Experiment and innovate with our new series of family activities: Science Saturdays! Stop by the fourth Saturday of every month for a new hands-on activity. Families work creatively together to solve a problem or make an improvement. Today’s activity invites visitors to explore and learn about the macroinvertebrates in our river through a leaf pack. Activities are included in regular admission and free for members. Use Hagley’s main entrance off Route 141 in Wilmington, Delaware.
