# Magnet Worksheet

The Magnet Experiments MatchCard leads students on an exploration of the poles of common magnets.

## Opposites Attract

Objective: Predict what poles of a magnet will be attacted or repelled by the pole of another magnet.

Let the student experiment with a set of common magnets. They will quickly find that one side of a magnet will either be attracted or repelled by one side of a different magnet.

Explain that the magnet has two poles: north and south. What else has two poles? (Earth)

Ask them to find a way to tell which pole is north and which pole is south.

This is MatchCard #3 of the Light and Energy Unit Study. Find more information on MatchCard Science below.

### Where Is North?

If a magnet hangs free on a string, it will automatically position itself so that its north pole is facing the Earth's North Pole.

Here is how you might find north with different types of magnets and string:
• Horseshoe magnet: Tie the string (yarn or tooth floss will also work) in the middle.
• Bar magnets: Line up two or more magnets so they attract each other. Put a string in the middle of them.
• Washer shaped magnets: Tie the string through the circle.

Extra challenge: Use two different types of magnets with each other to discover which sides repel and attract.

### How To Make a Compass

• Once you have found the north pole of a magnet, rub the end with a needle or straight pin. You have magnetized the pin.
• Fill a glass with water.
• Very carefully, without breaking the surface tension on the top of the water, lay the magnetized pin or needle on the water.
• Watch the needle move so it points north.

### Crazy Compass

Magnetize another pin or needle. Lay it next to the first needle in the water, being careful not to break the surface tension. Notice how they react.

## How To Use MatchCards

MatchCards make science concepts and corresponding vocabulary interactive. As students move the information pieces on the MatchCards they review the material they have already learned.

## Light and Energy Unit Study

Kids will be energized to learn more about how the world works as they learn about light, magnetic energy, heat energy, electrical energy, thermal energy, kinetic energy and more. .

## 12 Science Unit Studies

Chemistry is only one of twelve complete unit studies for kids in 3rd to 8th grade.

Comprehensive objectives, hands-on projects, suggested science fair experiments, and the fun game-like MatchCards keep them interested in learning science. See all twelve MatchCard Science Unit Studies.
