My preschoolers love to explore with magnets! Usually a surprise is involved when magnetic objects are attracted to our magnet wands, which is the best part. To add a new dimension, we mixed plastic eggs with our magnet wands, and came up with a fun way to figure out which kinds of objects are magnetic and which are not. The plastic egg magnetic science activity was a hit at home and at preschool! Plastic Egg Magnetic Science- magnet wand (or other larger magnet)- plastic eggs- objects for inside the eggs (both magnetic and not) For even more egg fun, try these activities too!
