8 7 During a science lab, a group of students tested different items in both saltwater and freshwater to see which items would float and which items would sink. After seeing a plastic bead sink in the freshwater and float in the saltwater, one student remarked, "The bead is heavier in the freshwater." Her classmate pointed out that - A there was not enough buoyant force in the freshwater to keep the bead afloat B there was not enough buoyant force in the saltwater to keep the bead afloat C the buoyant force in the freshwater is equal to the buoyant force in the saltwater D the bead is heavier in the saltwater than it is in the freshwater 8 Suppose you conduct an experiment using batteries in a flashlight. You record the data in the chart below. Brand of Battery Brand A Brand B How long did the flashlight produce light? 3 hours 4 hours Which of the following inferences can you draw from your experiment? F The light bulbs used with Brand A are brightest. G The light bulbs used with Brand B are brightest. H Brand A batteries last longer than Brand B batteries. J Brand B batteries last longer than Brand A batteries. Page 6

9 Use the diagram below to answer questions 9, 10, and 11. North Cup West East South 9 A teacher uses the stream table shown above to show erosion and deposition as the stream flows. Which of the following is an example of a limitation of this model? A It does not have any fish in the stream or water. B It does not show how water can flow uphill. C It does not show the different temperatures of erosion. D It does not show how two rivers can join together. 11 What is the role of the cup in the stream table model pictured above? A The sound source B The light source C The river source D The ocean source 10 A stream table like the one shown above was used to show the flow of soil when water is poured on it. In which direction did the soil move? Towards the - F North G South H East J West Page 7

10 Temperature in C C 14 In the science lab, a student conducted an experiment to see what would happen when a small amount of hot, blue colored water was added to a large cup of clear water at room temperature. She noticed that the blue water floated on top of the clear water. This happened because F the blue water got hotter after it was poured in the cup G the water in the cup got colder after the blue water was added H the hot, blue water is denser than the clear water in the cup J the clear water in the cup is denser than the hot, blue water 12 The above Celsius thermometer represents a good temperature for F swimming in July G harvesting pumpkins in October H building a snowman in January J planting tulip bulbs in February 2005 JupiterImages 13 An electric circuit consists of a battery, wire, and a motor that spins. When the wire is removed, the motor will - A stop spinning B start buzzing C spin faster D burn out 15 You make a glass of lemonade and add some ice cubes to it so that the glass is completely full. What states of matter are contained in your glass? A Solid and gas B Gas and liquid C Gas and solid D Liquid and solid Page 8

11 Magnetic Compass Bar Magnet Some images 2005 JupiterImages Corporation 16 A student was working with a bar magnet and a compass like the ones pictured above during science class.

12 17 You are on an airplane going over a mountain range in Colorado. You notice the large, pointed horn of a mountain. You remember reading in science class about valley glaciers.

14 Use the information in the following paragraph to answer questions 22 and 23. You and your friends are out on the playground after a short rain shower. On the sidewalk, you notice a puddle of water. You decide to draw a circle around the puddle of water with a piece of chalk. When your class comes out for P.E. later in the day, you notice that the puddle is smaller than the circle you drew, so you draw a new circle around the smaller puddle of water. After school, you check the puddle again. You see that the puddle has gotten smaller again. 22 The pattern you have observed in the puddle of water is caused by - F evaporation G condensation H melting J weathering 23 What source of energy caused the changes that you observed in the pattern of circles you drew on the sidewalk? A Sound B Electricity C The Sun D Chemicals Page 12
