Students are to create a Quizlet word list and print the "glossary", stapling it in their notebook. This is a large assignment and should be completed over time.

Fossils |
Read: Earth's Changing Surface "Fossils" (pp. 108-116)
Key Terms: Fossil, Mold, Cast, Petrified Fossil, Trace Fossil, Paleontologist, Scientific Theory, Evolution, Extinction Fossil Index
Homework: Bring in a small object to fossilize (trinket, shell, chicken bone, etc.) Some supplies we may need from home, ask you parents: freezer storage bags of grass cuttings, dried leaves, random very small pieces of organic yard stuff. Copy this chart in your notebook.

Relative Age & Radio Acitve Dating |
Read: Earth's Changing Surface "Relative Age of Rocks" (pp. 117-121)
& "Radioactive Dating" (pp. 123-126) Key Terms: Relative Age, Absolute Age, Index Fossil, Radioactive Decay, Half-life, Unconformity Relative Ages
To find the relative age of rocks, do you need to know their exact age? Explain. What is the principle of superposition? Animations & Graphics

Identify the type of unconformity shown. Is it possible that there were originally more layer of rock?
Describe how the rocks on the left of the fault moved in relation to the rocks on right. Hypothesize how the hill of the left side of the figure formed? |
Is it possible to conclude if the igneous intrusion on the left is older or younger than the nonconformity nearest to the surface?
Hypothesize which two layers of rock may have had been much thicker in the past. |

What is the difference between Carbon-12 and Carbon-13?
Why is Carbon-14 different from -12 & -13?
What happens to Carbon-14 after an organism dies?
What does Carbon-14 revert to in a decaying organism?
Is Carbon dating accurate? What could effect the dating results?
What is the half-life of Carbon?

What is the half-life of Carbon?
Jelly Bean Carbon-14 Dating
Procedure
- Count out 80 jelly beans.
- Remove half the red beans and replace them with green jelly beans.
- Continue replacing half the red jelly beans with green jelly beans until only 1 red jelly beans remain. Count the number of times you replaced half the red jelly beans.
Copy these questions. Skip three lines after each.
How did this activity model the decay of carbon-14 atoms?
How many half-lives of "carbon-14 did you model during this activity?
If the atoms in a bone experienced the same number of half lives as your jelly bans, how old would the bone be?
