Preparation for Dissections
Today's Webquest will help prepare you for Basic Dissections. You will also look at a frog dissection online (since we do not do those in class). Remember that there is always an alternative assignment to dissecting if you choose to not participate.
Open up Microsoft Word and Save your Document as "Last name - dissection.doc" in the G Drive Folder: Gibney Biology (1st or 3rd).
At the top of your Word Document type your name, today's date, and class period. Clearly label three sections in your document: Earthworm, Frog, Animal of Your Choice.
--------------------------------------------------------------------------------------------
Answer the Following Questions in order in your document.
EARTHWORM:
1. Figure out the Phylum -Class -Family -Genus -Species - of an ordinary earthworm
Visit http://biog-101-104.bio.cornell.edu/BIOG101_104/tutorials/animals/earthworm.html
2. Click on the external view of the earthworm. What is the big ring on an earthworm?
3. Describe five of the earthworm's internal organs and their functions (you can use any site for this).
4. Among the earthworm’s structural adaptations are its setae. How do you think the earthworm’s setae make it well adapted to its habitat? (Hint: you need to figure out what setae are)
5. How is the earthworm’s digestive system adapted for extracting relatively small amounts of food from large amounts of ingested soil?
FROG
1. Insert a picture of each system of the frog and describe each system in one sentence:
- Digestive
Nervous

2. Why might it be bad to dissect frogs? Find this online.

1. Choose an animal that you can find an online dissection of. Copy and paste the website into your word document. Describe in 5 sentences what you learned from the online dissection of this animal.
When you are done you may work on extra credit.
