STAAR Review

• travels in straight lines and reflects from the surface of the mirror

• enters the mirror and changes direction when it is refracted by the back of the mirror

• refracts in the glass of the mirror and is spread out all over the room

• travels through air and does not change its direction in air

The picture below shows a cumulonimbus cloud forming over an ocean. Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?

• Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• Light from the sun shines on the ocean, causing water vapor to condense. The water then evaporates to form a cumulonimbus cloud.

• Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

Which statement best describes the processes of weathering and erosion?

• Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.

• Weathering and erosion are directly responsible for the breakdown of any type of rock into smaller particles and the carrying away of the loose sediments.

• Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.

• Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.

A student places 250 g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100 mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot.What property of soils is the student most likely examining with this procedure?

• The amount of time it takes different soils to dry

• How well different soils retain water

• How much water is needed to dissolve different soils

• The differences in texture between wet and dry soils

The diagram shows a view of a ball from above a table. The ball is rolling across the table. A student lightly taps the rolling ball in the direction shown in the picture. In which direction does the ball most likely move after the student taps the ball? (3.6B)

The picture shows a pulley system that can be used to lift a box. Which of these should a person do to lift the box? (3.6B)

• Tie the end of the rope to the box

• Tie the end of the rope to the ceiling hook

• Pull the end of the rope downward

• Allow the end of the rope to move upward

Two students are playing on a swing set. Student 1 is leaning back and extending her legs as she moves upward. Student 2 is sitting on the swing with his feet on the ground. Which statement describes how position and work are related in this picture? (3.6B)

• Both students are doing work even if only one student is changing position.

• Student 1 is changing position because work is being done on the swing.

• Work done by Earth's gravity prevents Student 2 from changing position.

• Work is being done on both students by the swings because one swing is changing position.

The two pictures show part of an investigation. A magnet, a book, and a paper clip are on a sheet of lined paper. In Picture 1 a student slides a magnet closer to the book. The student holds the book still in both pictures. Which statement about this investigation can be supported by the result shown? (3.6B)

• Work was done on the magnet, the book, and the paper clip.

• Work was done on the magnet and the paper clip only.

• Work was done on the magnet and the book only.

• Work was done on the magnet only.
