Credo of Geologic Evolution


									     ____________’s Credo of Geologic
        and Biological Evolution
Answer. Then tell us, why do you believe this answer? What’s
your proof or logic?“I know this is true b/c..”

Warm Up Questions

1. Read the attached account of how the world was created. Explain why you think it is true or not.

2. The night after a storm, you come in to the classroom to find a tree branch and broken window glass on the
floor. The floor is flooded with water, about 12 mm deep. By experimentation, you determine that rainwater
would come in a hole in the window that size at a rate that would cover the floor 2 mm every hour. What
happened in the room and how long ago did it happen?

Before You Start
A. What is your definition of truth?

B. How do you decide what is the truth and what isn’t?

1. How old is the earth?

2. How did the earth form? Describe what happened.

3. What evidence do/could scientists use to figure out what happened in earth’s ancient past?
(List as many as you can.) Do you think these are credible/valid ways to prove things we can’t
have seen? Explain.

4. Give your Top Five List: What are the five most important events in earth’s history? Give
your reason for choosing those.

5. Scientists created a timeline to organize earth’s history. How would you organize earth’s
history? What events would indicate where divisions should be made?

6. Describe the earth’s surface over the last 4.5 billion years. Has it changed? If so, how has it
changed as time has passed? What forces created these changes?

7. Is the earth still evolving? (Don’t forget – all your answers need to include why you think so.)
8. Where can you find fossils? How could you figure out how old a fossil was if you found one?

9. What did early forms of life look like? Why did they change?

10. Why are there no longer dinosaurs? How did the puny mammals survive while the powerful
dinosaurs died out?

11. What is evolution? Some people have strong feeling about it, most doen’t exactly
understand what it is. What do you think about it? What is the difference between believing and
knowing? Which does science use?

12. What forces/situations makes species evolve (change over generations)?

13. Of all species that have ever existed, 99.9% are extinct. Cockroaches and sharks, however,
have been around for millions of years. Not only have they not gone extinct, they’ve barely
changed. How do you think have they avoided extinction and major changes over time?

14. Define what you would call a human. (What makes a human, well, human?)

15. Define what you would call a hominid.

16. How long have humans been on earth? (This answer depends on what you said a human

17. Why do scientists believe modern humans evolved from ape-like primates?

18. Has there only been one kind of hominid/human species existing at a time?

19. T/F Dinosaurs and hominids/humans coexisted.

20. What is a mass extinction? What causes one?

21. How many major extinction periods have there been? Describe them.

22. Are we going through a mass extinction period now? How are humans involved?

23. If we are going through a mass extinction, describe the future of earth if this continues.

24, How do we know our climate is getting warmer? How would things change for us and the
planet if this warming continues?

25. Do you think humans will continue to evolve? If so, how will we change?
For warm up questions 1:

There are times when the universe takes form and times when it dissolves back into

Before time began there was no heaven, no earth and no space between. A vast dark
ocean of darkness washed upon the shores of nothingness and licked the edges of
A giant cobra floated on the waters. Asleep within its endless coils lay the Lord Vishnu.
He was watched over by the mighty serpent. Everything was so peaceful and silent
that Vishnu slept undisturbed by dreams or motion.
From the depths a humming sound, Om, began to tremble. It grew and spread, filling
the emptiness with energy. The night had ended. Vishnu awoke. As the dawn began to
break, from Vishnu's navel grew a magnificent lotus flower. In the middle of the
blossom sat Vishnu's servant, Brahma. He awaited the Lord's command.
Vishnu spoke to his servant: 'It is time to begin.' Brahma bowed. Vishnu commanded:

A wind swept up the waters. Vishnu and the serpent vanished. Brahma remained in
the lotus flower, floating and tossing on the sea. He lifted up his arms and calmed the
wind and the ocean. Then Brahma split the lotus flower into three. He stretched one
part into the heavens. He made another part into the earth. With the third part of the
flower he created the skies.
The earth was bare. Brahma set to work. He created grass, flowers, trees and plants
of all kinds. To these he gave feeling. Next he created the animals and the insects to
live on the land. He made birds to fly in the air and many fish to swim in the sea. To
all these creatures, he gave the senses of touch and smell. He gave them power to
see, hear and move.
The world was soon bristling with life and the air was filled with the sounds of
Brahma's creation.
