Looking for a St. Patrick’s Day STEM Challenge that your students will love but is more than just a craft or activity to pass the time?

The basic premise:

Working against criteria & constraints individually or in partners/groups, students will design and 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.

Modifications included for grades 2-8.


Note: This version is for use with Google Slides in 1:1/paperless classrooms. If you prefer to print and have students complete work with paper/pencil, you'll want to look at the PRINTABLE VERSION instead.

If you have questions about which version is right for you, please feel free to leave me a question using the product Q&A below.

Benefits of this STEM Design Challenge:

- 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 ~60-90 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.
