How unique are you? What traits or characteristics make you uniquely YOU?
In this activity students will:
• Observe inheritable traits in themselves and their classmates.
• Observe that some traits are more common than others.
• Observe that it is a combination of traits that makes an individual unique.
• Organize and represent data collected showing the number of students that have specific traits.
• Identify patterns of inheritance – dominant and recessive.
This fun and engaging activity will introduce students students to the concepts of heredity, inheritance, trait, dominant, recessive, gene, allele, genotype, and phenotype.
Similar activities can be found on the internet and in some science textbooks. However, primary goals in this version are to apply mathematics skills and deepen and extend student thinking beyond the activity. In this lesson students observe easily visible or testable traits they have. Student compare their traits with other students in class and compile the frequency of traits in the population of students in the class. Students analyze data to identify a dominant/recessive pattern of inheritance. Students use resources to learn and apply appropriate vocabulary.
