Oregon Science Standards:
1. 5th Grade
2. Core Standard - 5.2 Interaction and Change: Force, energy, matter, and organisms interact
within living and non-living systems.
3. Content Standard - 5.2P.1 Describe how friction, gravity, and magnetic forces affect objects
on or near Earth.
Science Content (Direct Instruction):
Describe the science: Magnetic poles that are alike repel each other and magnetic poles that are
unlike attract each other. Magnetic field lines spread out from one pole, curve around a magnet
and return to the other pole. In a magnetized material, all or most of the domains are arranged in
the same direction. Magnets are destroyed by disorganizing the alignment of the atoms. This
can be done by hitting it hard or heat. Breaking it just creates smaller magnets
Vocabulary words:
Magnetism – the attraction of one object for another object
Magnetic Pole – the area of a magnet where the magnetic effect is strongest
Magnetic field – the region of magnetic force around a magnet
Atom – smallest particle of an element
Nucleus – the center of every atom and carries a positive charge
Electrons – tiny particles that orbit the nucleus and carries a negative charge
Magnetic domain – a cluster of billions of atoms that are lined up in the same direction
Ferromagnetic material – a material that shows strong magnetic effects (eg. Iron, nickel, cobalt)
Objective(s) of Activity:
1. Students will be able to describe how magnetic forces affect objects on Earth
2. Recognize patters of magnetic fields

PowerPoint
12 Cups of Iron Fillings
4 Cups of Objects
12 Large Sheets of Paper
The Action (Procedure):
Ferromagnetic materials
1. Use PowerPoint to explain what magnetism and ferromagnetic means
2. Predict which 8 objects in a cup are ferromagnetic material
3. Experiment with prediction results
4. Use hand-out to record observation
5. Ask if there are any characteristics that give us clues about if an material is ferromagnetic
PowerPoint instruction
1. Explain other definitions and what makes a material magnetic
Drawing magnetic fields activity
1. Place magnets under a paper and lightly sprinkle the paper with iron filaments
2. Have students record and draw observations
Pencil object lesson
1. Demonstrate how magnetic fields overcome the earth’s gravitational force
Questions
Tying Ideas Together: These are (10) questions that help to expand the lesson or motivate the
participants to think/reflect upon what they are learning.
Where is the magnet?
What objects are ferromagnetic?
Are there any characteristics that give us clues about if a material is ferromagnetic?
What part of this magnetic looks strongest?
What do you think happens to a magnet if you break it in half?
Look at this picture, can you predict which material will be magnetic? Which material will
be non-magnetic?
Assessment: These are (5) questions or other means which you can use to check (assess) how
well the participant learned the material. Usually the assessment is focused on how well the
objectives were met. If all the objectives were learned, then it is assumed that the goal of the
lesson was accomplished.
Handouts: Include all materials (e.g. data collection sheets or drawing/recording sheets or worksheets)
students will be using to complete the activity and/or lesson.
Safety Considerations
Don’t touch your face after you touched the Iron Fillings. Remember to wash your hands afterwards.
Don’t let the magnets get to close to the electrical outlets.
Be careful to not pinch you fingers with the magnets.
Don’t eat the Iron Fillings.
Reading and Writing Integration:
Students can have a take home assignment where they are instructed to go home and find things that
are ferromagnetic. They will write a short paper describing what they found at home.
Second option: Students can write up a short story integrating key vocabulary terms.
