Solve a Problem With Magnets

Aligned to 3-PS2-4 — Next Generation Science Standards.

What this lesson teaches

Because magnets can pull certain metals and stick together, you can use them to build helpful tools. A good design solves a real problem.

Worked example

A magnetic cabinet latch holds a door shut and keeps a curious puppy out, with no lock needed.

Practice questions

  1. List one everyday problem a magnet could help solve at your home.
  2. Draw a simple gadget that uses a magnet to fix that problem.
  3. Explain what the magnet must be able to pull for your design to work.
