Below are sample questions representative of the exercises included on this worksheet and related 3.7 Use Magnets to Solve Problems skill assessments:

Problem 1Difficulty: Mastery

What is the best optimization plan?

AMake it even stronger so no one can open it.

BMove the magnet slightly farther from the metal plate (or use a small spacer) and retest until it holds >= 8 shakes.

CReplace the latch with glue.

DStop testing after the first try.

Solution & Explanation:Moving the magnet farther (or adding a spacer) reduces force. Retesting finds the sweet spot where it still holds >= 8 shakes and opens more easily.

Problem 2Difficulty: Mastery

Which design best fits?

AEmbed a magnet in the lid rim and attach a thin metal ring on the jar's outside rim so the magnet pulls from the edge.

BPut a magnet inside the jar with the samples.

CGlue the lid shut.

DUse a metal nail through the lid.

Solution & Explanation:Placing the magnet at the rim keeps it away from samples, and a metal ring outside provides a target. It holds during shaking and is still removable.

Problem 3Difficulty: Mastery

Which is the best design choice?

AUse a very strong magnet on the outside of the journal.

BUse two strong magnets on the outside corners.

CAdd more metal to the outside so it sticks less.

DUse small magnets hidden inside the cover and keep them just strong enough to latch; test near other metal items.

Solution & Explanation:Small hidden magnets reduce the magnetic field outside the journal and lower unwanted sticking, while testing ensures the latch still holds shut.
