SHARK BODY PARTS
By Deborah Crabtree
University of Idaho
Bill Nye The Science Guy #203
In this lesson the students will learn the body parts of the
shark. They will label them on a diagram, and be able to identify the body parts. They
will look in-depth at the gills and the fins by watching the Bill Nye show.
- Students will be able to list all the parts on the shark and
label a diagram of the shark anatomy.
- They will also be able to define the words, "gill and
fin" and describe what they are used for.
Introduce the class to the poster of the shark that is hanging on the board. Introduce the
vocabulary. Then discuss the parts of a shark. Point to each part on the poster, and say
the name out loud. Ask the students, "What is different on a shark than on a
fish that you may catch in the river?" Bring up the skin and scale differences. Ask
the students if they know what "cartilage" is. Discuss how sharks have cartilage
and not bones.
Provide a focus for students:
The focus for viewing is to give the students a clear understanding of how fish
have gills to breathe, and fins to propel them through the water. The students will also
compare the differences between sharks and fish. The students will be encouraged to look
for reasons that sharks have gills and fins, and how they help the shark live its daily
Begin the Video at the point just after the
"bubble 007" part and right before Bill Nye starts to talk about gills.
Stop the Video after the child in the fish market talks about gills. Do not go on to the
part about scales.
Ask the students what gills are for? Make sure that they understand that gills are just
like our mouths and noses, and it is how fish breathe.
Fast Forward to the part where Bill Nye talks about fins. This is right after the two
girls talk about how to make an aquarium. Resume the video and watch the part about
Stop the Video when the "Fishing Derby" comes on. This is right after Bill Nye
is in the canoe. Discuss what fins are for, and why humans don't need them. Ask why we use
"fins" on our feet when we swim.
Fast Forward to the part where Bill Nye talks about Sharks.
Resume the Video and play the section of sharks.
Stop the Video when the "Fish and Chips" part comes on. Discuss with the class
how sharks are different from other fish, and how they are similar. Discuss the cartilage
that they have in their bodies instead of bones.
Post Viewing Activities:
Discuss with students what they have learned from
Bill Nye. What are some of their favorite facts? Discuss the body parts that
you saw before the video, and the ones you learned about in the video. Have students
label the body parts worksheet.

your own copy!
National geographic has a great web site on
where you can learn about shark facts, get hooked up to sites that allow you to talk to
oceanographers and biologists about sharks.
Have students write a detailed description of the
shark they drew in art. Remind students to give as much information as possible. (Size,
color, shape, number of eyes, etc.)
