Project Time Frame
This project examines tree stumps in order to learn more about the properties of trees.
- To examine the ways in which tree rings reveal information about the world.
- To develop new and improved methods of analysis.
- To uncover information previously unknown about tree rings.
Materials and Equipment
- Computer with internet access.
- Access to actual tree stumps
- Digital camera
- Typical office/craft supplies (such as paper, pens & poster-board)
It’s commonly believed that the rings on a tree stump reveal the age (in years) of the tree itself. But tree rings may reveal more than just the age of a tree. This project aims to discover new ideas through a careful analysis of tree rings.
- How are tree rings formed?
- What causes a tree to grow one new ring every calendar year?
- How can tree ring characteristics be used to obtain other types of measurements?
- Does a tree stump keep adding new rings after the tree is chopped down?
- What else can we learn from tree rings?
Terms and Concepts to Start Background Research
- Read overviews of relevant topics (see bibliography and terms listed above).
- Collect a number of digital photos of tree rings, both online and with your own camera.
- If possible, also collect some actual tree ring samples.
- Analyze, describe and categorize each sample and photo.
- Develop and test your own theories about tree rings.
- Interpret your findings in a detailed report.
- Show results visually using charts and graphs.
- Display any interesting photos taken throughout the course of the experiment.
