Title: Natural science through the seasons
Description: It was published by MacMillan in Canada, in 1946 and 1955, as a year-long teacher's resource. Each month has a variety of activities that might be suited to what's growing or hatching during that time (at least in Ontario). Each month has a sample day-by-day calendar with natural things to look for that you can build up "on your blackboard" (or on a regular calendar, for homeschoolers). Each unit has suggested activities, divided into those that are especially suitable for younger and older grades. There are experiments, questions, little verses to learn (or maybe to use for copywork), charts for identifying evergreens, and more things to draw on the blackboard.

And then each one also has a reading list, including suitable pages from Anna Comstock's Handbook of Nature Study; books such as Parker's Golden Treasury of Natural History and Dorothy Shuttlesworth's Exploring Nature with Your Child; and books by other authors whose books are still available: the D'Aulaires, Milicent Selsam, and Roger Tory Peterson.
