Equipment and Materials:Humpback whale puzzleHumpback whale gridWhale-size comparison chart Crayons and markersYardstickTransparent Tape8-9ft. X 12ft. (108 sq. ft.) heavy weight plastic drop-clothsPreparation:You will need a copy of the Humpback whale puzzle and Humpback whale grid for each student.  You will need a space at least 48 ft. X 18 ft. for the full-size drawing. An outdoor area is best.  Procedure:Introduce the project to your students by reviewing the body parts of the whale, the Humpback whale puzzle and the Humpback whale grid, previously completed inprior lessons.  Refer to Marine Life: Whales and Anatomy of a Humpback in thisbook.  Recommended Strategies:Tape together eight drop-cloths to form a rectangle measuring 18 ft. wide by48 ft. long.  Mark off and draw squares totaling l0 squares in length and 5 squares in width.  Assign one square of the Humpback whale puzzle picture to each student.  Have the students find the box on the large grid that matches the letter/number coordinate key of their piece.  Instruct the students to reproduce their small part of the whale into the appropriate box.  It will be important for you to monitor the boxes that form the outline of the whale.  Lines that start in one box and extend to the next must meet.  For maximum effect, place your entire class inside the whale!References:Museums:John G. Shedd AquariumField Museum of Natural History`
