Developing Science, Technology, Engineering, and Math Skills: THE STUDY OF MAGNETIC FORCE

Johnson Elementary Magnet School Assistance Program (MSAP) Project

The Force of Magnetic Attraction

### Magnetic Attraction

• How can the strength of the force of attraction between two magnets be measured?

• How does the distance between two magnets effect the strength of the force of attraction?

FOSS Activity:Investigation 1: The Force, Part 3: Breaking the ForceStudents in grade 4 investigated the strength of the force of attraction by graphing data to look for patterns of interaction.

Students use a balance and large washers to measure the force of attraction between two magnets.

They learn what happens to the force of attraction as the distance between the two magnets increases.

Students graph their results.

### Student Work

Engineering is Elementary

The Force of Magnetic Repulsion

### Magnetic Repulsion

• How can you make one magnet levitate above the other?

• Why are the magnets levitating?

• Why do you think adding more magnets affects how high they levitate?

Engineering is Elementary activity:Lesson 3, A magnetic personalityStudents in grade 4 engineering lab learned that increasing the magnetic field can intensify the magnetic forces of repulsion. They learn that non-magnetic materials do no affect magnetic fields.

### Students use a ruler to measure the height of the top of the magnet(s) above the table.

Students list three properties of magnets they observed during the magnetic levitation investigation and explain how each property helped levitate the magnets.
