No Textbook Needed. Basics of Physical Changes, Chemical Changes, and Temperature in relation to Physical and Chemical Changes. 17 Pages. 5 work sheets with stories with 5 pages of answer sheets; 1 worksheet in table format with answer sheet; 1 study outline with answer sheet; and 2 pages of quiz with 1 page answer sheet. Stories in a play like reading so students may take part as characters when reading aloud. I use this for my 5th Grade science and they enjoy it very much.
