Give guidance and feedback to students' plans, encouraging, refining, and helping them to be responsible for their own learning. Maintain high expectations for completion of chosen options. Summarize by reviewing the whole, bringing students "full circle" to the experience with which the learning began.
Students explore genetic engineering, cloning, amniocentesis.
Objective: To begin to have students explore some of the current research being done which requires the understanding of the molecule called DNA.
Activity: Students do some out of class research on topics such as amniocentesis, cloning genetic engineering and genetic counseling. A possibility for this last section which serves as a very good lead in to a next chapter on DNA research today is to have a guest speaker come in who is a technician with an expertise in karyotyping. The guest could explain the purpose and procedure and show some real examples.
