It’s a bright, cold February morning in Half Moon Bay. Sixth-graders are walking around the garden, collecting leaves of kale and chard, using their senses to scope out items for a scavenger hunt. Nearby, another group of students gather on a semicircle of hay bales to learn about milking goats, bolstering their voices to be heard over the contented clucking of the laying hens who wander the neighboring pasture. It is, for all intents and purposes, a typical morning at Vida Verde Nature Education.
