8CK SCI Mischief

8 CK SCIENCE Electric and Magnetic Mischief - COMPLETE

Electricity electric charges that flow through a wire or similar material
Magnetism the force of attraction or repulsion of magnetic materials
Electric charge a property of electrons and protons, electrons carry a negative charge and protons carry a positive charge
Electric Current the flow of electric charge through a material
Electric generator a device that uses motion and converts it into electric current
Conductors materials through which electrons move freely
Molten melted especially by intense heat
Alternating current current consisting of charges that move back and forth in a circuit
Step-up transformer a transformer that increases voltage
Electromagnet a strong magnet that can be turned on and off
Insulators materials through which charges of an electric current are not able to move freely
Step-down transformer a transformer that decreases voltage
Electric Current the flow of electric charge through a material
Magnetic poles the ends of a magnetic object, where the magnetic force is strongest
Van Allen Belts two doughnut-shaped regions that contain electrons and protons traveling at very high speeds
Attract to pull to or toward oneself or itself (electron-proton interaction)
Magnetosphere the region of Earth's magnetic field confined by solar wind
Voltage the difference in electrical potential between two places
Electric generator a device that uses motion and converts it into electric current
Electrical potential potential energy per unit of electric charge
Transformer a device that increases or decreases voltage
Electric motor a device that use electric current to produce motion
Navigation method of determining position, course and distance traveled
Magnetic Compass a device that has a magnetized needle that can spin freely, a compass needle always points north
Electric Current the flow of electric charge through a material
Ohm's Law ohms (resistance) = volts (voltage) / amps (current; R=V/I or I = V/R or V= IR

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.
