Prior to beginning the lesson: (1) Cut out and laminate Vocabulary Cards
for display in the classroom. (Allow 20-25 minutes for instruction time.)
Students will be able to:
(see attachment), What Makes a Magnet?
by Franklyn M. Branley, two magnets, string, marker, compass
Read the story What Makes a Magnet? by Franklyn M. Branley out loud to the class. Ask students: What are the ends of a magnet called? Why are they called north-seeking and south-seeking?
Display Vocabulary Cards "north-seeking pole" and "south-seeking pole".
Tell students: Today we are going to use a magnet and to find out which pole is north-seeking and which pole is south-seeking.
Tie a string around the middle of a magnet and hang it from a table at the front of the room. Hold a compass up next to the magnet to determine which end is pointing north. Tell students: This is the north-seeking pole. Use a marker to mark “North” and “South” on the magnet.
Repeat the same procedure with another magnet.
Next, choose a student to come to the front of the room, and have him put the magnets next to each other so that the like poles are facing. Ask the student: What is happening? What do you feel?
Display Vocabulary Card "repel". Make sure students understand repel is to push away.
Call a few more students up to feel the magnets repelling one another.
Next, choose another student to come to the front of the room, and have him put the magnets next to each other so that the unlike poles are facing. Ask the student: What is happening? What do you feel?
Display Vocabulary Card "attract". Make sure students understand attract means go towards each other.
Call a few more students up to feel the magnets attract.
Tell students: We will continue to experiment with north and south poles tomorrow.
Modifications: For students with special needs, provide one-on-one assistance as necessary.
Have students turn to a partner and tell the one thing they learned about magnets today.
