This is a science challenge for student and adults. It strengthens their science vocabulary, and increases an awareness in the environment. Also, by decoding or deciphering the words increases their perception. The staff can have a bit of fun with this, too. Perhaps, a small inexpensive flowering plant can be given to the teacher/ student who solves this puzzle first! An answer key is provided. Thanks ever so much for visiting.
