Like humans, trees can become weak and unhealthy, suffer injury, and die. People have learned to read the symptoms of unhealthy trees to help them. In this activity, students will examine trees for signs of damage or poor health. They will also conduct a series of experiments to determine the conditions that may cause plants to become unhealthy.
This is one of 96 activities that can be found in PLT’s PreK-8 Environmental Education Activity Guide. To get the activity, attend a training either in person or online and receive PLT’s PreK-8 Guide. Below are some supporting resources for this activity.
Every month we carefully select new tools and resources that enhance PLT’s lessons. These include educational apps, videos, posters, interactive websites, careers information, and teacher-generated materials. Browse a chronological listing below:

In this short video from PBS Plum Landing, see how students work with a local arborist to plant a tree in their community. Underneath the video, you’ll find some simple conversation starting questions and additional resources to inspire your students.
STEM Teaching Tools
The University of Washington’s Institute of Science and Math created Practice Briefs. These free articles highlight ways of working on specific issues that come up during STEM teaching. These briefs helps K-12 educators and administrators stay informed on teaching STEM issues, including STEM issues relating to teaching NGSS and implementing meaningful STEM learning. Each brief is separated into digestible sections and includes recommended actions for educators.
Why Would Anyone Cut a Tree Down? – for Grades 1-3
In order to reduce tree hazards, protect other trees, or to get wood, it is sometimes necessary to cut trees. Why Would Anyone Cut a Tree Down?, a 41-page book published by the U.S. Forest Service, teaches students in grades 1–3 why it is important to sometimes remove trees from the environment.

The Hopeful Story of American Chestnut Recovery
This video blog post from Go Wood presents a clear summary of what happened to the American Chestnut (Castanea dentata), what is being done in the scientific realm to make a recovery of the species possible, and how you can help bring the American Chestnut back to the American forest. Go Wood seeks to educate people on the value of wood in society and is supported by professors at Penn State University Extension.
