Age range 8 to 12When you think of holes, what comes to mind? Maybe the irritating hole in your sock. Or the hole on the shelf where you plucked out this book.A hole can be surprising, like a sinkhole appearing overnight. Holes can be useful, like the tiny openings in aeroplane windows, or dramatic, like a mine that's visible from space. They can even be lifesaving, like a seal's breathing hole in the ice.Holes are important to our everyday lives. They are investigated by scientists, used by artists, designed by engineers, and fixed by problem-solvers. They can be natural or human-made, big or small, plentiful or scarce, mysterious or very familiar. You'll find this book is chock full of holes — why not take a peek inside!Reading level varies from child to child, but we recommend this book for ages 8 to 12.
