Save this idea for later!

STEM (science, technology, engineering, and math) is a hot topic right now. As technology continues to advance, these subjects will continue to be important in school and beyond.

But you don’t have to wait until elementary school to begin STEM activities for kids.

Even toddlers can get in on the action with these simple STEM projects for toddlers.

Have a toddler? Start a love of science early with these STEM projects for toddlers! Little ones will love these creative and educational ideas!

At the toddler level, STEM activities for toddlers are all about exploring the world around the kids and learning the basics of math, spatial awareness, cause and effect, the scientific method, and how to have fun with learning!

Toddlers can use the skills learned during STEM activities and science experiments all throughout their school years, which will give them a big advantage over non-STEM-educated peers.

What are STEM Activities for Toddlers?

STEM projects for toddlers help children explore a variety of thinking skills that boost both their creativity, logic, spatial awareness, fine motor skills, and gross motor skills.

Toddlers who engage these systems, versus toddlers who largely learn from screens and immobile activities have a huge advantage once they reach school-age.

Today’s kids get less interaction with the world and their environment than kids in decades past, much to the detriment of their development.

A toddler STEM activity is simply a structured, yet open, activity for children to explore their natural curiosity while developing essential mental and physical skills that are essential to growth and learning.

What Do STEM Projects for Toddlers Involve?

A toddler STEM activity looks nothing like an elementary school STEM activity, but the principles remain the same.

Toddler STEM activities work by applying STEM thinking to everyday toddler activities.

A typical toddler STEM project might include elements of science, technology, engineering, and math in the following ways:

Science: Exploring cause and effect. Manipulating and combining objects to see what happens. Exploring textures, tastes, and smells.

Technology: Using basic tools like magnifying glasses, large screws, and glue to create something new.

Engineering: Exploring how objects work together and identifying the best material for a task (for example, finding out that blocks are better for stacking than stuffed animals).

Math: Counting, weighing, and measuring objects. Exploring basic properties of physics, motion, and gravity.
