If you’re tired of leprechaun traps already, Snake Snatcher is the perfect St. Patrick’s Day STEM Challenge for you!

In this challenge, students build a device to rid Ireland of snakes as quickly and safely as possible.

– Snakes (10 – 20) will be spread over a map of Ireland (three map options are provided). Student devices must lift snakes from Ireland and drop them in the surrounding ocean.

It’s a perfect introduction to legends, camouflage and mimicry. You can even incorporate integers with snakes and fakes, if that’s part of your standards!
