Georgia Milestone Physical Science Review

A student observes some effects of electricity. The student records these observations in the following table. What should the student record in place of letters P and Q in this table?

• electric current for both P and Q

• static electricity for both P and Q

• electric current for P and the static electricity for Q

• static electricity for P and electric current for Q

How is an electromagnet different from a bar magnet? Select TWO answers.

• An electromagnet has only one pole.

• An electromagnet does not attract iron.

• An electromagnet can be turned on and off.

• An electromagnet is created by electric current.

• An electromagnet does not have a magnetic field.

Students in a science class make models of deposition. What do their models show?

• How lava flows from volcanoes

• How rocks are broken into particles

• How rock particles build up new landforms

• How water, ice, and wind move rock particles

A student is hiking on a summer day. She sees pieces of rock fall down a cliff. Which process MOST LIKELY occurred?

• erosion by water

• weathering by ice

• erosion by gravity

• deposition by wind

A student drops some nails into a trash can half filled with wood shavings. Which is a way to separate the mixture of nails and shavings?sifting

• sifting

• flotation

• evaporation

• using a filter

A chemical change is indicated in the model by...

What happens during the process of erosion?

• Sediment forms.

• Sediment is moved.

• Sediment is dropped.

• Sediment hardens into rock.

Electricity and magnetism are connected to each other. Electricity can produce magnetism. When an electric current flows through a wire, the current creates a very small magnetic field.

• True

• False

• 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.

• 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 a conductor. If the bulb does not light up, the material

  is an insulator.
