In this lesson students were learning about genes, inheritance and blood types. The introduction to the lesson addressed how genes get passed down from parents to their offspring. Students learned that one of the ways scientist keep track of the genes that could be past down to their offspring is by using the Punnett Square. Through an explanation of the Punnett Square we talked about the difference between genotypes and phenotypes. Once we were comfortable with the topic we went on to the activity.
In the activity, students where given synthetic blood and anti-bodies to see which antibodies reacted with their blood. Then, they were encouraged to trace back the genotype of their parents knowing the type of blood the offspring had.
