Why dissection is good

Carolina obtains animals from many sources—some from cultures, some from natural or managed habitats where seasonal collections are made, and many from the food industry. Many animals and organisms are dead when we purchase them. For example, fishermen supply fish and sharks, and the fishing bait industry supplies earthworms. Animal shelters furnish euthanized cats that would be destined for the landfill were we unable to utilize them for science classrooms.

Abattoirs, producers of sausage, supply fetal pigs that would otherwise be considered offal and sent to the landfill. The current source for most preserved frogs for biology has an interesting history. Several decades ago, an area of desert was converted to farmland through irrigation. Man's changing of that land use also resulted in a large increase in the frog population in this area. One industry that emerged from this new resource is the provision of frog legs for food. As they progress, learners understand how science is studied and practised, and become aware that the results of scientific research can have both good and bad effects on individuals, communities and the environment.

By disecting a pig kidney, our Year 10 IGCSE Biology students could see that no two organs will look exactly alike, and this helps students understand natural variations, and recognise anatomy even if it does not look exactly like the textbook. It would seem that overly perfect alternatives cannot compete with the biological surprises of real specimens and the learning opportunities they provide.

From manipulating sharp instruments to employing delicate hand-eye co-ordination, the reality of physically dissecting a specimen can reinforce theory by including practical knowledge. Congratulations to our winners, but as always, each and every act showed what we already knew - students at BSN have talent!

We based our approach to UN day on one of the founding ideals of the UN, which is that nations must work together to overcome th The Go-Kart engineering S. From manipulating sharp instruments to employing delicate hand-eye co-ordination, the reality of physically dissecting a specimen can also develop fine motor skills. Indeed many a surgeon may well credit their career to the fascination afforded by a classroom session with the scalpel. Dissection is a memorable and instructive aspect of the biology curriculum, allowing students to learn how their own bodies work within the confines of the classroom.

Computer software and dissection models provide additional resources to reinforce this practical hands-on approach. Contact Edulab today for a wide range of dissection tools and kits to suit different skill levels and learning objectives.
