Select a temperature range (Normal, Cool, or Warm) and a precipitation amount (Normal, Dry, or Wet) for the coming year. The tree (which you are viewing a cross-section of the trunk of) grows one year's worth, adding a new ring.

Add some rings while varying the temperature and precipitation.

Which of these factors has a stronger influence on the growth of the type of tree being modeled here? The "Show Specimen Tree" button displays a section of an "actual" tree specimen.

Can you model the annual climate during each year of the specimen tree's life, matching your diagram with the specimen, to determine the climate history "written" in the rings of the specimen tree? Many educators are now finding opportunities to teach about Earth's climate and climate change in their classrooms.

However, when the interpretation of scientific data contradicts the true history of the world as revealed in the Bible, then it’s the interpretation of the data that is at fault.

It’s important to remember that we have limited data, and new discoveries have often overturned previous ‘hard facts’.

This worksheet gives a basic overview of tree rings for your little scientist.

The first macro measures ring width marked by the user on scanned images, stores raw and detrended data in Excel and calculates the distance to the pith and inter-series correlations.

This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.

A tree ring pattern that matches is found close to where the carbon ‘dates’ are the same. It assumes that it is approximately correct to linearly extrapolate the carbon ‘clock’ backwards. The closer one gets back to the Flood the more inaccurate the linear extrapolation of the carbon ‘clock’ would become, perhaps radically so.

According to David Rohl, the Sweet Track chronology from Southwest England was ‘re-measured’ when it did not agree with the published dendrochronology from Northern Ireland (Belfast).

Also, the construction of a detailed sequence from southern Germany was abandoned in deference to the Belfast chronology, even though the authors of the German study had been confident of its accuracy until the Belfast one was published.
