Students construct a launch altitude tracker and use it, along with basic mathematics, to indirectly measure the altitude achieved by rockets.

Determining the altitude reached by a rocket is a relatively simple process using a handheld tracking device. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube. Using simple mathematics, students will calculate the altitude of the rocket. With two trackers in different locations, accuracy of the estimates can be improved.

The "Launch Altitude Tracker" activity is from the Rockets Educators Guide. Although grade levels are suggested, small modifications will enable more complex activities to be used successfully with other grade levels for observation, demonstration or complete lessons.
