SCIENCE EXPERIMENTS FOR PRESCHOOLERS WITH WATER

PRESCHOOL SCIENCE ACTIVITIES
Preschoolers are curious creatures and science experiments, even very simple experiments can fuel their curiosity. Learning how to observe, predict what might happen, and discuss what is happening are amazing tools for the future!
Science surrounds us, inside and out. Kids love checking things out with magnifying glasses, creating chemical reactions with kitchen ingredients, and of course exploring stored energy! Check out these 35 awesome preschool science experiments to get started.
There lots of easy science concepts that you can introduce kids to very early on, including water play! You might not even think about science when your toddler pushes a card down a ramp, plays in front of the mirror, laughs at your shadow puppets, or bounces balls over and over again. See where I am going with this list? What else can you add if you stop to think about it?
Science starts early, and you can be a part of that with setting up science at home with everyday materials. Or you can bring easy science to a group of kids! We find a ton of value in cheap science activities and experiments.
