Excerpt from The Biology of Horticulture (HORT 301) interactive video lesson focused on calculating Degree Days.
In the derived temperature indices interactive video lesson Dr. Ryan Contreras provides instruction on how to calculate three temperature indices related to plant growth. Each formula for Degree Days, Growing Degree Days, and Weighted Chill Units has its unique lesson. In each section students are introduced to the formula in question and provided interactive practice session to test their mastery of the formula.
The individual temperature indices lessons can stand alone, but are combined into the complete interactive video lesson. Total play though length of the lesson is approximately 20 minutes.
