Additional Activities on Fossils
Use Geologic Time Scale to help students understand how old the Earth is: http://www.enchantedlearning.com/subjects/Geologictime.html
Discuss that Earth started out with different plants and animals than we know today that have become extinct over time. Point out the following using the Geologic Time Line:
- 3.9 to 2.5 billion years ago - animals were only single (one) celled
- 540 to 500 million years ago - one of the first complex animals was the trilobite
- Have students look at drawings of trilobites.
- 248 million years ago - first dinosaurs
- 146 million years ago - dinosaurs die out
- 54 million years ago - first mammals
- 24 million years ago - first horses, dogs and bears
- 5 million years ago - first whale
- 1.8 million years ago - first man (Mention what a small time man has been on Earth compared to how old Earth is.)
Use a piece of yard as a timeline to illustrate the age of the Earth. Using a scale of 1 mm = 1 million years, a time line of the Earth would be about 4.6 meters long. Show the ages of the items listed above on the timeline. (Note a mm is the size of the edge of a dime when looking at the side.)
United Streaming TLC Elementary School: Prehistoric Earth (Total Time 24:33) - Show Segment 3 Events in Earth's Past (6:11)
Ask students to tell you how man knows about the animals that lived on Earth such a long time ago.
(Encourage students to come up with the word fossil.)
What is a fossil?
Go over the definition of a fossil.
Fossils are the preserved remains of plants and animals or traces left by plants and animals such as footprints.
Explain how fossils are made.
Some animals were quickly buried after they died in mud or sand
Over time more and more sand and mud covered their bodies.
The bones and teeth turned into fossils over time.
The bone slowly decayed and water than contained minerals soaked into the the empty places. The minerals filled up the bone.
The process resulted in a rock-like copy of the original object which is a fossil.
