Grades 6-8
Simply Grammar
A very simple and lovely grammar book based on the text First Grammar Lessons written by Charlotte Mason in 1928. The text is illustrated with charming 19th century drawings which are used within the text for exercises such as: completing sentences and making sentences of certain types and telling stories using certain parts of speech. The text is intended for fourth grade and up (the Charlotte Mason method recommends waiting until then for formal grammar studies - focusing on reading and narration earlier).
Eyewitness: Astronomy
Although most books in the DK Eyewitness series are at least slightly problematic in the text, our family enjoys a number of them entirely for the sake of the pictures. Eyewitness: Astronomy is one of the ones I wouldn't bother with even for the pictures. Although there are many beautiful photos, the book overall is both disappointing and even problematic in places.
Space Encyclopedia
We've started working our way through parts of this book as a read-aloud for younger children but have enjoyed it especially for the pictures. It covers everything from the Hubble Space Telescope to the surface and atmosphere of the Sun, Moon and Planets, from Space Pioneers to star maps, from explanations of various types of telescopes to black holes and discussions of the possibility of extraterrestrial life. We've only read a small portion of the text so far, but were pleased to find that the text came out better than expected in several litmus-test areas.
Astronomy for Every Kid
Offering "Exciting ideas, project, and activities for schools, science fairs, and just plain fun," this book is one in a series that is very popular with homeschoolers (and understandably so). The book covers seven major topics - Planets, Space Movement, The Sun, The Moon, The Stars, Space Instruments and Space/Space Travel. Each experiment uses simple experiments and explains (briefly) the purpose, the procedure, the expected result and a brief but very understandable explanation of why it happened. Black and white sketches illustrate each experiment as well.
