Cross dating:
Compares the growth rings from one tree to the growth rings of another tree
Tree rings: circles in cross sections of tree trunks; each pair of light and dark rings represents a year's growth.
Increment borer: a hollow instrument used to drill into the center of a tree to remove a core sample.

Tree Ring Coring  1:17


 Lecture.gif - 2227 Bytes  How Cross Dating Works

1 Scientists take a core sample from a living tree with reliable annual rings.
These were conifer trees growing in the American Southwest.
2 By counting backwards starting with the outer ring (the current year) they can
 assign each ring a year, then figure out when the tree sprouted and how old it is.
3 find an older tree to compare with a younger tree. 
                   -same kind of tree
                   -grown in the same area
                   -must have been alive for part of the time that the younger tree was growing
4 Compare rings to find a match.
5 Assign the same dates to overlapping rings.
6 Find older trees and overlap them


   Reading the Rings Part 2

1 Pass out page 24, a cross section from a tree that was used to build an Oklahoma farmhouse.
2 Students must find out when the farmhouse was built by finding out when the tree started growing and when it was cut down.
3 They will also discover some other events during the tree's life.
4 Cut out each core sample.  Only one matches.
5 Match up one of the core samples.  Do not go through the middle of the tree.
6 Count backwards to find the actual date when the  core sample matches the cross section.
7 Answer these questions.  Student Copy of Questions
1. In what year did the tree sprout?
2. In what year was it cut down?
3. In what year did a fire damage the tree?
4. How many years did it take for the dead branch to be covered?
5. In what year did a drought begin?  
6. How long did the drought last?
7. How old was the tree when it was cut down? 
8. The farmhouse was abandoned in 1933 only three years after it was built.
    Look at the core sample around the year 1933.  What was happening?

Pollen Grain:

Fertilization:

Pollination:
movement of pollen from a stamen to a pistil

PowerTeaching  Of Conifer Life Cycle
For cone we decided on hands over head in a cone shape.
Then we talked about the cone makes pollen (two hands low in front of you on left side wiggling).
The pollen pollinates (two hands move in arc to top right side) the ovule (two hands making an O).
This fertilizes the egg which makes a zygote (hands clasped together fingers entwined - showing sperm and egg united).
This grows into an embryo (fingers unintertwined and spread, but hands still together).
Which grows into a seedling (hands spreading apart).
Which grows into a tree (feet together, arms out like branches).
Which then makes more comes (arms back over hear in cone shape).
