functions within multi cellular organisms.
HS-LS-1.3 : Plan and conduct an investigation to provide evidence that feedback mechanisms maintain
homeostasis

Group Work
• Task 1: Discuss AID (Artificial Insemination by Donor )method used to treat infertility
and describe ethical issues as well while choosing X or Y chromosome to be fertile.
Explain gamete Intrafallopian Transfer (GIFT)
• Task2: Summarize steps of IVF and address its benefits/drawbacks.
Explain Intracytoplasmic Sperm Injection (ICSI)
• Task 3: Compare IVF with that of AID and give your idea based on evidences that which
one is better.
• Task 4: Explain preimplantation Genetic diagnosis Who can benefit from PGD and
address ethical issues. ?

Move around
• Clock wise and explain your findings.
• Generate challenging questions on given cards while working in
groups/pairs.

• Exit Card:
• Challenge any one of the group with question you generated earlier
to answer all Q/A should be recorded in note books.
