One student adds 2 tablespoons of finely crushed table salt to a cup of room

temperature water. Another student adds 2 tablespoons of rock salt with large

crystals to a cup of room temperature water. Both students stir their solutions until all the salt dissolves.

How do the conditions in the cup affect the time it takes the salt to dissolve in each

cup?

• The rock salt has larger particles so it takes longer to dissolve.

• The table salt has more total particles so it takes longer to dissolve.

• Both cups of water are the same temperature so both types of salt will take the same amount

  of time to dissolve.

• Both cups of water contain the same amount of salt so both types of salt will take the same

  amount of time to dissolve.

Which factors determine the amount of Earth’s gravitational force on an object?

• the object’s mass and distance away from Earth

• the object’s shape and distance away from Earth

• the object’s speed and mass

• the object’s shape and size

A student fills three bowls with 1,000 milliliters of water at different temperatures.

The student places an 11-gram soup flavor cube in each beaker. The table shows the

time for the flavor cube to dissolve completely. If the temperature of the water is increased to 50°C, about how long will it take the

flavor cube to dissolve completely?

• 0 seconds

• 9 seconds

• 32 seconds

• 43 seconds

The table contains information about objects in space.

Which two objects are most likely comets?

• Object 1

• Object 2

• Object 3

• Object 4

• Object 5

The diagram shows 5 grams of liquid and 7 grams of a different liquid being poured into an empty beaker.

If both liquids are poured into the empty beaker, how many grams of liquid will be present?

• 5 grams

• 7 grams

• 10 grams

• 12 grams

A teacher shows students in a class a diagram of fossils in rock layers (A-G).

Which three students’ observations are correct?

• An earthquake could have caused layers A-E to tilt.

• The fossils in layer D are younger than the fossil in layer B.

• Moving water cut through layers A-E, causing a deep groove.

• Layer G is the youngest layer.

• Layer F is older than the fossil in layer C.

The diagram shows the strengths of forces acting on a box.

In which direction will the box move?

• up

• right

• down

• left

The image shows a remote-controlled car on a track.

The table contains information about the car as it completes four laps without

stopping. A lap is when the car moves from the starting line, around the track, and back to the starting line.

Which information allows a person to predict the time on the stopwatch at the starting line at the end of

Lap 5, and what will that time be?

• the direction of movement; 150 seconds

• the direction of movement; 125 seconds

• the lap time; 150 seconds

• the mass of the car; 125 seconds

The image shows a remote-controlled car on a track.

A person uses different wheel sizes and different track surfaces for an experiment.

The table shows the results from the experiment.

Which combination of changes causes the car to travel the slowest around the track?

• wood track and large wheels

• carpet track and large wheels

• wood track and small wheels

• carpet track and small wheels

Four students (W-Z) shine the same type of flashlight at their teacher. The flashlights

represent stars, and the teacher represents Earth. The teacher records the observed

brightness of the students’ flashlights in the table. The more marks, the brighter the

flashlight appears.

Based on the brightness the teacher sees, which student most likely represents the

Sun?

• Student W

• Student X

• Student Y

• Student Z
