Circuits

8th Grade Science

Electric Circuit This needs at least a power source, a path for the electric current to flow, and a resistor such as a light bulb.
Series Circuit A circuit where the devices are connected one after the other. Electrons can only flow in one direction. If one device fails, the electricity stops flowing.
Parallel circuit A circuit that has multiple paths for electrons to flow. If one device fails, electricity can still flow through another path.
Electric current The flow of an electric charge through a conductor
Electric force The attraction between two electrically charged objects
Electrons The negatively charged particles in an atom
Conductor a material that electricity can flow through easily such as metal.
Insulator a material that electricity can not flow through easily such as rubber or plastic.
Load a device in a circuit that operates using electrical energy. An example of this is a lightbulb, motor, or radio.
Switch A device that is used to control the flow of current though a circuit. This device opens or closes the circuit.
Open circuit A circuit that is broken, and electricity will not flow.
Closed circuit A circuit that has a continuous path for electricity to flow.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
