The student uses only three of the materials available to build a complete circuit that conducts

electricity. Which THREE are necessary?

• battery to provide energy to the circuit

• light bulb to show that the circuit conducts electricity

• wire to connect parts of the circuit and conduct electricity

• switch to conduct electricity in the circuit

• compass to show that the circuit conducts electricity

How will the amount of thumbtacks picked up compared to plastic wrap change with each material?

• more

• fewer

• no change

Which investigation would provide evidence of a chemical change?

• Spray perfume into the air, and when the air and perfume mix, observe the change in odor that

  happens as they mix.

• Put an antacid tablet in water, and when the antacid and water mix, observe the bubbles that form as

  a new substance is created.

• Heat water in a pan on a stove, and observe the steam that forms as the state of matter of the water

  changes

• Blow air through a wand filled with soap solution, and observe the bubbles that form as the air

  becomes trapped.

• The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the

  constructive force of deposition because flowing water carries large rocks from far away and drops

  them along a river, making the banks taller.

• The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the

  destructive forces of weathering and erosion because flowing water breaks down rock and carries the

  small pieces downstream.

• The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by the

  destructive forces of weathering and erosion because flowing water breaks down rock and carries the

  small pieces downstream, but valley 2 was formed by the constructive force of deposition because

  flowing water carries large rocks from far away and drops them along a river, making the banks taller.

• The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by

  the constructive force of deposition because flowing water carries large rocks from far away and

  drops them along a river, making the banks taller, but valley 2 was formed by the destructive forces

  of weathering and erosion because flowing water breaks down rock and carries the small pieces

  downstream.

• The student’s claim is correct because water fills small cracks in rocks, freezes, and expands, making the cracks larger over time.

• The student’s claim is correct because the rock was carried from the top of the volcano to its base by a glacier, creating many cracks over time.

• The student’s claim is not correct because the rock was picked up by moving water and rolled against

  other rocks, smoothing its surface and causing cracks in a short period of time.

• The student’s claim is not correct because large cracks in rocks are caused when lava from a volcano

  covers the rock so its temperature rises and falls in a short period of time, causing it to break.

Based on the picture, which steps would produce the BEST model of how the Himalayas formed over time?

• step 1: Label one cardboard box as the Eurasian Plate.

  step 2: Label another cardboard box as the Indian Plate.

  step 3: Slowly push both plates toward each other.

  step 4: Observe and record how the sizes of both plates change when the edges push against each other.

• step 1: Use light-colored clay to make the shape of the Eurasian Plate.

  step 2: Use dark-colored clay to make the shape of the Indian Plate.

  step 3: Slowly push the dark-colored plate toward the light-colored plate.

  step 4: Observe and record how the shapes of both plates change when the edges push against each other.

• step 1: Use light-colored clay to make the shape of the Eurasian Plate.

  step 2: Use dark-colored clay to make the shape of the Indian Plate.

  step 3: Slowly push the light-colored plate toward the dark-colored plate.

  step 4: Observe and record how the shape of the Eurasian Plate changes when it touches the edge of the Indian Plate.

A student is studying the formation of the Himalayas. The student finds a picture and learns that the mountain range formed when the Indian Plate collided with the Eurasian Plate. The student uses a picture to design a model that will show classmates how the Himalayas formed.

step 1: Use light-colored clay to make the shape of the Eurasian Plate.

step 2: Use dark-colored clay to make the shape of the Indian Plate.

step 3: Slowly push the dark-colored plate toward the light-colored plate.

step 4: Observe and record how the shapes of both plates change when the edges push against each other.

Which data could the student collect using the BEST model from the steps?

• the changing distance between the two plates

• the time it takes for the two plates to collide

• the mass of the materials used to make the two plates

• the changing height of the edge where the two plates collide

Deposition of sediments can change the depth of a lake over time. A student wants to make a model that shows how this process takes place. Which model would provide data about changes in the depth of a lake caused by deposition?

• Fill a beaker with water. Slowly allow the water to evaporate from the beaker. Measure the change in the depth of the water.

• Fill a beaker with water. Slowly drop sand, gravel, and dead plant material into the beaker. Measure the change in the depth of the water.

• Fill a plastic box with water. Put a hose in the water on one end of the box and turn the water on to a slow flow. Measure the depth of the water when the box is full.

• Fill a plastic box with sand, gravel, and dead plant material. Put a hose in the middle of the box and turn the water on to a slow flow. Measure the depth of the water when the box is full.
