This lesson was designed to follow the lesson Investigating Variation.
So having learned about types of variations, students are guided in this lesson to explore how inheritance works.
The lesson is set up as a problem solving activity where students are first presented with a problem on an inherited trait in a family where one member is the odd one out. In order for students to solve this problem they learn about Mendel and his work with pea plants where a similar problem is introduced. The lesson involves direct teaching of the concept of dominance and then guide students into developing models of crosses carried out by Mendel examining one of the seven traits.
Students are then guided into using this their knowledge and understanding of the basics of inheritance to solve the problem they were introduced to at the beginning.
Lesson include: Detailed lesson plan and student worksheets (14 pages) and PowerPoint presentation (17 slides) linked to the lesson plan.
To be able to determine the dominant and recessive alleles for a single trait (characteristic)
To be able to create models to predict results of a cross
To be able to communicate and present how inheritance wworks
