A Doorway of Amethyst
Here is a geology text that assumes no conflict between Christianity and science and is faithful to Church teaching. This book covers basic topics in geology, including the Earth's age and composition, the dynamics of continental plate motion, classification of rocks and soil, effects of glaciers, radiometric dating, and more. The illustrations are lovely and hand-drawn – not what you would expect in a textbook. However, I prefer a few glossy photographs as well, but you can find these on the internet.
Galileo's Leaning Tower Experiment
Science readers are to be found if you look around enough as this book demonstrates. It is the fictional story of Massimo, a boy who regularly throws his uncle's lunch off a bridge to his boat as his uncle rows by below. Galileo happens to see that the bread and the cheese land at the same time. The story ends atop the leaning Tower of Pisa, as legend suggests Galileo did.
