Tree of Life Charts - You may view the files to use as a pattern to make your own charts. If you wish to have these charts printed, copy the files to a memory stick or CD to transport them to a printing business that has a wide-format color printer. Make sure the files are printed at 100% scale (full size). There are color and black & white photos that children can place on each of the colored rectangles. These photo cards are in the appendix of the book, Kingdoms of Life Connected. The photos are printed on card stock. They can be removed from the book and cut up for use on the charts. The text on the back of each photo tells where it belongs on the charts and has other information about the organism. You may also purchase the file to print a color photo card set for these charts. Look for the color photo of the wasp, one of the subjects pictured on the cards.
