This time line goes back to the ancient world of Pythagoras, Aristotle and Archimedes, to the medieval world of Copernicus and Galileo, up to the modern world of Edison and Einstein. With a total of twenty-one illustrations many of the world's most notable scientists will be brought to life for your student. All the figures are dated with a brief explanation concerning the discoveries of each individual. Your student will more fully appreciate the progress of science through the centuries. With their dated illustrations of significant events and individuals, students cut and color the detailed drawings and paste them on two 6" x 34" card-stock strips which are scored and able to fold for convenient storage in the student notebook. Many students will mount their completed time lines on the wall. They stretch to nearly six feet in length! Used in our History of Science study!
