Which change would weaken the electromagnet?

• Replace the copper rod with an iron nail.

• Remove some of the wire loops around the copper rod.

• Connect another battery between the switch and the copper rod.

• Use larger paper clips.

A student places a straw in a glass of water. The student observes that the part of the straw that is outside of the water looks different from the part of the straw that is in the water. Which statement best explains why the part of the straw that is out of the water appears different from the part of the straw that is in the water?

• The water causes visible light to reflect slowly, which causes the straw in the water to appear larger.

• Light travels through air and water at different speeds, which causes the straw to appear distorted in water.

• The water absorbs visible light, which causes the straw to appear in a different position than it does out of the water.

• Light is affected by the temperature difference between the air and water, which causes the straw to appear distorted in water.

A student investigated how temperature affects the current produced by a motor. The student separated three magnets used within the motor and cooled each magnet to 0°C. The strength of each magnet was tested by counting how many washers each magnet could pick up. Then each magnet was heated to a higher temperature and the testing with the washers was repeated. The student recorded the results in the data table. Under which conditions would the motor produce the greatest amount of current?

• cooling the motor to keep the internal temperature between 10°C and 20°C

• cooling the motor to keep the internal temperature between 30°C and 40°C

• heating the motor to keep the internal temperature between 60°C and 70°C

• heating the motor to keep the internal temperature between 80°C and 90°C

Scientists observe that most galaxies are moving away from Earth. The farther away the galaxy is, the faster it is moving away from Earth.

Which two arguments are supported by the evidence that most galaxies are moving away from Earth?

• The universe used to be larger in the past.

• The universe used to be smaller in the past.

• The universe has always been the same size.

• The space between galaxies is becoming larger.

• The space between galaxies is becoming smaller.

Scientists have been researching finch populations in the Galapogos Islands for many years. In 1977, there was a drought in the area. The scientists compared data collected in the years before and after the drought to make a conclusion about the effect the drought had on finches.

Which of these is the most likely conclusion the scientists made after studying the data in the graphs?

• Finches that had beaks longer than 10 millimeters did not survive the drought of 1977.

• Finches that had beaks longer than 11 millimeters had already become extinct by 1976.

• Finches that had beaks between 10 and 11 millimeters long were better adapted to the environment on the islands in 1977 than finches that had different beak sizes.

• Finches that had beaks between 10 and 11 millimeters long were less abundant on the islands between 1976 and 1978 than finches that had different beak sizes.

The diagram represents the position of a dog at different times while it is running. Which statement best describes the dog's motion?

• The dog is speeding up.

• The dog is moving with a constant speed of 5 meters per second.

• If the motion of the dog stays the same, the position will be 120 meters when the time is 60 seconds.

• If the motion of the dog stays the same, the position will be 110 meters when the time is 60 seconds.

Using the maps, on which two pairs of continents would similar fossils be found?

• South America and Australia

• North America and Australia

• Asia and Australia

• Africa and South America

• Europe and North America
