When a family spends a day at the beach, the children investigate various footprints to see what type of creatures live along the shoreline. Rhyming text turns a sandy beach into an outdoor classroom. The tracks and habits of local wildlife, including hopping sandpipers, scuttling crabs, and burrowing turtles, are identified and explained for young ecology detectives. Even Daddy's feet make an appearance! And at day's end, it's time for tired feet to make their way home. STEM-based back matter includes information on how clues like footprints can identify the type of wildlife inhabiting any given habitat.
