Science - 5th Grade
Students will understand that magnetism can be observed when there is an interaction between the magnetic fields of magnets or between a magnet and materials made of iron.
Describe how the magnetic field of Earth and a magnet are similar.
A Magnetic Personality
Students investigate how many paper clips different types of magnets can pick up.
Magnetic Fields of Magnets
The students will be able to compare the magnetic fields of various
types of magnets (e.g., bar magnet, disk magnet, horseshoe magnet.) Also they will compare
Earth's magnetic field to the magnetic field of a magnet.
After hanging horseshoe magnets, students will predict what will happen when the north end of their bar magnets are placed near the north end of their hanging magnets.
Magnets are attracted to certain metals and other magnets.
Students feel the attractive and repulsive forces of magnets. Students can
observe a magnetic force field by lining iron filings up with magnets. The north
and south poles of a magnet can be determined by comparing them to the
Earth's magnetic field. Magnetizing a needle and floating it on water makes a
floating needle compass.
Magnets in a Bag
Students will compare and contrast the patterns that they create using iron fillings and different types of magnets.
TRB 5:3 - Activity 5: Discovering Magnetic Fields
Students will complete a number of activities to learn about magnetic fields.
TRB 5:3 - Activity 6: Making a Magnet / Compass
Students will construct a compass and explain how it works.
TRB 5:3 - Activity 7: Finding Magnetic Fields of Earth
Students will investigate the effects of magnets on the needle of a compass and compare this to the effects of Earth's magnetic field on the needle of a compass.
The Earth and the Compass
Students make a water compass by using a needle and a bar magnet.
Students will use a needle and a magnet to create a compass
