3 1 The students brought in some river water for science class. The students saw algae and some small insects in the river water. The students also believed that the river water contained bacteria. Which of these tools could be used to find bacteria in river water? A Balances B Magnifying glass C Droppers D Microscope Page 2

4 Class A Experiment Class B Experiment Texas Education Agency Two classes set up an experiment to study whether ants prefer light or dark. Class A decided to set up their experiment in a T-shaped box. The ants could choose the top of the T-shaped box which was either shaded or bright. Class B went outside to an ant hill to observe the preference of ants. Results: Class B concluded that ants prefer light because there were 5 ants on top of the ant hill. Class A concluded that ants prefer light because all 4 ants went to the light side of the T-shaped box. 2 Which is the best conclusion from the evidence and information given above? A Class B has a better conclusion because it was done in the ant's environment. B Class B has a better conclusion because 5 ants were used instead of 4. C Class A has a better conclusion because ants may be inside the nest in experiment B. D Class A has a better conclusion because 4 ants were used instead of 5. Page 3

28 A student turned in the following report to his teacher. The Effects of Oceans on Land Oceans cause many changes to the land. The most common change is the wave action which causes beach erosion. There are currents in the ocean which move warm water into areas close to land. The air over the water also flows over the land warming the land. Snowfall in San Antonio is a frequent change in January caused by oceans. Another change the ocean has on land occurs when we experience high and low tides. 38 Which statement is NOT correct as "An Effect of the Ocean on Land"? A The most common change is the wave action which causes beach erosion. B The air over the water also flows over the land warming the land. C Snowfall in San Antonio is a frequent change in January caused by oceans. D Another change the ocean has on land occurs when we experience high and low tides. Page 27

29 Use the following paragraph about wind to answer Question 39 What is Wind? Wind is caused by the uneven heating of the Earth's surface. Since the Earth's surface is made up of land and water, the surface absorbs the heat differently. During the day, the air above land heats more quickly than air above the water. The warm air over land expands and rises. The heavier, cooler air rushes in to take its place, creating winds. 39 What is the source of heat which causes the winds? A Solar energy B Chemical energy C Atmospheric energy D Sound energy Page 28
