Pictures and Diagrams

1. Pictures and Diagrams *The most important thing is to really pay attention to the pictures and diagrams and study them before and after reading the question!

9. Students placed two identical toy cars on these wooden ramps. The students let the cars roll down the ramps. This experiment most likely tests the hypothesis that — A ramps made of wood make cars roll faster B the height of the ramp affects the speed of the car C the speed of the car is determined by tire size D plastic cars travel faster than metal cars

11. A student has three different types of seeds. The student plants two seeds of each type against the side of clear plastic cups so that the seeds can be observed. All twelve cups are placed together in a sunny window, and each cup is given the same amount of water. The student records observations of the seeds at the same time every day in a data chart. Which question is the student most likely trying to answer? A Do seeds need sunlight in order to sprout? B Will seeds sprout faster in clear plastic cups? C How much water do seeds need in order to sprout? D Do some kinds of seeds take longer to sprout than others?

13. A C B D Which skull belongs to an animal best adapted for catching and eating fish?

15. Which group supplies food for other organisms? A Producers only B Consumers only C Both producers and consumers D Neither producers nor consumers Which group can live without water? A Producers only B Consumers only C Both producers and consumers D Neither producers nor consumers Which group changes light energy into food energy? A Producers only B Consumers only C Both producers and consumers D Neither producers nor consumers Which group depends on other organisms as a food source? A Producers only B Consumers only C Both producers and consumers D Neither producers nor consumers

17. The type of penguin shown in the picture above lives in the icy lands of Antarctica. The male penguins huddle together in a tight group. They stay in these tight groups most likely because they are — F looking for the sun G hiding from predators H sharing body heat J fighting over a piece of food

19. The pictures show the stages in the life cycle of a beetle. What would be the correct sequence for the development of the beetle? A Q, S, R, T B* R, T, Q, S C S, R, Q, T D T, S, R, Q

21. Some of the stages in the development of a dandelion are shown above, but they are out of order. What should be the order of the pictures? A 4, 3, 2, 1 B 1, 2, 3, 4 C 1, 4, 2, 3 D 4, 1, 3, 2

23. Compare the life cycle of the mayfly and the life cycle of the oak tree pictured below The greatest similarity between the life cycle of an oak tree and the life cycle of a mayfly is – A the young of both organisms look like small adults B both organisms reproduce by laying eggs C both organisms change appearance as they mature D both organisms require damp soil to reproduce

25. Water is heated in the glass bowl on the hot plate pictured above. What causes the bowl to become hot? A The air around the glass bowl conducts heat. B The glass bowl conducts heat from the hot plate. C The electricity from the hot plate conducts heat. D The radiant energy from the sun conducts heat.

27. A C B D All the are examples of light being refracted EXCEPT —

29. Which of these pictures shows the way to use a battery to light a bulb? A C D B

31. 13. What property of matter is illustrated in the picture? A Magnetism B Density C Viscosity D Boiling point

33. A student stirs together a mixture of hot water and small amounts of salt, sand, and sugar. The student then pours the mixture through a paper towel. Which substance or substances will collect on the paper towel? A Only the sugar B Only the sand C Both the salt and the sugar D Both the salt and the sand

35. This experiment shows how salt water can be boiled and made into freshwater. Which statement about solutions is supported by the diagram? A The parts of a solution must have the same boiling point. B A solution is made up of only one type of particle. C A solution is formed when a liquid changes into a solid. D The parts of a solution can be separated by a physical change.

37. 0 cm 5 cm 10 cm 15 cm 20 cm 25 cm Start 30 cm 1 second 2 seconds 3 seconds A car with its front end at the 0 position was released at the top of a ramp. The position of the car after 1 second, 2 seconds, and 3 seconds is shown above. What conclusion can be drawn about the velocity of the car as it traveled down the ramp? F The car’s velocity did not change as it traveled down the ramp. G The car’s velocity was constant as it traveled down the ramp. H The car’s velocity decreased as it traveled down the ramp.
