Evolution and Adaptations
In common experience, the term "adapting" usually refers to changes during an organism's lifetime.
In contrast, evolutionary biologists use the term "adaptation" to refer to a heritable trait that increases fitness.
To help students reconcile these different concepts, this activity introduces the concept of phenotypic plasticity (the ability of an organism to adapt to different environments within its lifetime).
Questions guide students in analyzing how the balance between the advantages and disadvantages of a characteristic (e.g. an animal’s color) can vary in different circumstances, how phenotypic plasticity can be a heritable trait that can optimize fitness in a variable environment, and how natural selection can influence the amount of phenotypic plasticity in a population.
The Student Handout is available in the first two attached files and as a Google doc designed for use in online instruction and distance learning. The Teacher Notes, available in the last attached file, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.

Key for Evolution & Adaptation lesson
Hi,
Is there a key available for these lessons?
Thanks for the resources!
Answer Key
Unfortunately we do not have a key for this learning activity. If you make a key, I would be happy to review it and give you feedback.
We do have keys for many of the other activities on this website. For learning activities with a key, this is indicated in the Teacher Notes for those activities.

Love it
What a great job on the student and teacher sheets. I've been struggling trying to figure out a fun and interesting way to get kids involved with natural selection and evolution.
Video Link Broken
The Science Friday video link on cephalopod camouflage results in an error 404. Is there an alternative site to access the video?

Thanks for alerting me to this problem. This video is available at:
