A Brain from a Can?! Observing a Chicken’s Brain!<\/strong><\/p>\n

\"\"<\/p>\n

“What, a brain from a can?!” When I first heard it, I couldn’t believe it. But when I actually opened the can, it was packed full of real chicken heads.<\/p>\n

In this article, I’ll introduce a “chicken brain observation” lesson conducted in a junior high school science class. I was invited to observe the class led by a teacher named Mr. Y. At first, the students were surprised, but they quickly became absorbed in the observation, their eyes sparkling with curiosity. There’s no educational material more impactful than a real specimen they can hold and examine with their own hands. In science class, topics like “the structure of the brain” and “the function of sensory organs” are covered, but hands-on observation with a real specimen provides students with a “three-dimensional understanding” that can’t be gained from a textbook alone.<\/p>\n

What is a “Chicken Head Can”?<\/span><\/strong><\/p>\n

The students used a can called “Chicken Head Can” for the observation. It’s mainly sold as dog food or reptile feed, and it surprisingly contains about 15 whole chicken heads.<\/p>\n

You won’t find these in a regular grocery store, but you can get them at pet shops or some online stores. When you carefully dissect and observe a chicken head from this can, you can see a part of the brain deep inside the eye sockets. While the entire brain isn’t large, the great thing about it is that you can clearly identify the structures of the cerebrum, cerebellum, and brainstem. This allows students to gain a tangible understanding of each part of the brain and its function.<\/span><\/p>\n

Let’s Take Out the Chicken Brain!<\/b><\/b><\/p>\n

When you open the can… it’s filled with a lot of liquid, so you’ll want to pour that out. Next,<\/span>gently take out the heads with chopsticks<\/b>and arrange them on a petri dish.<\/span>For each group, we prepared <\/span>two petri dishes<\/b>: one for the chicken heads and another for the brains after they’ve been removed.<\/span><\/p>\n

The smell is similar to canned tuna. It’s quite strong, but I didn’t think it was unpleasant. Now, let the dissection begin!<\/span><\/p>\n
