How do ST. Patrick’s Day and STEAM Mix?
One of the things I never liked as a child is how alcohol-focused St. Patrick’s Day was. I felt left out as a kid.
Also, I really hated the tradition where you get pinched if you aren’t wearing green.
Once I tried claiming that I was wearing green underwear, but then the other kid asked to see it, so that was super embarrassing and I was lying anyway…
So yeah, St. Patrick’s Day and I didn’t have the best relationship growing up.
When my kids were old enough to start noticing the holiday, I wanted to do something fun with them that had nothing to do with food.
Since we love creative STEM activities, I thought it would be fun to create St. Patrick’s themed STEAM activities for my kids!
Each year, we do a few more projects and we’ve amassed quite the collection over the years! (you can see all of our ST. Patrick’s Day STEM activities here).
