How to write a formal lab report – Frog Dissection
DUE: ____________________
I. TITLE: Pick a descriptive title that is related to your investigation/research. Include the scientific name of the organism that you are dissecting. (Common name is Northern Leopard Frog, scientific name is Rana pipien).
Purpose: To observe characteristics that identifies the frog as an amphibian
Objectives:
Examine the frog and relate the structures to their functions
Determine how the frog’s characteristics enable it to live.
II. INTRODUCTION:
Background information should include the following:
Definition of “amphibian”
The period in time when they first appeared.
Describe the 3 groups of amphibians and include examples of members of each group.
Habitat of frogs
Life cycle of frogs
Ecology: Describe their importance to their environment and to humans.
III. MATERIAL & PROCEDURE (numerical):
a. List materials.
b. Clearly state step by step how you run your experiment. Avoid using "I" or "we" or copying and pasting from my handout. Summarize it! Make sure that your experiment is clearly described so that someone else can replicate it.
IV. DATA & OBSERVATIONS:
Attach the sketches and diagrams that you colored and label from the Virtual Frog Lab to this part of the lab.
V. CONCLUSION:
a. Analysis of Data: - Answer in full sentences, paragraph form.
1. What adaptations do frogs, toads, salamanders and caecilians have in common?
2. How many species of frogs and toads exist on Earth today?
3. Body Temperature: How are amphibians and mammals different in the way they control their body temperature? Use the words endotherm and ectotherm.
4. Digestive system: Compare and contrast the digestive system of an (amphibian) and a (mammal). How are they similar/different?
5. Respiration: How is the respiration system in amphibian larvae different from adult amphibians? (Think tadpole versus frog)
6. Circulation: Which organs that make up the
