If you really want students to wrap their mind around the concept of what falling objects do and aren't "clinging" to the insistence of obtaining the absolute precision of 9.81 m/s² in the lab, then the g Ball is exactly what you're looking for!
Drop the g Ball from 3 meters, 2 meters, 1 meter, and from 50cm in height using d=1/2 at 2 with the measured time will result in a ~10m/s² every time! The ball has a timer that is started manually with a push of a button at the instant it is released or thrown. When the ball strikes a surface, the timing stops and the time of flight is recorded. The cool thing about using the g Ball is that it can be used anywhere; outdoors to measure the height of the flagpole, the speed of a student pitch in the hallway, in the conventional lab setting, without the need for computers, expensive data collectors or complicated devices.
