I HAVE A BONE TO PICK WITH YOU
In this lesson students will become familiar with fossils. Through
video, they will observe how fossils are found by paleontologists. Students
will also compare the time when dinosaurs lived to when humans came to Earth.
Bill Nye: The Science Guy, Dinosaurs
Students will be able to:
- define a fossil.
- make a fossil of their own.
- compare the time period of dinosaurs to humans living on Earth.
- discuss the job of paleontologists.
- 25 sponges cut in the shape of a bone
- 50 cups of sand
- 2 boxes of salt
- 25 1/2 gallon milk cartons
- 25 clock worksheets
- 1 Judy clock
Teacher: Does anyone know what the word fossil means? (List
responses on the board.) In Latin, fossil means "something that has
been dug up." Becoming a fossil is not an easy thing. An animal or
a plant has to die and then it has to get buried by erosion or rain falls
down and washes dirt down and covers it.
Teacher: We're going to watch a segment of video about fossils
from Maiasaura dinosaurs. I want you to watch for three things. (Write the
three times on the board.)
1. How much did the Maiasauras weigh?
2. How did they keep their eggs warm?
3. How many eggs did they lay at a time?
I want you to write the three answers down on a piece of scratch paper.
CUE video to where Bill Nye says "This is a piece
of a backbone from a Maiasaura. BEGIN video. PAUSE #1 - Pause
at segment when Bill Nye says, "Maisasuras always ate their vegetables."
Review the answers to the three questions. Teacher: Dinosaurs and humans
did not live on Earth at the same time. Dinosaurs lived 65 million years
ago. In the video, a young girl gives us an idea of just how long ago that
was. After viewing this, you should be able to tell me where the first living
things appeared. BEGIN video. (FAST FORWARD to young girl
saying, "Just to five us scientist an idea of how much time that is,
picture this clock as a clock of time.") PAUSE #2 - Pause where
girl says, "Science is cool!!" Discuss where the first living
things appeared. Review what the girl did with a hand held Judy clock. have
a worksheet with 24 clocks on it representing every hour in a day. As a
group, make on the clocks when the Earth began to form, when the first living
things appeared, when dinosaurs arrived, and when humans existed on Earth.
This will help students compare the time spans. Teacher: Who can tell me
what the scientists are called that explores fossils? They are called paleontologist.
We will be listening to a paleontologist tell us about her job. You need
to find out why their jobs are important to us today even though dinosaurs
lived so long ago. RESUME video. (fast forward to the picture that
says, "Way Cool Scientist." PAUSE #3 - Pause when picture
returns to "Way Cool Scientist." Teacher: Why is it important
to learn about dinosaurs? Right. They may help us learn more about our ecosystem
and ways to improve it. We have learned why fossils are important to us.
Let's make our own fossils.
Students will make their own fossils.
1. Fill milk cartons with 2 cups of sand.
2. Mix 100 ml of slat with 250 ml of water and stir.
3. Bury "bone" sponges in sand.
4. Pour water mixture over sand.
5. Let set in window for 3-5 days.
6. Dig for the bone. (The salt crystals form in the holes of the sponge
making it stiff and hard like a fossil.)
Take a field trip to University of Kansas Museum of Natural
history in Lawrence, Kansas. There are many fossil exhibits to view.
Another filed trip to take is to Line Creek Archeological Museum. Students
participate in a simulated archeological dig.
Find a person in the community that is interested in fossils to visit you
Have students find information about paleontologists and fossils on the
Internet. Compile all information and make a newsletter about their discoveries
Science and Art: With butcher paper and paint, have students
walk, run, hop, skip, walk on hands and feet with paint. Notice how different
kinds of movements. Compare that to how different dinosaurs moved.
Music: Learn music video. "Mr. Dino" from Bill Nye tape and perform
it for another class.
Language Arts: Students pretend they are paleontologist. The will write
a story that begins, "One day, as I was digging for fossils, I dug
up a __________________! Here's what happened!"
