Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform.

What was your experience, both successes and challenges, using this lesson object with your students?

This one is a bit difficult because the quiz was computer graded, that leaves little interaction between student and teacher on the assessment piece. Is there initial confusion because of the similarity of the word homeostasis? The video differentiates the lesson for more visual and auditory learners.
