Reflection: Developing a Conceptual Understanding Apple Doesn't Fall Far From the Tree - A Tree of Genetic Traits - Section 3: Explore


One of the challenges of teaching science, in particular life science, is developing a conceptual understanding of a particular science concept.  In this lesson what I'm trying to teach is the concept of heredity.  In addition I'm trying to teach the concept of dominant and recessive traits and tackle the common misconception that dominant traits always have a higher frequency of occurrence. 

It is through hands on activities where students are able to visually see data that these conceptual understandings and misconceptions are addressed.  Students were able to see how certain traits are shared more in this particular student population due to heredity.  In not all cases was the dominant trait the one that had the highest occurrence rate.  Finally this activity led to valuable discussions not only in class but at home since majority of students attempted to complete this activity at home.  This activity fostered a sense of inquiry and genuine curiosity of how the world works, science at its best.
