Animal-Vertebrate Fish "Perch" Dissection<br />
(Adapted from: Prentice Hall <strong>Biology</strong> and various internet sites)<br />
NGSSS:<br />
SC.912.L.15.6 Discuss distinguishing characteristics of the domains and kingdoms of living<br />
organisms. (AA)<br />
Purpose of <strong>Lab</strong>/Activity: The purpose of the lab is to:<br />
1. Observe and identify the external parts of a fish.<br />
2. Dissect and identify the internal organs of fish.<br />
3. Observe and record the movement and breathing rate of goldfish.<br />
Prerequisites: Prior to this activity, the student should be able to know the names of anatomical<br />
structures from the vocabulary of the student section of this laboratory. The student should be<br />
familiar with the classification system of organisms.<br />
Materials:<br />
Preserved perch (fish)<br />
Dissecting tray<br />
Dissecting kit<br />
Dissecting microscope<br />
Paper towel<br />
Plastic bags<br />
Live goldfish<br />
Beaker<br />
Water from aquarium<br />
Fish net<br />
Stopwatch<br />

What the teacher will do:<br />
a. Acquire necessary materials and have stations ready for each group to<br />
survey or enough of each species in order for each group to survey all the<br />
species.<br />
b. Review the important parts or vocabulary with the students.<br />
c. Review safety procedures and guidelines, making sure that goggles,<br />
gloves, and aprons are being used.<br />
d. Group the students in productive teams. You can assign roles based on<br />
guidelines provided by the District. This would assist in classroom<br />
management and accountability.<br />
What the teacher will do:<br />
a. Provide guidance and support for questions on how to make initial incisions<br />
and dissection cuts. Move about the room and be available.<br />
What the teacher will do:<br />
a. Have a class discussion about the data collected and whether the<br />
hypotheses were proven or not.<br />
Discuss and review new questions that may have arisen about the evolutionary<br />
features of vertebrate fish.<br />
Extension:<br />
Repeat the experiment with a cartilaginous fish for comparison.<br />
Write a report on jawless fish or lobe-finned fish (coelacanth).<br />
