How to Make a Leprechaun Trap
Follow along with these directions and make a plan to catch your very own leprechaun! What elements of STEM will you use to design your trap?
What Kids Learn Making Easy Leprechaun Traps

With the leprechaun trap STEM activity, kids use several STEM elements. Children must engineer a trap that will work to catch their imaginary leprechaun.
They must use elements of physics to make sure their design is stable and will actually trap the live leprechaun. They will use math to determine the angles and structure of the box design.

SETTING UP THE LEPRECHAUN TRAP STEM ACTIVITY
Before starting this activity, decide what limits you want to place on the activity. Maybe your challenge includes having a drop of some kind, so the leprechaun can fall in. Maybe you want the kids to make their traps using only craft sticks.
Or, leave the project completely open-ended! Gather your supplies together before starting.
Before letting the kids start the activity, go over the STEM elements. In my experience, once the kids start building their projects they don’t listen as well, so it’s better to let them have the background knowledge before they get started!
Use the STEM challenge worksheet to keep them on-track while making their traps.
LEPRECHAUN TRAP STEM QUESTIONS TO ASK

How does the leprechaun’s size influence how big the trap needs to be?
Can you name 3 ways to design a trap?
How strong does the trap have to be?
What could make your trap better next time?
DOING THE LEPRECHAUN TRAP STEM ACTIVITY

Our version is a classic rabbit trap. The kids made a box with a loose stick that was designed to fall easily. When the leprechaun entered the box to gather the treats, the kids pulled the string and trapped it.
Of course, the kids knew the leprechaun wasn’t real, but it was fun to test with each other! Test each student’s design and let the other kids vote on the best design.
