The best resource that I have found for frog dissections is Net Frog by Mabel Kinzie has a fabulous interactive virtual frog dissection including many multimedia resources such as videos and narration for every step of the dissection. It is an excellent resource for teachers, for students to preview or review the material, and as an alternative to an actual frog dissection.

In addition to Net Frog, other good lesson plans include:
Structure and Function in Living Systems
5. The anatomy and physiology of plants and animals illustrate the complementary nature of structure and function. As a basis for understanding this concept:
a. Students know plants and animals have levels of organization for structure and function, including cells, tissues, organs, organ systems, and the whole organism.
b. Students know organ systems function because of the contributions of individual organs, tissues, and cells. The failure of any part can affect the entire system.
c. Students know how bones and muscles work together to provide a structural framework for movement.
d. Students know how the reproductive organs of the human female and male generate eggs and sperm and how sexual activity may lead to fertilization and pregnancy.
Physical Principles in Living Systems (Physical Sciences)
6. Physical principles underlie biological structures and functions. As a basis for understanding this concept:
j. Students know that contractions of the heart generate blood pressure and that heart valves prevent backflow of blood in the circulatory system.
Grades 9-12 Biology
9. As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic) despite changes in the outside environment. As a basis for understanding this concept:
a. Students know how the complementary activity of major body systems provides cells with oxygen and nutrients and removes toxic waste products such as carbon dioxide.
b. Students know how the nervous system mediates communication between different parts of the body and the body's interactions with the environment.
f. * Students know the individual functions and sites of secretion of digestive enzymes (amylases, proteases, nucleases, lipases), stomach acid, and bile salts.
g. * Students know the homeostatic role of the kidneys in the removal of nitrogenous wastes and the role of the liver in blood detoxification and glucose balance.
