It may sound awful to some people to cut open an animal and observe its different systems. But for budding biologists, it’s a real treat to get an opportunity like this. We had a series of dissections for 10th standard students recently to enhance some important concepts like reproduction in plants and human nervous system. Learning about the brain, its organization in skull, brain tissue and spinal cord is exciting to study and thrilling to watch live.
We started off with a dissection of a hibiscus flower so that girls could learn about the structure of the carpel (female part ), stamen (male part), placement of other whorls of flower like petals and calyx.
A little later, we began studying the nervous system, and dissected a goat brain, which was an amazing experience. Girls learnt about the location of the brain inside the cranium and various parts of brain like the cerebrum, cerebellum, medulla oblongata, and of course about the extension of the brain, the spinal cord.
There is a lot of difference between watching an animal dissection and doing it yourself, as girls found when they got to dissect open the brain of Scoliodon fish. But they utilized the entire fish very well by observing different systems in Scoliodon, like digestive system, reproductive system and heart.
It is such a joy to have been able to provide these experiences with the girls to support their learning. Their board examinations are just around the corner (in the beginning of March) and we hope that opportunities like this will help them understand the exam material even better.
