LET'S INVENTORY THE SCHOOL FOREST

You'll find everything but the kitchen sink here ... or just a carbon sink. In the activity, pairs or groups of middle school learners go outside and measure a tree's circumference and height to estimate its carbon storage potential and...

In this tree observation activity, students pick a tree that they observe over the course of a school year. They make observations, they sketch the tree, they take photographs of the tree, they get a leaf sample. They estimate the tree...

With 90 percent of its land area covered in forests, Suriname, a country in South America, contains the largest percentage of forests throughout the world. Here is an activity that brings classmates together to learn about the...

Students examine tree rings to determine its age.  In this tree ring lesson, students examine core tree samples, identify the tree rings, and then determine its age. Students complete a worksheet, deciding which of the two core sample is...

Students study trees in their natural habitat. In this tree lesson, students complete a number of outdoor activities to estimate the height of a tree, examine how bark can be a distinguishing tree characteristic, and how to make a bark...

Learners observe trees in their neighborhood. They practice tree identification and incorporate math skills to determine the winner of a 'Tree-mendous Tree' contest in which they determine which is the biggest tree.

Seventh graders use their observation and measurement skills to identify trees. Using a tree diagram, they label the parts and discuss the functions of the tree. They practice using a dichotomous key to identify trees as well.

Middle schoolers work together to measure tree heights. They make predictions on what they believe the calculations are and answer questions during the experiment. They share their results with the class.

Students study how scientists have estimated the maximum height to which trees can grow, and assess the reliability of interpolation and extrapolation techniques by making predictions with particular data sets and analyzing accuracy of...

Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.
