Inquiry in Action—Investigating Matter Through Inquiry, Third Edition is a free printable resource from the American Chemical Society. The activities in the book are also available separately on the Inquiry in Action website. Designed for grades 3-8 it is something we will likely use when we get around to chemistry as an official subject. (Right now chemistry is something we do for fun!) It addresses the following topics:
● Scientific questions and their investigationAlthough not free, the American Chemical Society also published a couple of science books that look good for the preschool through second grade set. I just ordered both of them (used, through Amazon, and for cheaper than the links that follow), titled
● Physical properties
● Physical change
● Dissolving solids, liquids, and gases
● Chemical change
● States of matter
Since we're just starting to work on writing letters with my 4-year-old I thought the first title would correspond nicely. It seems perfect for a letter-of-the-week type curriculum! I'll let you know how we like them once we've had a chance to use them.
