2. Science Log Q3 week 7 Wednesday Feb 22:
What did the fossils you observed yesterday have in common? How did they differ from each other?
Heredity and Adaptation Course, 1.1: The Fossil Record

3. Observe fossil replicas
Organisms structures or traces, such as shells or teeth or bones, or imprints like the leaf shape, or are preserved remains of ancient life that is found in rocks. We call these fossils. These fossil replicas are copies, cast directly from the actual fossil itself, then cut in half. The color is approximate.

Step 5

4. Observe fossil replicas
Organisms structures or traces, such as shells or teeth or bones, or imprints like the leaf shape, or are preserved remains of ancient life that is found in rocks. We call these fossils. Discuss different ways you might categorize the fossils.

Step 5

5. The first thing you are going to look at in the course is the history of life as it has been recorded in rocks, the fossil record.

Time data
What the organism was
The environment the organism lived in

20. Discuss page 5
Discuss and think about what the diagram is and what information it is trying to communicate.
Heredity and Adaptation Course, 1.1: The Fossil Record

21. Discuss page 5
Discuss and think about what the diagram is and what information it is trying to communicate.
It is a type of time line, a graphic representation of chronological sequence of events; in this context, a representation of life-forms fossilized at different periods in time.
The diagram is a model used to explain the principle of superposition.
