INSTRUCTIONAL PROCEDURES

PERIOD 1: Magnetism

NOTE

Magnets

A magnet is a body having the property of attracting iron and producing a magnetic field external to itself

Properties of magnet

1. It attracts magnetic substances.
2. It points North-South direction when suspended freely.
3. Repulsion is the surest test of magnetism.
4. Poles of magnet are always in pair.
5. Similar poles of magnet repel each other.
6. Magnetic force can easily pass through non-magnetic substances

Magnetic materials include iron, nickel, cobalt, and steel.

Non-magnetic materials include plastic, rubber, water, wood etc

Common uses of magnets and how to make magnets

1. A magnet is used in a compass to show the direction.
2. Powerful magnets are used to lift objects.
3. Magnets are used in generators and motors.
4. Prevents corrosion in a water heater. ...
5. Magnets are used in medical equipment.

How to make electromagnets

Materials

1. A large iron nail
2. 3 feet of thin coated copper wire
3. A D-cell battery
4. Small magnetic objects, like paperclips or pins
5. Wire strippers
6. Masking tape

Procedures

1. Strip the ends of the wire. Use the wire strippers to remove a few centimeters of insulation from either end of the copper wire. The uninsulated ends will be wrapped around the ends of the battery
2. Wrap the nail. starting about 8 inches from the end of the wire, wrap the nail tightly. Each wrap should be touching the last, but don't overlap them. Continue wrapping until the nail is covered from head to tip
3. Connect the battery. Wrap one end of the exposed wire around the positive side of the battery and the other end around the negative side of the battery. Use a small piece of masking tape to secure the wire in place on both sides

4. Use the magnet. Place the nail near a paperclip or another small piece of metal. Since the nail is magnetized, the metal will stick to the nail. Experiment with different sizes and weights to see how much strength your magnet has.

EVALUATION:    1. Explain the meaning of Magnets

2. Give three examples each magnetic and non magnetic materials
3. Write four common applications of magnets

                             4a. List materials used in making magnets

1. Outline the procedures in making electromagnet

CLASS ACTIVITY: Pupils in small groups, make simple electromagnet

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Swimming. Desktop publishing

NOTE

Meaning and basic skills in swimming

Swimming is the movement of the body in the water using the arms and legs to stay afloat

Basic skills in swimming

1. breaststroke
2. freestyle
3. Backstroke

EVALUATION:    1. Define swimming

2. Outline the skills in swimming

CLASS ACTIVITY: Pupils in small groups demonstrate the skills involved in swimming

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
