This site offers help with procedures, particularly in areas which have been observed to cause problems to some students; and unstructured problems with clues and questions. The first problem attempts to emulate the thinking used in the development of classical physics from Aristarchus to Newton. Problems include topics in Prealgebra (solved problems designed to illustrate systematic styles of solution); Finding sizes and distances of earth, moon and sun as the ancient Greeks did (but using more accurate data in some cases  also see if you can jump from seeing an apple fall from a tree, as Newton did, to explaining the motion of the moon around the earth. Calculus would be helpful for this); Why is sunset in winter later in Boca Raton, FL than in Philadelphia, PA?
