In this assignment we will watch The Biology of Skin Color video and answer questions related to the functions of the Integumentary system.
We will watch the video together during class time so that I can pause and explain some of the topics but I have also included the same video below in this assignment. All of the information needed to answer the questions correctly is found in the video but feel free to watch the class recording for additional clarification and discussion with classmates.
Here is a link to the class recording for this lesson- it includes an explanation for each of the following questions- I will update with this year's recording link after we go through this lesson together in class.
Here is a link to the class recording from 10/27/23
