  5. 12 • A student predicted that black paper will get warmer in sunlight than a piece of white paper. He performed an experiment to test his prediction four times.

A thermometer measures temperature differently on white paper and on black paper. • B. Variables other than the color of paper might have not been constant. • C. Results just differ from trial to trial and do not hve to be the same. • D. The color of the paper does not affect the temperature of the paper. • B. Variables other than the color of paper might have not been constant.

  6. 18 • A good experiment has several characteristics. Which characteristic is part of a good scientific experiment? • A. Results can be reproduced. • B. Results are not reviewed by peers. • C.

  7. 16 • The procedure and data table for an experiment are shown here. • Step 1: Add approximately 25 mL of water to a 50-mL graduated cylinder. • Step 2: Measure and record the initial volume of the water to the nearest 0.1 mL. • Step 3: Carefully slide the object into the graduated cylinder. Measure and record the final volume of the water to the nearest 0.1 mL. • Step 4: Determine the volume of the object by subtracting the measurements in steps 2 and 3. After making several of these measurements, the students analyzed the data. What pattern in the data could be used to predict the final volume if the initial volume is known? • A. The final volume is the sum of the initial volume and the volume of the object. • B. The initial volume is the sum of the final volume and the volume of the object. • C. The volume of the object is the sum of the initial volume and the final volume. • D. The final volume is the difference between the initial volume and the volume of the object. A. The final volume is the sum of the initial volume and the volume of the object

  8. 17 • Although they may not realize it, many people need scientific knowledge for their careers. An example is shown in the following illustration. How is this person using scientific knowledge? • A. by planning ahead • B. by using the proper tools • C. by taking the time to avoid mistakes • D. by using the metric system when measuring • D. by using the metric system when measuring

  9. 15 • This diagram shows one type of model of the brain. Which item represents another type of brain model? • A. a copy of the human skull • B. the results of a lie detector test • C. the results of an intelligence test • D. a three-dimensional brain x-ray • D. a three-dimensional brain x-ray

  10. 9 • The table shows how the theory of atoms has changed over time What do these changes show about the current theory of the atom? • A. It is good because it adapts to include new information. • B. It is good because it is from a reliable source. • C. It is bad because it is likely to change again. • D. It is bad because it does not match the original theory of the atom. A. It is good because it adapts to include new information

  11. 14 • Scientists need to know how gravity acts on a space shuttle so they can put the space shuttle into orbit. They use an equation that describes how gravity relates to the mass of two objects and the distance between the two objects. Which term describes this equation? • A. a scientific law • B. an observation • C. a model • D. a scientific theory • A. a scientific law

  12. 10 • Which of the following statements about scientific laws and theories is correct? • A. A law explains; a theory predicts. • B. A law describes; a theory explains. • C. A law predicts; a theory guesses. • D. A law is fact; a theory is a guess B. A law describes; a theory explains

  13. 13 • Which source should a scientific researcher reject because of unreliability? • A. textbook • B. government brochure • C. webpage of a university professor • D. advertisement promoting a product • D. advertisement promoting a product

  14. 6 • Raul wants to investigate how the angle of a ramp affects the speed of an object rolling down the ramp. He can conduct his investigation in a number of different ways.
