Young learners have a lot of questions about light! Natural light from the sun illuminates our days and keeps us warm while manmade lights keep our homes bright at night. But those aren't the only things that light creates! In this introduction to light, readers will learn about light from Snappy the Nile crocodile. Find out how light creates shadows or how we need light for mirrors to work. With questions asked by Snappy, readers are encouraged to discover on their own.
