Science Activities with Preschoolers

Science is a magical thing. It is best enjoyed when it is child-led and hands-on, which is pretty essential when working with preschoolers! Preschoolers love to be involved, even in the simplest ways. Incorporating science activities from a young age helps children learn that failure is part of the process and it’s perfectly ok. When you do get it right, especially after many tries, it is all the more incredible! We sure hope these preschool science activities help your preschoolers learn to love science and all the magic that lies within.

Beautiful spring days call out for bubbles, but no need to stock up on bottles of the stuff — just make your own, including the wand! This sweet ‘big guy’ shows you how.

How to Make Oobleck | Crafts for Kids | PBS KIDS for Parents

Making oobleck is a great science and sensory project combined into one. After combining cornstarch and water, dip your hands into this non-Newtonian fluid, fluid that acts like a solid and a liquid at the same time.

Making and using Oobleck is a great outside or in the kitchen activity. It is our favorite version of "clean mud". For more fun, add pretend bugs or other small toys to use in the "mud". This activity cleans up very easily.

Children learn about the properties of a solid and a liquid. Because it acts like a solid when it is still. However, when you touch and grab it, it acts like a liquid.

In addition, it is a great calming activity for children.
