I can’t get my kid out of the water so this is a great time to introduce a few quick water activities into our play. Kids can learn and play at the same time when you know how to choose the right preschool activities! Water is the key ingredient in all of these awesome water play ideas below. Easy preschool water activities you will love that include a bit of science.

SCIENCE EXPERIMENTS FOR PRESCHOOLERS WITH WATER

Quick water science experiments and activities kids will love. Preschool science, kindergarten science, and early elementary ages science activities using water and other common supplies. Free or nearly free science for kids is a budget friendly way to try science at home or in the classroom. We love simple science experiments and STEM activities and using water makes science extra fun and playful for kids

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.
