Preschool Science Series
The love of science starts early.
Research shows that children grow socially, academically, and emotionally in play-based learning environments with caring adults. Our Preschool Science Series immerses early learners and their caregivers in playful learning and exploration through stories, experiments and hands-on activities. Designed especially for young scientists, we now offer two options for little ones and their caregivers to wonder, play, and discover together:

Preschool Science Series Is Changing Offering More Play, Wonder, and Learning All Summer Long!
Our Preschool Science Series will become an open exploration Learning Lab for Small Scientists on June 4! The new program is designed around research that shows children learn best through play, inquiry, and shared experiences with the adults who care for them.
From 9:30–11:30 AM, our preschool classroom will be open for small scientists ages 18 months to 5 years and their caregivers. Families are welcome to drop in, explore, and play at their own pace as space allows—stay for a little while or linger longer!
Inside the Learning Lab, you’ll discover:
- Hands-on experiments and playful STEM activities
- Opportunities to build motor, language, and thinking skills through doing
- Open-ended materials that invite tinkering, testing, and trying again
- Simple take-home ideas to help grown-ups keep the learning going
This flexible, joyful format lets children follow their interests, revisit favorite activities, and experience science as a playful adventure—together with you.
Come wonder, explore, and discover with us all summer long!
