Magnet lesson

Magnets 

Savannah saw a paper clip at the bottom of a shallow puddle of water.

She used a magnet to remove the paper clip without getting her hands

or the magnet wet.

Explain how this is possible.

Teacher NoTes:

Use this assessment after teaching Lesson 3.

Consider using this performance task with older children and the performance task titled “What Magnets Work Through” on page 30 with younger children.

You might administer this task orally, individually, or in small groups.

evaluaTioN GuideliNes:

When evaluating children’s responses, look for the following elements:

•             Magnets can pull on an object without touching the object.

•             The force of a magnet can work through water.

Some children might also mention that the force of a magnet can work through air.

If needed, guide children to think about how the magnet was used. You might prompt them with questions such as the following:

•             Does a magnet need to touch an object in order to move an object?

•             Can the force of a magnet work through water and air?

What Are The Types of Magnets?

Types of Magnets

There are two major types of magnets: Permanent magnets and Temporary magnets. 

Permanent magnets retain their magnetism over a long period of time whereas temporary magnets retain their magnetic properties only under certain conditions like presence of a strong magnet or an electric current in the vicinity.

Magnets are available in different shapes as well. For example, bar magnets, horse-shoe magnets, magnetic needles, ring magnets or disc magnets.

Magnets Can Attract Or Repel Each Other.

When will magnets attract or repel each other?

The rule to remember is that opposites attract.  Every magnet has both a North and a South pole.  When you place the North pole of one magnet near the South pole of another magnet, they are attracted to one another.

When you place like poles of two magnets near each other (North to North or South to South), they will repel each other.

1. When different poles of two magnets face each other, the magnets will attract.

2. When the same poles of two magnets face each other, the magnets will repel.

What Materials Do Magnets Attract?

What is attracted to magnets?

 

This video shows that a Junior Science teaching and learning reource to enable students to engage with magnetic and non-magnetic materials and resolve any misconceptions/preconceptions.

Magnets Can Attract Magnetic Objects.

A. MAGNETIC OBJECTS.











Steel Spoon

  







Iron Nail

Thumbtacks

Objects that are made of iron, steel or nickel can be attracted by magnets. They are called magnetic objects.

Magnets Cannot Attract Non-Magnetic Objects.

B. NON-MAGNETIC OBJECTS.

Eraser









Glass

Gold Ring

Plastic Ruler

Objects that are made of wood, plastic, glass or gold cannot be attracted by magnets. They are called non-magnetic objects.
