Marcus kicked through the crisp October leaves behind Oakridge Elementary during afternoon recess. While searching for shiny acorns near the old boundary fence, a hollow knot in an ancient cedar tree caught his eye. Marcus peeked inside the shadowy opening. Wrapped in a faded red bandanna, a small carved wooden sparrow lay quietly concealed from plain sight. The carving bore smooth wings, tiny etched feathers, and the initials E.H. 1954 scratched into its base. A peculiar brass key was tied to the bird's foot with weathered twine.

Heavy spring thunderstorms had carved deep gullies through Willow Creek Nature Preserve, peeling back layers of mud. Ten-year-old Nina loved exploring exposed limestone ledges after big storms.

The Great Library Clock

Reading Passage Pay close attention to bold vocabulary words
In the quiet foyer of the Oak Grove Public Library stood a towering grandfather clock crafted in 1912. For three straight weeks, however, its brass pendulum halted at exactly 3:15 every Tuesday afternoon. The head librarian, Mr. Henderson, was completely perplexed by the mysterious stoppage. Fourth-grader Sam offered to investigate during his Tuesday study hour. Sitting on a stool, Sam observed the internal mechanism through the glass cabinet door. At precisely 3:14, a sharp beam of afternoon sunlight streamed through a stained-glass window, focusing heat onto a small brass balance spring.
