Read this excerpt from a short story. For her science project, Rina had predicted that beans planted in potting soil would sprout first. To her surprise, the first sprouts to appear were planted in her mother’s compost mix.

"I told you, Rina," her mother said. "Never underestimate the power of coffee grounds and orange peels."
