Ninety-nine Science Project Ideas

By Dr. Michael N. Farney

Director of the South Central South Dakota Science and Engineering Fair

 

This page is for busy teachers to hand out to their students.  Its ideas should excite kids from grades 6-12.  Many commercial devices, kits, and instruments are included; one can order nearly everything on-line for less than $20.00.  I selected the websites and the merchandise based on quality and potential interest.
