Classroom/Laboratory Activity: Climate Change and Leaf-out in Plants

A classroom/laboratory activity to explore the possible role of climate-related environmental factors in the timing of leaf-out in plants (specifically, red maple leaf-out in New England). 

In this activity, students will create graphs by using data for the timing of red maple leaf-out in New England. They will analyze these graphs and discuss the possible effect of changing spring temperatures on leaf-out.

Use this tool to help students find answers to:

  1. What is leaf-out?
  2. What are the climate-related factors that may affect leaf-out in plants?
  3. Which phenological events in plants could be affected by a change in the average spring temperature?
