Some videos are longer than others, but they generally contain lots of information about how the instrument works and how it is played and sometimes information about the instrument’s history. Great website.

A teacher’s guide (could definitely be used by students for research purposes) to African musical instruments. Contains mostly pictures and text. PDF document.
Lots of information about the ukulele including, chords, brief history, tunings, etc…. Not the most in depth website, but covers a wide range of topics
