We love John H. Tiner's science books for middle school students. He writes from a biblical perspective and has won numerous awards for his books on science and medicine for young people. They are excellent introductions to the people and places central to the planet earth, the history of medicine, chemistry, mathematics, and physics. These illustrated books have review questions and activities after every chapter, and Memoria Press has added additional supplemental review questions to each chapter, unit reviews, unit tests, and a final exam for each book in the series.
The series includes:
Exploring Planet Earth: The Journey of Discovery from Early Civilization to Future Exploration
Exploring the History of Medicine: From the Ancient Physicians of Pharaoh to Genetic Engineering
Exploring the World of Chemistry: From Ancient Metals to High-Speed Computers
Exploring the World of Mathematics: From Ancient Record Keeping to the Latest Advances in Computers
Exploring the World of Physics: From Simple Machines to Nuclear Energy
Exploring the World of Biology: From Mushrooms to Complex Lifeforms
