The Best STEM Activities for ST. Patrick’s Day

If your kids love ST. Patrick’s Day, they will have a blast with these St. Patrick’s Day science and St. Patrick’s Day engineering activities. Learning has never been so fun!

What is a STEM Activity?

A STEM activity (sometimes called STEAM activities, too, if there is an art element) are activities for kids that include elements of Science, Technology, Engineering, and Math. These four elements are the cornerstone of modern careers and scientific advancements.

Children can benefit from completing STEM activities not just because it helps them learn more in the STEM subjects, but also because it helps them see how these subjects are used in the real world.

As a side benefit, STEM activities help children learn to think creatively, logically, and critically about everything they do and see.


Kids can learn a lot with St. Patrick’s Day STEM activities. Young children can learn topics including:

  • Cause and effect
  • Volume
  • Reactions
  • Color mixing
  • Weight
  • Patterns
  • Counting
  • Sorting and classifying
  • Scientific terms
  • Math terms
  • Physics
  • Spatial awareness
  • The scientific method

The goal of STEM activities at the preschool and toddler level is to explore the world and learn the basics of the scientific method, the creative process, and how to tie all elements of science, technology, engineering, and math together. Sensory bins are the first path toward establishing a love of STEM topics that will last a lifetime.

In addition to establishing a love of science and exploration, St. Patrick’s Day STEM activities help children explore the world creatively and inspires them to ask the big questions that will one day change our world.

What Can Kids Learn with St. Paddy’s Day STEM Activities?

St. Patrick’s Day is traditionally a holiday about rainbows and magic coins, but, you can definitely tie in the STEM elements of Science, Technology, Engineering, and Math into your St. Patrick’s Day fun! Learn about the science of rainbows, or engineer your own leprechaun trap!

There are tons of fun ways to learn and play using STEM thinking skills that will help prepare children for a lifetime of critical thinking and logic with these fun St. Patrick’s Day STEAM activities!  

Kids are naturally curious, and science and STEM is all about answering those questions that so many preschoolers have about the world.

Through touch, exploration, and research, even the youngest kids can learn a lot about science and how the world works.

Kids who are introduced to science and STEM from the start are more likely to have a love for STEM topics as they continue their school careers and enter into careers as an adult.

If you don’t want the mess of bins, you can also make science discovery bottles for your class for quick science learning.

The Benefit of Seasonal STEM Activities

You probably agree that STEM activities are important to do even with the youngest kids. But you may not want to try seasonal STEM activities with your class. There are tons of creative STEM activities  that you can do, and you’ll probably never run out of STEM challenges. So why bother with seasonal STEM?

I like doing seasonal STEM activities with my kids because it adds an educational element to our holiday celebrations.

Rather than just doing a seasonal craft, we do a few STEM activities that match the current season or holiday. Seasonal-based activities also provide a way to engage kids who might be reluctant to do science or STEM challenges on their own.

Some kids might not want to do a big project like our energy-efficient-window-science-fair-project. but they’d be perfectly happy to build a leprechaun trap for St. Patrick’s Day!
