St. Patrick’s Day is such a fun holiday! No pressure to do anything big, which after Thanksgiving through Valentine’s Day is very nice. We don’t really do much of anything to celebrate, to be honest. I try to get the kids to wear green. Maybe I’ll make some green food. But really that is it. One easy way to theme out? STEM activities! There is no need to get crazy with it. Simple and quick activities can be a ton of fun and bring some holiday spirit into your day. Here are some fast and easy St. Patrick’s Day STEM for toddlers and preschoolers.
