Procedure

Procedure I

1. Make a list of the instruments in the dissection kit. Place a sticker with the names of the members of the group on the lid of the dissecting tray and on the tray.




2. One student from the group should go to the table where the specimens were distributed.




3. A pamphlet of the dissection of the organism will be handed out. You must use this pamphlet but you cannot remove it from the classroom. This pamphlet serves as a guide for dissection of the body.




4. Since you enter the classroom you will be evaluated as part of the grade of execution of this project.

Procedure II

1. According to the organism that is assigned to you, you should start looking for the complete classification of each animal. (This part will require the use of reference books or the internet).




2. Once you know what your animal will perform the dissection on, follow these steps:
   
   

• Find the anterior and posterior parts of the organism, draw a picture of the organism and point them out. Please inform the teacher your thoughts to make sure that the parts are correct.




• Find the dorsal and ventral parts of the organism.




• Find the appendages.




• Indicate the parts of the organism (Head, thorax, etc.).




• Indicate the symmetry of the organism using lines that represent the planes and the symmetry of the organism.



• Once you complete this part, you may start the dissection.

Procedure III

1. Dissection: To begin your dissection, position your organism in anatomical position facing you. In other words, the ventral part of the organism must be facing upwards and the dorsal part against the tray.



2. Once you have your organism in this postion you should make the use of dissecting needles to keep the organism on the tray.
