Day 7

Topic Dendrochronology

Objectives
Use cross-dating techniques to find out how old a tree is.

State Goals

Classwork-Homework
On the Board
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.

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?

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 embyo (fingers unentwined 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).

Carrot Tops Cut about half an inch off the end of the carrot that has the leaves. Cut the leaves off close to the base of the carrot. Put the carrots into the container with the cut side down.
Add enough water to cover about half the carrot top. Place the container in a well-lighted window. Observe the carrot tops each day for any changes. Remember the changes may start out small and change slowly. Look for new leaves and roots. Use a metric ruler to measure any growth you may observe. Continue your observations for six days and write your report on the sixth day. Make a chart to record any changes and measurements. Bring the carrot top and the chart to class.
