Content: Physical Science

Objectives:
Ã‚Â·Students will be able to locate poles on various kinds of magnets
Ã‚Â·Students will be able to identify the strongest parts of a magnet.
Ã‚Â·Students will be able to observe that like poles repel and unlike poles attract each other.
Ã‚Â·Students will be able to identify objects that magnets attract.

Materials:
Magnets (both man-made and natural magnets)
Paper Clips
Iron Filings
Plain White Paper

Vocabulary:
Magnets- A stone or a piece of metal that attracts some other metal.
Attract- To pull towards.
Repel- To push away from each other.
Magnetic Poles

Procedures:

Anticipatory-
1.Tell the students that today we are starting a new unit in science.
2.Hold up a magnet.
a.Ask if anyone knows what it is?
3.Show students a bar magnet.
a.Ask them what the S and N stand for?
4.Explain that all magnets have a north and south pole.
a.Just like our earth.
b.Can anyone name something that shows us the directions north and south?
c.Has anyone ever heard of a compass?

Continuation-
1.Show the students actual examples of magnets.
2.Give each pair of students two magnets and tell them to find the poles.
3.Demonstration-
a.Give each pair of students’ paper clips and have them lay them in a line.
b.Touch a magnet to one paper clip.
i.Now the paper clip is temporarily magnetic.
c.Lower the magnet until the paper clip is touching another.
d.Lift the magnet up again
i.Lets see who can get the longest chain.
e.Pull the plane off the table using a magnet.

Closure-
1.Hold up a magnet and ask the students the names of the poles and to name the strongest parts.
2.Ask a student or a pair of students to demonstrate and explain what two north poles do and what two south poles do.

Assessment:
1.Observe the students’ knowledge on locating the poles on various kinds of magnets.
2.Observe the students working with like and unlike poles.
3.Observe the students identifying the strongest parts of a magnet.
