This experiment most likely tests the hypothesis that — A ramps made of wood make cars roll faster Bthe 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 Students placed two identical toy cars on these wooden ramps. The students let the cars roll down the ramps.

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?

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

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 BConsumers only C Both producers and consumers D Neither producers nor consumers

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

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

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? A4, 3, 2, 1 B1, 2, 3, 4 C1, 4, 2, 3 D4, 1, 3, 2

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 – Athe young of both organisms look like small adults Bboth organisms reproduce by laying eggs Cboth organisms change appearance as they mature Dboth organisms require damp soil to reproduce

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.

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

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

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.

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. J The car’s velocity increased as it traveled down the ramp.

Which experiment would best show how different methods of plowing fields on a hill affect erosion? A D C B

Magnet #1 Magnet #2

The two magnets above were placed near each other on the top of a table. If Magnet #1 is pushed slowly towards Magnet #2, which of the following will most likely be occur? AMagnet #1 will push Magnet #2 away. BMagnet #1 will pull Magnet #2 towards it. CThere will be no force between the magnets. DThe magnetic force will change the magnets. Magnet #1Magnet #2

An increase in the average level of carbon dioxide in the atmosphere is most likely caused by an increase in the — A extinctions of animals B plant life on Earth C number of large forest fires D number of solar-powered homes

Three soil samples were tested to see how much water each could hold. The same amount of water was added to each funnel of soil. Very few plants would probably grow in the clay because the water would — A fail to reach the roots of the plants B become too cloudy C run through the soil too quickly D become poisonous to the plants
