Safety Precautions
Scalpels, dissecting scissors, and needles are all sharp instruments; use caution when handling. Always cut away from yourself and others. Rotate the dissection pan, if necessary,
for better control while dissecting. Wear safety glasses, chemical-resistant gloves, and a chemical-resistant apron. Wash hands thoroughly with soap and water before leaving
the laboratory. Please follow all laboratory safety guidelines.

Procedure
Taking Dissection Labs Further
Dissection can be a fun and exciting lab exposure, but it also can be intimidating
and disorienting to cut into a specimen for the first time. Provide students with
a way to prepare and explore these organisms virtually with the Flinn Digital
Dissection™ Labs.
Comprehensive Digital Content
The digital platform off ers engaging text with clear, simple diagrams and video
tutorials that help students get the most out of their dissection experience. The
detailed background information on each species and questions to check for
understanding drive home important techniques and concepts. Built-in safety
guidelines and step-by-step instructions ensure that students have everything
they need to be successful and safe during lab. Meaningful end-of-unit
assessments round out the learning experience.
Interactive Exploration
Students benefit from hands-on interactive digital tools. Internal Organ
Explorations provide drag-and-drop diagrams of a microscopic view of a larger
organ or tissue and the opportunity to manipulate the organism’s internal
structures before tackling the real thing. Digitally picking up and moving around
anatomical features and organs helps students better connect the diagrams to the
actual specimen.
Help students prepare before
picking up a scalpel.
• Interactive digital content provides students with lab preparation,
hands-on manipulation, and reinforcement.
• Built-in safety guidelines and step-by-step instructions ensure that
students are safe and successful during lab.
• Serves as an excellent dissection enhancement or alternative.
Flexible Learning Options
Use these digital labs as a predissection assignment where students watch
videos and practice at home so they arrive in lab confident and ready to tackle
the science at hand. If students get stuck during lab or have trouble finding a
structure, the video tutorials are there to help. Use the digital content as extra
practice or as review for a test or even use the entire digital lab as a stand-alone
dissection alternative.

M1. The method of securing the frog to the dissection pan will depend upon the body position of the frog’s limbs.
If the limbs are extended forward, securely tie a twelve-inch piece of string to one foreleg. Thread the string
under the dissection pan and tie the free end to the other foreleg. The string should be taut, opening the chest
for easier dissection. Repeat with a second string around the hind legs. If the limbs are close to the body, use
dissection pins through the webbing of the digits of the forelegs and hind legs to secure the specimen.
M2. Caution: Always cut away from yourself and others. Rotate the dissection pan, if necessary, for better control
