Bee ready for a fun and buzz-worthy STEAM adventure on Saturday, April 18, at Glen Helen Regional Park, as we introduce the world of bees and why they are vital to our eco-system.
In this activity, each young scientist will create their very own bee and use it to “pollinate” colorful construction-paper flowers, bringing science, creativity, and problem-solving together in a playful way.
All ages are welcome! Admission is $15 per vehicle. Supplies are provided while they last.
Regional Parks are open daily from 7:30 a.m. to 6:30 p.m.
