Lesson 5: Magnets 5
Duration of Days: 1
Lesson Objective
1. Students will use a simulation to model how magnetic fields change when a second magnet or coil is added to the system.
2. Identify an "Attractive Field": They will show how field lines connect in the middle when North and South poles meet.
3. Identify a "Repulsive Field": They will show how field lines curve away from each other when two similar poles meet.
4. Create a diagram model (a shared "map") to represent these invisible interactions accurately.
How does the magnetic field change when we add another magnet to the system?

Description:
Students will use a computer simulation to look at the invisible fields between two objects (like a magnet and a coil). They will observe what happens to these fields when they are pulling together versus pushing apart at different distances.
Purpose:
To help students visualize why magnets move. By seeing the field lines connect or curve away, students can explain the "how" behind the attraction and repulsion they felt in earlier hands-on labs.
DOK level 3
For Visual Learners: Students will use color-coded pointers in their drawings—one color for lines that "connect" and another for lines that "push away."
For Tech-Support: We will provide a simulation "map" that gives students specific coordinates to move the magnets, ensuring they see the field change clearly.
For Vocabulary Support: Students will use "Connection" vs. "Avoidance" as everyday terms to describe the field lines before moving to scientific terms like attraction and repulsion.
-
The Interactive Lab Report: Ability to describe the difference between the "connecting" lines of attraction and the "curving" lines of repulsion.
-
Consensus Modeling: Assess if students can explain why the field lines don't look the same as they did for a single bar magnet.
-
Distance Comparison: Students describe the difficulty of seeing changes at different distances.
- Formative assessment
