. She wonders if all the stars that make up the constellation have the same surface temperature. The next day, she stops in the school library to find a book on stars to help her answer her question. 

Which of the following characteristics will Leslie use to determine a star’s surface temperature?

• A. size of the star

• B. color of the star

• C. shape of the star

• D. composition of the star.

SC.8. E.5.5

  Gloria is examining a newly discovered star through a powerful telescope.  She wants to find out how bright the star actually is. What information does she need to calculate the absolute magnitude of a star?

• A. color and temperature of the star.

• B. color and composition of the star

• C. apparent magnitude and distance from Earth of the star

• D. color and distance from Earth of the star.

SC.6. P.13.3

  Mrs. Brown asked her student Matthew to help her drag a heavy box to the corner of the classroom. Mrs. Brown pushed the box with 20 N of force while Matthew pulled the box with 15N of force. Newtons represent the amount of force being exerted. What was the net force acting on the box?

• A. 5N

• B. 15N

• C. 20N

• D. 35N

  Gerald prepared a report about heat for his science class.  He learned that heat causes objects to feel hot or cold or to get hot or cold under the right conditions.  Which of the following is an example of how heat energy can be used to influence the rate at which a chemical change occurs?

• A. Increasing the heat in an oven to make a cake bake faster.

• B. Increasing the heat on a stove to make a pot of water boil faster.

• C. Decreasing the temperature in a freezer to make items freeze faster.

• D. Decreasing the temperature in the dryer to increase the drying time.
