Trees can be small, and trees can be big. How do we determine a tree’s size? How can we size up one tree versus another? In this activity designed for 3rd-8th graders, students work in teams and use one or several different methods to measure and compare the sizes of trees.
Note: Proposed NGSS alignment and 5E lesson structure (less Evaluate) are included in the activity guide. This activity was originally developed for Merced County Office of Education's TEAM-E Science Training for elementary and middle school teachers.
