Why Lesson Planet?
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data comparing gestation time to number of babies born and lifestyles to find that gestation is an environment-influenced adaptation. Plenty of critical thinking is stimulated through these activities, and as a result, your class will more fully understand gentetic variation.
