The first Saturday of each month is Science Saturday at the Environmental Discovery Center at Spring Lake Regional Park in Santa Rosa. Families are welcome to stop by and join a Discovery Center naturalist for fun, hands-on activities with a different theme each month. This month we'll explore how climate change is impacting our local parks and landscapes. Our guest speaker will introduce the signs of a changing climate here in Sonoma County. Children will make a tree cookie craft and learn how trees tell the story of our climate. Programs begin on the hour at 1, 2 and 3pm. Science Saturdays feature tangible experiments and projects that let children explore the world around us.
