Brighten Up Learning with Light-Up Nonfiction! This simply written, colorfully illustrated book introduces young astronomers to the planets, moons, and other outer-space objects that make up our solar system. Fun facts encourage readers to get to know their place in space. Hands-on activities and an interview with a NASA scientist add to the learning. Plus, just for fun, this book features an attached light-up sun, the "star" of our solar system. Kids can press it once to turn it on and press it again to switch it off.
