AT&T Classroom Podcast 7- Genetic Babies
Genetic Babies in the AT&T Classroom
Marlene Osborn's seventh grade class from Roberts Middle School spent six weeks investigating genetics. Flip booklets and other models using various forms of technology were crafted depicting the stages of mitosis. DNA was extracted and the materials were investigated using the Intel digital microscopes. Students examined many inherited traits like PTC tasting, widow’s peak, hitchhikers thumb, free ear lobes etc. and built heredity wheels using Paint Shop Pro to enter the data. The culmination of the unit was a simulation of a gene pool where students randomly selected gametes with their inherited traits for egg and sperm. These combinations resulted in genotypes which were used to create “genetic babies”. Assessment of student understanding using the Turning Point personal response system provided the teacher with an alternate method of tracking student knowledge.
