A B C D Touch Taste Sight Smell 18 Which of these foods would be the best choice for someone on a low-fat, low-sodium diet? F G Q R S T 16 This diagram shows layers of soil and rock from below a forest floor. Which of these conclusions is best supported by the information found in this diagram? F A body of water once covered the area. G The forest was made up of oak trees. Fish were the first animals in the area. The area was planted with trees one year ago. 5

7 19 Use the information above and your knowledge of science to help you answer Question. Rocks in the stream that the students were studying were smoother than rocks found in a nearby stream. The smoother rocks were most likely found in a stream where, over a long period of time, the water A was deeper C was cold B appeared cloudy D moved faster 20 Blowing through a pipe can produce a sound because the F air in the pipe vibrates pipe cools the air G pipe speeds up the air air is absorbed by the pipe 6

F G 29 The table shows the time it took to freeze water in two different salt solutions with different salt content. According to the table A freezing rates are the same in each trial C water loses heat at a rate of 1C per minute B water with more salt takes longer to freeze D salt dissolves more quickly in small amounts of water 10

12 30 Which of these questions can be answered from the results of this experiment? F Do beans need light in order to grow? Does seawater affect bean growth? G Can beans grow faster in groups of eight? ow much water is needed for beans to grow? 31 The diagram shows part of the water cycle. Which part of the diagram shows precipitation? A W C Y B X D Z 11
