What is STEM in Kindergarten?

kindergarten valentine stem challenges

A STEM activity is similar to an expanded science experiment. STEM activities look for ways to bring science, technology, engineering, math (and sometimes art or design) into the science classroom.

Children need to learn how all of these subjects work together to make the field of “science” that is part of our world.

In kindergarten, STEM doesn’t focus as much on the technical side of science but instead provides a framework for intelligent and organized exploration of the world.

A kindergartener can learn to ask a question before starting a science investigation. They can learn about the tools that they can use to conduct the experiment.

They can learn about measuring and counting with a scientific lens. And they can learn that all science investigations should have order and follow procedure.

This is the goal of kindergarten STEM activities.

Additionally, kindergarten STEM activities (particularly during Valentine’s Day!) are all about exploring the world and having fun with science!
