Hi, my name is Olivia. I'm 6 years old, and sometimes I have questions about the world around us like: How do clouds make rain? Why is the sky blue? Why do the leaves turn different colors in the fall? Why do balls bounce? When that happens, I always go see my friend, Dr. Heidi. Dr. Heidi is a real scientist and probably the smartest person in the whole world. She always knows the answers to my questions. She also knows how to help me to really understand how things work. Today, Dr. Heidi and I are exploring something that's everywhere you look, but almost never notice, unless you're looking for it...that's right, but almost never notice, unless you're looking for it...that's right, light!Why not join us and have fun finding the answers to your questions about light and color by looking around corners with a mirror, creating new colors by combining primary colors, making a pencil break in half just by putting it into a glass of water, and lots of other cool science activities. "The Little Scientists Hands-On Activities" series of books is an outgrowth of the nationally acclaimed Little Scientists educational program. Like the popular scientific enrichment classes for which they are named, these books are designed to expose kids, ages 5 to 8, to the thrill of scientific discovery, while helping them to develop core scientific skills of observing, critical thinking, communication, classifying, comparing, applying and generalizing, measuring, predicting, hypothesizing, and problem solving.
