Re: what is a mill worm and how does different surfaces affect the movement

I looked for info on mill worms and found nothing.  After thinking 
about your age and question I came to the conclusion that you meant 
mealworm.  (Tenebrio molitor)  This worm is a common worm found 
in pet stores and used to feed pet lizards.  They are not really a worm 
but the immature grub of the grain beetle.   They love to live in flour or 
cereal grains.  I have kept a colony going in bran flakes for a few 
years.   Because of  being a grub, the meal worm has small front 
legs that it uses to pull itself along.  It is very slow and would move 
differently according to the surface.  It may have more difficulty moving  
across a smooth suface like a desk but move better across fine sand 
paper or dirt something with a texture.  This sounds like a science 
project question.  I would try different  sufaces like wax paper,  regular 
paper, plastic surface, sand paper, etc.  a timer to time the movement 
would be helpful.  A Google search of "mealworm" sould get you lots 
of info.  I hope I have answered your question. Good luck!
