Educator Guide: Lab 1 - Launching an Expedition
NOTE: To get access to the Answer Keys for the TREX labs, you will need to 'Request Instructor Access' using the the tab in the navigation menu on the left side of this page. This is to ensure that students are not simply downloading answer keys. Once you get notification that you have been approved, come back to this site and click on the guide that you want. You will enter your email and the guide will automatically be sent to you. You can do this for each of the five labs. Please allow at least 48 hours for approval.
Summary and Learning Objectives
In Lab 1, students are charged with thinking about what it takes to "do science." They are introduced to the science of dendrochronology and learn how tree-ring science is done. What tools are used? What techniques can be used to prepare and analyze tree core samples to reveal the nature of past climate? They see how tree core samples are obtained and processed, and take a virtual tour of a tree-ring laboratory. Then they watch videos of two accomplished dendrochronologists describe their career path and the role serendipity has played. They take a virtual trip to a tree-ring lab and then consider what kinds of special trees scientists seek to help them answer questions about how our climate has changed in the past. Students then explore the tree-ring datasets available from the International Tree-Ring Databank (IRTB) and focus on the work of one of the science investigators, and their peer-reviewed research, to help them understand the nature of science.
Note: Please download the Student Activity Sheet (pdf or Word version) found in the Printable Materials section of this document if you wish to have students respond to Stop and Think questions as they go through the lab.
After completing this lab, students will be able to:
- describe what the science of dendrochronology is
- explain what types of trees give dendrochronologists the best chance to reconstruct past climate change.
- locate a tree-ring dataset from the International Tree-Ring Databank, and find a peer review publication that is associated with that dataset.
