Deer Antler Shedding

• How might the shedding of deer antlers help support their own survival, growth, behavior and/or reproduction?

• Do you think all deer have antlers?
• What do you think deer use their antlers for?
• Why might deer shed their antlers in the winter?

• Students could:
  • Use this as part of the engagement phase before beginning a unit about different organisms' structures and the functions of them. Students can begin to understand how these structures help the animal out in nature. They could be given the pictures of the antler sheddings and then asked to make predictions about why deer shed their antlers and what happens to them. Then they could use the resources listed below to understand and watch videos of the process. 
  • Create a claim about how deer lose their antlers and the importance of it. Identify and state evidence to support your claim.
  • Develop a claim on why some deer have larger antlers than others and what they use their antlers for. Identify and state evidence to support your claims. They can observe and reflect on different examples of deer using their antlers to fight each other for the female they want to mate. They can explain how this contributes to the antlers' function of growth, survival, and/or reproduction.
