I need the scientific explanation of how and why some cockroaches can climb and others can't for my science fair project.

 
Climbing species have on tarsus a hairy structure called "pulvillo" (I don't know the english word.... sorry) that permits to cling to every kind of surface... exactly like little hooks under gecko's feet do... :)
