5 DIRECTIONS Read each question and choose the best answer. Then fill in the correct answer on your answer document. SAMPLE A When a 10% hydrochloric acid solution is heated in an open test tube, the test tube should always be pointed A so bubbles are visible B at a 180 angle from the frame C toward a ventilated area D away from nearby people SAMPLE B Mass = 40 g Volume = 20 ml The picture shows a cube that contains 20 ml of a solution. The solution has a mass of 40 grams. What is the density in g/ml of this solution? Record and bubble your answer on the answer document. Page 3

7 2 A student has decided to enter a science fair. For the project the student elects to determine which type of golf ball will roll down a ramp and across the floor the farthest distance. Which design would be the best way for the student to conduct this experiment? F Start each golf ball from a different height on the ramp, measure the distances traveled, and graph the results. G Make several trial runs for each ball using ramps of different heights, record the distances traveled, and graph the results. H Using the same ramp height, make several trial runs for each ball, record distances traveled, and graph the results. J Drop each ball from different heights onto the ramp, measure distances traveled, and graph the results. Page 5

8 One piece of equipment students use in the science classroom is a triple beam balance. The balance allows the students to determine the mass of objects. The above drawing shows the three arms of a triple beam balance being used to find the mass of an object in grams. What is the most precise measurement that can be made with this balance? A 100g B 10g C 1g D 0.1g Page 6

9 Speed of Sound in Air Air Temperature Speed of Sound 0 o C? m/s 25 o C 346 m/s 50 o C 361 m/s 100 o C 391 m/s 4 The speed of sound in air is directly proportional to the temperature of the air. If the temperature of the air increases, the speed of sound also increases. For every 10 o C increase in air temperature the speed of sound increases by approximately 6 m/s. What is the expected speed of sound in air at 0 o C?

D The child has a zero chance of expressing the defect. 2005JupiterImagesCorporation 12 A surfer is riding the waves not far from the shore. As he catches a wave he is pushed forward and upward. As a larger wave reaches the surfer he is pushed higher. What wave characteristic accounts for the change? F The larger wave has more amplitude. G The larger wave has a longer wavelength. H The larger wave has a higher frequency. J The larger wave has less friction. Page 9

12 (1) (2) Some images 2005 JupiterImages Corporation 13 The pictures show two levers being used to lift the same rock to the same height. Why should a person select to use the lever set-up shown in drawing (2)? A Less work is required to lift the rock. B Less time is required to lift the rock. C It gives you more mechanical advantage. D It transferred more energy to the rock. 14 Which of the following genetic crosses is expected to produce the most variations? T = tall t = short S = wide s = thin F TT x SS G Tt x SS H tt x SS J tt x Ss Page 10

13 15 A student wanted to know if the color of a can affected how fast hot water would cool down. The student filled three equal size but different colored cans with the same amount of boiling water. The temperature of each can was taken every five minutes for 60 minutes. The graph shows the results of the experiment the student conducted. What is a valid conclusion that can be made based on the experimental results? A Lighter colored cans cool faster than darker colored cans. B Darker colored cans cool faster than lighter colored cans. C Each can cooled at the same rate regardless of its color. D Metal cans should cool down faster than plastic cans. Page 11
