Mark of a square bit of your yard - a place you can let go wild for a couple months while you watch it. Measure off a square that is anywhere from one foot to one yard on each side. Pound in a stake or stick at each corner and tie a string around them to mark your square. If you have bright cloth or tape, mark the tops of the stakes so they don’t get mowed.
Now look closely at your square. Write down everything you find. Draw some pictures. Show the colors of what you see.
Remember to take your sketchbook or journal with unlined pages, something to draw and write with, and something to add color ~ watercolors, colored pencils, crayons, or markers.
