ARISTOTLE Aristotle is considered the father of today's scientific method. He was especially interested in biology, in classifying plants and animals in a way that would make sense. HOW WOULD YOU PROVE HOW DENSITY WORKS USING THE SCIENTIFIC METHOD?	ANAXAGORAS He discovered that the moon shines due to reflected light form the Sun, and he studied mixtures of matter. HOW WOULD YOU PROVE DIFFERENT SEPARATION TECHNIQUES FOR MIXTURES?	HIPPOCRATES OF COS Considered the "father of medicine". He thought that the body has 4 substances: blood, phlegm, yellow bile, and black bile. HOW WOULD YOU IDENTIFY MIXTURES AND PURE SUBSTANCES IN THE HUMAN BODY?
ANAXIMANDER First person who proposed that life comes from liquid water. HOW WOULD YOU PROVE THAT WATER CHANGES STATE?	DEMOCRITUS First philosopher who stated that the Universe is made up of atoms. HOW WOULD YOU PROVE THE ORGANIZATION OF THESE ATOMS IN THE DIFFERENT STATES OF MATTER?	THALES OF MILETUS Thales was the first true mathematician, he used geometry to solve problems such as calculating the height of pyramids and the distance of ships from the shore. HOW WOULD YOU MEASURE THE HEIGHT OF THE SCHOOL?
PYTHAGORAS Pythagoras was interested in music and maths, two ways of making order out of chaos. He studied areas, and he is best known for proving the Pythagorean Theorem. HOW WOULD YOU USE THIS PRINCIPLE IN AN EXPERIMENT?	ARCHIMEDES Considered the greatest mathematician of antiquity, he proved a range of geometrical theorems about area, surface area and volume. The most known one is the Archimedes´ Principle. HOW WOULD YOU PROVE THIS PRINCIPLE IS RIGHT?	EMPEDOCLES Originator of the Theory of the Four Roots (everything is made up of four elements: fire, water, air and earth). HOW WOULD YOU PROVE AIR IS MATTER?
