Hey parents and caregivers! Looking for a fun way to get your little ones outside and engaged with the world around them? Why not mix some sunshine with science?
Outdoor STEM activities are a fantastic way to let your toddlers (ages 2-5) explore, learn, and burn off some energy. These activities are more than just fun—they’re little lessons in science, tech, engineering, and math.
One of the best outdoor activities with you toddler is allowing them to explore different areas and examine different trees, leaves, flowers, bugs, and rocks. With some supervision of course! As you are finding new things be sure to talk about what they are and how they interact with somethings your toddler is familiar with. This will help them build up their vocabulary and improve sorting and classifying.
You can also give them simple tasks like finding different colored leaves or flowers, counting trees in the backyard, or sorting rocks by shape.
You don’t need to bust out the books or calculators to practice some basic STEM skills outdoors. So grab your sun hats and let’s dive into the wonderful world of outdoor STEM for tots! 🌞🌿🔍
