Georgia Milestone Physical Science Review

Insulators are any type of object through which an electric current cannot flow. Glass, plastic, and rubber are very common insulating materials. Insulators are used to protect people from electric currents.

• True

• False

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

• Magnet 1 should be used to pick up many small magnetic objects at once because the temporary magnet can pick up as many objects as the permanent magnet can.

• Magnet 1 should be used to pick up magnetic objects in one location and drop them off in another location because temporary magnets can be turned on and off.

• Magnet 1 can be used in all the ways magnet 2 is used because temporary magnets can be made stronger or weaker and permanent magnets cannot.

• Magnet 2 should be used to pick up magnetic objects in places where there is no power supply because permanent magnets do not run out of energy.

• Magnet 2 should be used to pick up large magnetic objects because permanent magnets are stronger than temporary magnets.

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

• more

• fewer

• no change

A student is investigating chemical changes by using different materials. Which investigation would provide evidence of a chemical change and why?

• Melting a solid with fire would provide evidence of a chemical change because the solid would change

  shape.

• Cutting cardboard into many smaller pieces would provide evidence of a chemical change because the

  pieces cannot be put back together.

• Placing a solid into hot water and stirring while the solid dissolves would provide evidence of a

  chemical change because the dissolved material is lost.

• Combining two liquids that give off heat and gas would provide evidence of a chemical change because

  the particles react to make a new material with different properties.

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.

Students are investigating chemical changes that occur in different materials. Which TWO investigations would provide evidence of a chemical change?

• Placing a liquid in a freezer until the liquid becomes a solid would provide evidence of a chemical

  change because the state of matter changes.

• Using a saw to cut a solid into two different pieces would provide evidence of a chemical change

  because the pieces cannot be put back together.

• Using a hot plate to heat a solid until it changes color and releases an odor would provide evidence of

  a chemical change because the particles cannot be changed back.

• Placing two different liquids together in a beaker and observing that a solid forms when they mix would

  provide evidence of a chemical change because a new material is formed.

• Placing a mixture containing a solid and a liquid on a windowsill and letting the liquid evaporate would

  provide evidence of a chemical change because the evaporated material is lost.

If Kayla burns wood in a fire, this is a ____ change

• There is no change the wood is still wood

• A physical change the wood is just breaking down

• A chemical change the wood is becoming a new substance

• The fire actually is the thing that changes and it takes on a chemical change

What is a parallel circuit? 

• A circuit with only one path to get electricity to the light

• A circuit without any paths to get electricity to the light

• A circuit with multiple paths to get electricity to the light

• I never knew there was such a thing as a parallel circuit
