Preschoolers are naturally curious, yet abstract concepts like magnetic fields can be elusive. By turning learning into hands‑on play, you can make magnetism tangible, safe, and memorable.
Collect everyday magnets: fridge magnets, horseshoe magnets, and commercial neodymium magnets. If you’d like to show a more powerful example, you can request a medical‑grade magnet, such as a Vagus Nerve Stimulator, from your local Epilepsy Foundation office.
Prepare a selection of items that will respond to magnetism (e.g., iron nails, stainless‑steel paper clips) and others that won’t (e.g., plastic blocks, wood sticks). Let the children choose a few to keep them engaged.
Set up a plastic or wooden table, place the magnets and objects on it, and let the kids experiment. When two opposite poles meet, they attract; like poles repel. Explain that every magnet has a north (positive) and a south (negative) side.
Ask the children to separate the objects into two piles: magnetic and non‑magnetic. Discuss why the magnetic pile reacts to the magnets—most are made of iron, nickel, or cobalt.
Place a magnetic object on the table, then slide different magnets underneath. Observe which magnets pull the object up or keep it in place. Talk about how some magnets are stronger than others.
Safety reminder: keep small magnets out of reach of young children to prevent accidental ingestion.
