These cards are the Science Essential Questions for the
Houghton Mifflin Harcourt's "Florida Science Fusion" - 1st Grade text.
See the text book cover above to make sure this is the right set for you.
I have made these cards to be cut down to 4x6 size so that they don't take up all your valuable board space and so they can be easily stored in an index card box. Simply print, laminate if you would like, and cut out.
Each of the 8 units has a different background and the lesson numbers are clearly labeled to make finding the right card easy.
