The goal of this building block is to communicate the possibilities that the dendrochronology method offers. This includes the age dating of wood, the relationship between growth and climate, and the possibility of retrospect (reconstruction). It enables the evaluation of climate developments and their effects on humans (agriculture, construction style etc.) but also perspectives for the future based on available scenarios.
This building block uses two “sliding boards”:
- The first board shows the principle of age dating. An age dating trial with two wood samples can be conducted by sliding the board.
- The second board shows the relationship between climate and the width of the annual growth rings (using an example from Marchfeld). Printed on the glass board are various climate parameters and average time spans. In this way it is possible to discover which parameter and time frame produce the best relationship.
Additionally, an approximately 90 minute long lecture has been put together, including PowerPoint slides and commentary.
Application during the course
The sliding glass boards can be used in connection to the lecture or independent of it. The boards explain the basic principles of dendrochronology and the relationship to climate (Lecture with Power-Point slides and accompanying commentary. Use of sliding glass boards to enable understanding of basic principles.)
Aha-effect for Students
- Dating a piece of wood and its climate information
The boards are stored (and/or displayed) in the Institut für Holztechnologie und Nachwachsende Rohstoffe am UFT in Tulln. They can be borrowed upon arrangement.
