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...

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...

In this tree observation worksheet, 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...

Learners study trees in their natural habitat. In this tree instructional activity, 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...

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.

Students 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.

Learners 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.

Learners work together to complete an experiment calculating the amount of board footage in a tree. They record their data and answer questions at the end of the lesson. They create their own hypothesis as well.
