Standards
• 4.PS.3.2(Priority Standard)
Make observations to show that energy can be transferred from place
to place by sound, light, heat, and electric currents.
What are we going
to learn today?
• I can define a conductor and an
insulator.
• I can investigate about conductors
and insulators.
• I can relate real life examples of
conductors and insulators.
Let's Investigate !
• Go to this
simulation: https://simpop.org/conductivity/conductivity.htm
• Follow the directions provided in the simulation.
• Depending on your assigned group answer to the questions.

8-Using the simulation, define a
conductor and insulator.
5- Using the simulation, define a

After investigations!
• A material that allows electric current to flow through it is called a
conductor.
• A material that does not allow electric current to flow through It is
called an insulator.
• Metal is a good conductor of electricity. For that reason, copper is a
metal that is used to make electric wires.
After investigations!
3. The paper clip is the better conductor because the carboard is an
insulator. The cardboard does not allow electric current to flow
through it .
6.The problem is that the connectors used do not allow the electric
current to pass. They are insulators.
7. The electric wire must allow electric current to flow , but it should
only flow in the wire. The outside covering keeps the current in the
wire.
After investigations
• An electric current is open when an insulator is connected to the
circuit.
• An electric current is closed , when a conductor is connected to the
circuit.
