VOL: Make 100 Tree Cookies

mndeptnaturalresourcesHelp classroom teachers across Minnesota teach children how trees and other woody plants grow, factors that affect tree growth, tree identification, and more You can volunteer to create “tree cookies” which are slices of branches or trunks that show the rings of a tree 100 cookies are enough for about three classes of students, so the more you can make, the better They will be used!

How to Make Tree Cookies:

  • Slice the branches or trunk into half-inch thick, wafer-shaped “cookies” that are between three to six inches in diameter.
  • “Interesting” cookies with easily readable rings are preferred (these show a history of disease, disturbance, or other story.)
  • Dry the cookies correctly Do not skip this step or your cookies will rot See detailed instructions.
  • Sand the surfaces until the rings appear.
  • Finish the surfaces with clear varnish.
  • Optional – Label the cookie with the tree species and location cut.
  • Don’t use wood from ash trees.

This project can be done individually or with a group (scouts, 4-H, FFA, Kiwanis, etc.) You must provide your own tree or woody plant material, saws, sander, oven, varnish, and labor.

Project Learning Tree (PLT) program is a natural resources education program for teachers across Minnesota. Teachers often don’t have the time or capability to make these cookies so your help is greatly appreciated.
