You Will Need:
A bag to collect leaves, Coffee filters, Heavy book, Journal or scrapbook, Marker, Double sided tape or glue. A tree identification book or internet site such as: http/mbgnet.mobot.org/pfg/diverse/temp/leaffind.htm Or www.worldbook.com
Go on a walk and collect many different types of leaves. Press each leaf between 2 coffee filters and place in a heavy book (a phone book works well). You may want to add more books on top. Let them dry for a few days. When through, place in your leaf journal or scrapbook and label with the type of tree it came from. Research the variety by using the book or internet.
Younger preschoolers may just sort leaves into categories such as round or pointed, brown or red, etc.
