For Pi Day (3.14), the San Antonio Botanical Garden celebrates the significance of circles!
From 9 a.m. to 1 p.m., guests can enjoy:
- Slice of Pi(e) in the Outdoor Teaching Kitchen
- Tree Ring Discovery: Count rings and calculate a tree’s age
- Tree ring print station: Create your own take-home print
- Compare the Rings: Explore how tree species grow differently
- Pi-Ku writing station: Craft a poem inspired by 3.14
- Digits of π Challenge: How many can we write together?
- Pi scavenger hunt throughout the Garden
- Sound wave exploration inside the Lucile Halsell Conservatory
These activities highlight how π connects measurement, nature, and even sound.
From 3:14 to 4:14 p.m., keep the celebration going at Mathy Hour. Sip Pi-inspired cocktails, share your Pi-Ku at our open mic, create a grass flower crown, make a bracelet, and enjoy relaxed social time surrounded by spring blooms.
Throughout the day, mathematicians from Trinity University, St. Mary’s University, and Southwestern University will be onsite with hands-on activities and casual conversations that reveal the wonder of math in the natural world. No math expertise needed; curiosity required.
Leading up to and following Pi Day, explore Pi-inspired circular garden designs blooming across the Garden at your own pace.
