Know: I knew that trees’ branches break when a heavy snowfall occurs in my backyard. I want to know why my previous observation occurred and what we can do to avoid it. I did online research from a variety of sources to find answers to the question I had.
Learned: I know that trees and plants have evolved for many years to withstand the conditions that they grow under. I know that global warming has had an impact on the climate which affects rainfall, hail, snowfall, and hurricanes, which, with enough force, can break, damage, and kill trees and plants. I know that understanding the biomechanics behind plants and trees is important to answer these questions.
New Questions: What was the evolutionary track trees and plants took to get to the point where they are today?
How have extreme weather conditions escalated over the past few years/decades?
