10+ Amazing Science Activities for Preschoolers

{Psst…If you make it to the end of this post, I have a little surprise for you.}

What is Science in a Montessori Setting?

Science permeates many areas of a Montessori classroom. Dr. Montessori viewed all children as little scientists, the world’s best and most curious explorers. Science, art, & math are often interwoven in a Montessori classroom. In other words, science is about the process, creating, and perspective.

What is a scientist?… We give the name scientist to the type of man who has felt experiment to be a means guiding him to search out the deep truth of life, to lift a veil from its fascinating secrets, and who, in this pursuit, has felt arising within him a love for the mysteries of nature, so passionate as to annihilate the thought of himself. ~ Dr. Maria Montessori

Science is not simply about doing an activity, it is about experimenting. Furthermore, doing a science project involves failing, iterating, observing, and making hypotheses. Science is not is about definitive conclusions.
