WHAT DO KIDS LEARN DOING SCIENCE EXPERIMENTS FOR ST. PATRICK’S DAY?
Kids can learn a lot with St. Patrick’s Day science experiments. Young children can learn topics including:
- Cause and effect
- Volume
- Reactions
- Color mixing
- Weight
- Patterns
- Scientific terms
- Physics
- The scientific method
The goal of science experiments during elementary school is to explore the world and learn the basics of the scientific method, the creative process, and how to tie all elements of science together.

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

WHY DO ST. PATRICK’S DAY SCIENCE EXPERIMENTS?
St. Patrick’s Day is traditionally a holiday about rainbows and magic coins, but, you can definitely tie a bit of science into your St. Patrick’s Day fun!

Kids are naturally curious, and science and elementary science is all about answering the questions that children 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 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.

WHAT ARE THE BENEFITS OF SEASONAL SCIENCE PROJECTS?

You probably agree that science projects are important to do even with the youngest kids. But you may not want to try seasonal science experiments with your class. There are tons of classic science experiments that you can do, and you’ll probably never run out of STEM challenges.
So why bother with seasonal science experiments?
I like doing seasonal science experiments with my kids because it adds an educational element to our holiday celebrations.
Rather than just doing a seasonal craft, we do a few science projects that match the current season or holiday.
Seasonal-based activities also provide a way to engage kids who might be reluctant to do science challenges on their own. Some kids might not want to design an energy efficient house, but they’d be perfectly happy to build a leprechaun trap for St. Patrick’s Day!
