If you have been following my recent posts, merging the physical and life sciences is a passion of mine. Currently we are studying optics in my introductory physics class. Using preserved cow eyes left over from a biology dissection last semester, I challenged students to remove the lens from the eye, and using, determine the focal length of the lens experimentally. Below is are videos of initial student exploration once the lenses have been removed.
I am teaching physics for the first time in 21 years! Beginning with a unit on conservation of energy by challenging students to create marble roller coasters using cardboard boxes and foam pipe insulator. The entire activity is based on this blog post by physics educator Ben Wildeboer. Click here for our class handbook with activity specifics and follow up inquiry cycle applications. See a few images below.
