In the days leading up to our visit, please prepare your class by teaching them the anatomy and physiology of the following eleven eye structures:
Iris, Pupil, Cornea, Sclera, Lens, Vitreous Humor, Optic Nerve, Retina, Tapetum, Ciliary Body, Aqueous Humor
We have provided worksheets and other teaching materials for your class HERE if you would like to use them.
1. Prepare copies of Dissection_short_class.pdf (print double-sided, narrow margins), one for each student. The first page is the (labeled) ‘How to find your blind spot’ exercise handout. (We’ll instruct students how to take this handout home and use it to show their family members how to find their own blind spot.) The second page of the pdf informs caregivers about the dissection demonstration and provides them with prompts to help them ask the student about what was learned from the dissection. (For students who primarily speak, or whose parents primarily speak, Spanish, you can download a Spanish version of the same handout here: Dissection_shorter_class_Spanish version.pdf
2. We will bring our trays, dissecting equipment and gloves.
3. Arrange the lab tables to form 5 groups, and assign/organize four to six students to a group. Ensure there’s at least one student dissector in each group.
4. For each group, print 1 copy of the Cow Eye Dissection Placement Sheet for students to use during the lesson.
5. Be prepared to project a Powerpoint presentation (which you can download HERE) that contains five slides depicting the following content:
(Slide 1) Introductory title slide
(Slide 2) the ‘How to find your blind spot’ exercise
(Slide 3) a diagram of the eye
(Slide 4) a photomicrograph of a canine lens
(Slide 5) diagram of the Optic Chiasm
6. If you have one, place the 3D model of the eye on the demonstration bench. (We have only 1 complete model)
7. Have a generous supply of paper towels available to us and the students.
8. If a student objects to remaining in the classroom, send them with their Chromebook to view walkthroughs of the dissection in the following two videos: External Anatomy of Cow Eye and Internal Anatomy of Cow Eye. Make arrangements for that option with the receiving party ahead of time.
9. Designate a trash can for the eyeball waste and notify the custodian(s) of what to expect. Have extra trash can liners available.
