Cow eye dissection is popular because a cow's eye is similar to the human eye!

Using a scalpel, middle school and high school students can explore these preserved cow eyes to explore the amazing ways in which a cow's eye works (and thus, how a human's eye works as well)! Examine the different parts of the eye, such as the cornea at the front of the eye, the iris, the pupil, the sclera, the vitreous humor, the part where the optic nerve connects at the back of the eye, other connecting muscles and veins, and more! Learning about the various eye functions and parts of a cow's eye - by studying both the inside and outside of the eye - will give students a memorable, hands-on life science experience.

Include a cow's eye dissection in this year's lesson plan and give curious learners the opportunity to discover how an eye works with their very own eyes. We even provide a cow eye dissection kit that comes with a preserved cow eye, a full-color photographic dissection guide, a #22 broad-blade scalpel, scissors, and a sturdy disposable dissecting tray. Hoping to do a cow eye dissection with a number of students? Our classroom cow eye dissection kit comes with 10 preserved cow eyes, 10 illustrated dissection guides, 10 #22 scalpels, 10 scissors, and 10 dissecting trays. The economy classroom cow eye dissection pack is great for smaller classrooms or for students to share.

This is a plain preserved specimen of a single adult cow eye. 10+ pricing is based on bulk-packed specimens. When necessary, you will receive a combination of 10-packs and individually packed specimens to fill your order.

Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.

HST Specimen Guarantee

In sealed, original packaging, our preserved specimens are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.

Once the original package is opened, use specimen within one month. For best results, observe the following storage procedures:

  • Store specimen in heavy-duty, zip-lock bags to minimize drying between dissections.
  • Specimen will slowly dry out or become contaminated in zip-lock bags; add a teaspoon of Specimen Holding Fluid to retain moisture.
  • Freezing or refrigeration is not necessary and may damage fragile tissues.

Store your specimens at normal room temperature—refrigeration is not required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, specimens can be resealed in a zip-lock bag to prevent them from drying out for later use.

WarningWARNING: This product can expose you to chemicals including Formaldehyde, which is known to the State of California to cause cancer, and Methanol, which is known to the State of California to cause birth defects or other reproductive harm.
