This 8-page printable book (4 page pdf file) introduces elementary students to the solid state of matter. It discusses the three states of matter, properties of matter, classification of matter, and the properties of solids. The book includes pictures and comprehension questions designed to test recall and basic comprehension skills. The Flesch-Kincaid reading level is 2.7, and I have used this successfully with second grade students in a study of states and changes of matter.
