Throughout the ages, people have proposed many strange diverse theories about the earth. It was flat; its flat surface was encased in a huge half-globe to which the stars were attached; it was the center of the universe; these are just a few of the mistaken ideas people have held. Our understanding of the earth and the skies today is the result of centuries of scientific study and discoveries, and the invention of effective scientific tools to make possible and to verify these findings. The Globe Kit is a working earth model which enable students to solve various problems in such broad topics as earth measurement, astronomy, and seismology. It is a versatile tool to investigate many different problems in science and should not be restricted merely to the investigations wich are included in the manual.
