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.
