Throughout the semester, Mr.Bradley's Advanced Biology class has had the opportunity to dissect different animals as students begin to learn about the evolution of the kingdom Animalia. Dissection allows students to compare the evolutionary changes from the earliest developed animals to the latest. Students learn about the differences in bone structure, heart, habitat, diet, and many other things. Dissecting is an easy way to see these differences, and put them into perspective.The students have dissected a turtle, a frog, and a crayfish, and plan on dissecting a few others. The class dissects different animals about every two weeks, depending on the classes progress.
|Michael and Dustin focus on details during dissection.|
In the most recent dissection of the turtle, students were able to see how protective the shell of a turtle is, the difference in the lung of the turtle and humans, the sharp claws of this creatures, the beak they use, and many other distinguishing characteristics. It is hard for many people to visualize all of the anatomy that goes into each class of animals, so this is an easy way for the students to see the body structures. Many differences we see among the diversity of animals is their differences in hands or claws, lungs, teeth, and digestive systems. In addition the view of the inside of these animals is awesome.
Mr. Bradley is the one teacher in the high school that uses animals to dissect. The anatomy and physiology class also gets the opportunity to dissect a baby pig. They study the human body, and the pigs allow them to see certain things about the anatomy of the pig.
