A Space of Learning and Discovery Preschool Wednesdays and Budding Scientists

Our Preschool Wednesdays offer toddlers and their families to go on a journey through story time, a live animal experience, and a maker space for crafts.

Budding Scientists is an immersive experience for kids ages 4-6 to learn basic scientific principles through hands-on activities and experiments.

These educational programs have been very popular and the education team is committed to improving the quality of depth and experience.  This year, there will be several modifications organized to enrich our preschool programs.
