What is a cool yet simple science project for a third grader?
um… last year (7th grade) my friend did a project that was pretty simple.. all you do is get 2 kinda of bird food(if you live somewhere that has birds) and pick maybe a kind of bird thats what they did… and count how many (of those birds) eat from which one… they got first in the science fair from this project and i only requires counting… and buying supplies…
