Grade 5 Science · World 9: Magnet Mountain · Level 63
Thicker and Thinner
Investigate how thickness and distance change the pull.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 63
- Does thickness matter? Thin wood lets the magnet hold the clip.
- Thick wood doesn't. The wood isn't blocking the field. It just keeps the magnet too far from the clip.
- Distance is what matters. The field gets weaker as you go farther from the magnet.
- Scientists test it with numbers. Add one card at a time, and count how many clips the magnet holds.
Georgia Standards of Excellence in Science:
- S5P3.b — Plan and carry out an investigation to observe the interaction between a magnetic field and a magnetic object. (Clarification statement: The interaction should include placing materials of various types (wood, paper, glass, metal, and rocks) and thickness between the magnet and the magnetic object.)
