"Blink, blink. What's that? A firefly! Such a tiny insect, but its light seems so bright in the darkness. Light is something we take for granted -- especially in the age of electricity. Where does light come from? How does it work? What is it made of? This lyrical picture book answers all of these questions, taking young children on a journey of scientific discovery and offering a charming and gentle introduction to light and all its mysteries. Kids will learn: how light is an energy that we can see; how all life on our planet depends on light from the Sun; how light helps us to communicate with others; how light waves travel in a straight lines and how they absorb, reflect and refract; how some animals can see at night; how we often use light to celebrate!"-- Provided by publisher.
