For science in the elementary grades I like to use lots of animal and nature stories. Burgess Bird Book, Burgess Animal Book, Gregor Mendel: The Friar Who Grew Peas (first geneticist), Little Wanderers (how seeds travel), Secrets of the Woods, Pagoo (life of hermit crab and other sea life), Madam How and Lady Why, The Storybook of Science. Outdoor Secrets & Dooryard Stories for the younger ones. I pull heavily from the Ambleside Online lists.
For history we use An Island Story (British history from early Roman rule to beginning of 20th century), This Country of Ours (American), A Child’s History of the World by Hillyer (a family favorite) Landing of the Pilgrims by James Daugherty, Trial and Triumph: Stories from Church History, Abraham Lincoln’s World, George Washington’s World, Augustus Caesar’s World, (all 3 tell stories of important people around the world during the life of -Lincoln, Washington, or Caesar-).
Plus lots of great biographies. We enjoy the books by D’Aulaire like Benjamin Franklin, George Washington, Abraham Lincoln, Buffalo Bill, Pocahontas, Leif the Lucky. Some other good ones by Dianne Stanley are Joan of Arc, Michelangelo, Good Queen Bess, Bard of Avon: The Story of William Shakespeare. Some more biographies (yeah, we enjoy a good biography around here 🙂 ) Leonardo Da Vinci by Emily Hahn, Squanto by Feenie Ziner, Poor Richard by James Daugherty, Abigail Adams: Witness to a Revolution by Natalie S. Bober.
