Height of a Kite

A kite is being flown with a lightweight, 100 ft. length of string. What other measurements might you use to compute an estimate of the height of the kite? Find four different methods that might be used with students at different grade levels.




How do you take account of the sag in the string? The direct line distance from the kite flyer's hand to the kite is less than 100 ft. How much less? in strong wind? in normal, kite flying wind?

Precision. How precise a measure is needed or reasonable in such a problem?

What is the difference between "precision" and "accuracy?"
