Science Grade 5: Simple Circuit Question

A student wants to design a complete, simple circuit for a class project. The student has more materials available than are needed for the project. What does a complete, simple circuit require to work?

• wire and a switch

• wire and a light bulb

• wire, a battery, and a switch

• wire, a battery, and a light bulb

Which of the following are the necessary components of a simple electric circuit?

• Wire, a switch, and a light bulb

• Wire, a switch, and a battery

• Wire, a battery, and a switch

• Wire, a battery, and a light bulb

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.

Which of the following best demonstrates the process of deposition?

• Fill a beaker with water and let it sit uncovered for several days. 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.

• Pour water over a pile of soil and measure the amount of water that runs off.

• Pour water over a pile of soil and measure the amount of soil that is carried away by the water.

Which question can be asked to find out which characteristic is a learned behavior?

• Do all eastern box turtles like the same food?

• Do eastern box turtles in other states live for 50 years?

• Do eastern box turtles in other states have the same color of spots?

• Do all eastern box turtles hide in their shells when they are frightened?

Which of the following is a learned behavior in eastern box turtles?

• Do all eastern box turtles like the same food?

• Length of lifespan

• Physical characteristics

• Instinctive behavior

A student claims that both valleys have been formed by the same process over a long period of time. Which argument BEST explains why the student’s claim is correct or incorrect?

• 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.

A student wants to test some materials to find out whether they conduct electricity or insulate electricity. The student uses the following steps to get started. step 1: Attach wire 1 to the negative end of a battery. step 2: Attach wire 2 to the positive end of the battery. step 3: Attach the open end of wire 2 to a light bulb. step 4: Attach wire 3 to the light bulb. step 5: ________ What should the student do in step 5 to test a material for conductivity?

• Place the material to be tested between the open ends of wire 1 and wire 3.

• Connect wire 1 directly to the light bulb without using the material.

• Attach wire 3 to the positive end of the battery.

• Place the material to be tested on top of the battery.

• Observe whether the light bulb lights up to determine if the material is a conductor or insulator.

• Disconnect the battery from all wires and record the result.

• Replace the light bulb with another battery and check for changes.

• Remove the material and test the wires without any material in between.

The student has a variety of materials to test. Which steps would BEST complete the procedure and which conclusion should the student make?

• step 5: Connect a test material to the open ends of wire 1 and wire 3. step 6: Make observations, and repeat step 5 with a different test material. conclusion: If the bulb lights up, the material is a conductor. If the bulb does not light up, the material is an insulator.

• step 5: Connect a test material to the open ends of wire 1 and wire 3. step 6: Make observations, and repeat step 5 with a different test material. conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material is a conductor.

• step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit. step 6: Touch a test material to the completed circuit, and record observations. conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material is a conductor.
