Leprechaun Lockdown STEM Challenge

Leprechaun Lockdown STEM Challenge


This is a classic St. Patrick’s Day STEM Challenge with a twist. Perfect for those looking for St. Patrick’s Day activities that are brain-busting work disguised as fun!

Looking for St. Patrick’s Day activities that your students will love but are more than just a craft or activity to pass the time? This St. Patrick’s STEM Challenge (or STEAM Challenge) will keep your students engaged in brain-busting work disguised as fun!

The basic premise: 

You may know that leprechauns have the ability to grant three wishes to human captors in exchange for their freedom, but capturing leprechauns is trickier than it sounds!

Working in groups against criteria & constraints and equipped with a Leprechaun Lore List, students will design and build a device to lure and safely capture a leprechaun.


Note: If you are in a 1:1 classroom, you may prefer the
digital format, compatible with Google Slides ™.

Benefits of this STEM Design Challenge:

  • Focus on critical thinking, problem solving, and application of learning
  • Helps students develop growth mindset traits like persistence and resilience
  • High levels of student engagement
  • The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)
  • Highly flexible and differentiated for materials, timing, grade levels, and rigor.

Each design iteration should be planned for ~60 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly.
