& Ethics
Students realize that science, including genetics, is part of their
everyday lives. Hence, the ‘Everyday Scientist’ theme/narrative.

10. Possible Class Conclusions
Genes are causing different physical traits
Different band patterns = different DNA
Larger uncut DNA samples = genes inserted
Smaller uncut DNA samples = genes deleted

11. Ethics, Society & Science:
GMO Research Project
• Literature research
• Group presentation
Design GMO to • Peer evaluation
address a • Rubric-based assessment

• Individual work
• Argue both sides
