How do you measure the height of a tree (or building) without being a monkey? Probably your parents will not let you climb to the tip-top of the tree with a measuring tape.

Instead you can make our Tree Height Gage with paper, a straw, tape, string and a weight like a washer. You will also need someway to measure distance on the ground (tape measure or yardstick) and a friend to help you keep your gauge level.  Print this page out and follow the directions.Kids measure the height of a tree without being a monkey
