Frog Dissection

Introduction:

· What do the internal structures of the frog look like?

· How do amphibian organs compare to human organs?

· This activity will give you practice and some knowledge before we begin the real dissection experience.

Description:

1. Explore the web site

Virtual Frog Dissection

2. Working in small groups of three or four, locate the body parts and organs listed on the lab sheet.
3. Manipulate the virtual frog via commands in the program.
4. Discuss and share their computer experiences.

Procedure:

1. All work will be done in small cooperative groups (2-3 students).
2. Each group will be assigned to one computer and given lab sheets.
3. Open up the website link. Locate each organ listed on the frog diagram on the computer screen.
4. "Click" on the organ. Copy the organ function listed at the top of window.
5. "Click" on the green organ link at the top of the page. Sketch the picture given with plenty of detail.
6. Remove the organ as directed. Continue with the next organ listed on the sheet.
7. When you have completed the assignment place it in my inbox.

Evaluation: Group participation, discussion participation, and completion of lab sheet.
