Reach for this book when your child starts noticing the dark shapes following them on the sidewalk or becomes fascinated by the way light leaks through the curtains. It is a perfect tool for transitioning a child's natural curiosity about the world into a structured, scientific understanding of cause and effect. By explaining how light travels and what happens when it is blocked, the book transforms a potentially spooky concept into an empowering physics lesson. Through clear photography and accessible text, the book explores how shadows change size and shape throughout the day. It encourages a sense of wonder and pride as children learn they can manipulate their environment using just a flashlight or the sun. It is an ideal choice for preschoolers and early elementary students who are beginning to ask why and how questions about the natural world, providing them with the vocabulary to describe their observations accurately.
None. The book is entirely secular and scientific in its approach, focusing on observable physical phenomena.
A 5 year old who is a budding observer of nature or a child who might be slightly nervous about the dark and could benefit from understanding that shadows are just blocked light. It is perfect for a child who enjoys 'doing' rather than just 'listening,' as it invites immediate physical interaction.

Sign in to write a reviewThis book can be read cold, but it is most effective if the parent has a flashlight handy to demonstrate the concepts on the wall as they read. A parent might see their child jumping on shadows, trying to 'run away' from their shadow, or asking why their shadow is so long in the evening but short at noon.
A 4 year old will delight in the visual changes and the 'magic' of the shapes. A 7 year old will begin to grasp the geometric relationships and the predictable movement of the sun, perhaps even using the book as a starting point for a science fair project.
Unlike many books that treat shadows as a spooky or whimsical device, Boothroyd focuses on the 'how' with high quality photography of real world examples, making the science feel tangible and achievable.
This is a foundational STEM concept book that explains the relationship between light sources, opaque objects, and the resulting shadows. It covers how light travels in straight lines, what happens when that light is blocked, and how the position of the light source (like the moving sun) changes the size and direction of a shadow.
