How to Weigh a Tree

Goal: The students will gain an appreciation of their dynamic interaction in the carbon cycle. They will learn the role of trees in counterbalancing the CO₂ that people produce. 

Prerequisites: Students should know how to measure in inches; if fractions of inches are used they need to be converted to decimal form in the web page calculators and the Excel spreadsheet.

Students should be able to pace off a distance and convert it to feet.

Students must be able to read tables.

Materials: String to measure circumference of a tree

Ruler or yardstick

Computer with Internet access or downloaded and saved models and tables.

A local tree which you can identify and measure.
