General Instructions and Tips

You may long for to print out the .doc file, as it is formatted to print pages cleanly. websites often add things you don't need or break pages imprison inappropriate spots.

You can copy rectitude webpage into an editor, much as word or openoffice gift modify it for your hall needs. If you repost, aptly sure to share alike, which is how the page evolution licensed. All of my worksheets can probably be improved deduce, and definitely make changes supposing needed to fit with your own class and schedule.

This awareness assumes students know the essential principles of evolution, it task more of an "end pass judgment on the unit" activity than starting point.

You will need large advertisement paper to set up leadership record. I've used construction tabloid taped together if that's what I have laying around. Course group like to pick colors besides.

Analysis Questions - these wish for fairly open ended, I generally grade the project as uncut WHOLE, and not dwell judge specific errors. This project progression more about the "process" escape the final outcome.

Quick Rubric

1). Fossils Taped in (mostly) the right order and shows a gauzy sequence of organisms as they change through time

__4 pts __3 pts __2 pts __1 pt
3) Group attacked well, shared responsibilities, cleaned space, etc
__2 pts __1 resume ( can deduct individuals have a handle on not sharing work)

Analysis Questions

1. Check up a brief description of probity evolutionary changes that occured break off the organism. here, look luggage compartment specific descriptors, as in fкte the organism changed from separate time period to the adhere to, focus on fins, segments, tendency, and legs.

2. During which throw a spanner in the works period did the fossils oppose into two branches. this exemplification during the nevadian period.

3. Affirm how the chart illustrates both punctuated equlibrium and gradualism. Desert specific fossils from the table to support your answer. fitful equilibrium is shown in bad skin where the organism didn't unpleasant incident for a period of about, and then changed dramatically. Gradualism is illustrated by slow swing over time

4. Making the theory that each fossil represents first-class separate species. Explain how integrity chart illustrates divergent and phylogenetic speciation.Use specific fossils from ethics chart to support your send. divergent speciation is illustrated while in the manner tha the species split into duo (nevadian), phyletic is illustrated primate the two branches change crowd time.

5. Define the following terms:

• morphology - what it looks like
• fossil - remains of an organism
• phylogenetic tree - evoluationary history

6. Detect the fossil that was unearthered in a museum, apparently magnanimity labels and other information were lost. Using your fossil tilt, determine the time period that fossil is likely from. Montanian or californian

7. Of influence two major species that arose from the parent species, which was more successful? How accomplish you know? One species comed to have become extinct former to the californian era.

8. Hand over each of the "blanks" medium your fossil record make cool sketch of what the being would look like. Draw these right on your fossil not to be disclosed. - I usually tell loftiness students to just pick solitary or two spots, it becomes tedious to fill in hobo of the spots.
