Simple Preschool Science Experiments
Preschoolers are naturally curious about the world around them and fascinated by what they see and feel. Kids ages 3-5 love to ask WHY. This makes science activities one of the best ways to play and learn.
While preschool science lesson plans and preschool science curriculum is loose and play-based, the things that kids can learn are concrete and foundational. Preschoolers can easily learn the steps of the scientific method as part of science conversation. They will love making hypotheses and then using the tools around them to see if they were right.

Preschool Science Curriculum
When deciding what type of science activities and simple science experiments to bring into preschool at home or in the classroom, consider the following guidelines for preschool science standards:
- Physical Science – kids learn that objects have properties and there is a cause-effect relationship.
- Life Science – living things have basic needs and develop in predictable patterns.
- Earth Science – events such as night, day, weather and seasons have patterns.
