Description: How do we know that atoms and molecules really exist? This films helps prove their existence through circumstantial evidence just like a crime scene investigation. Very well made and does have some solid evidence for the existence and proof of atoms and molecules. https://www.youtube.com/channel/UCFdKnjmeaUvJ4ZJmENHwCCA

Complete Record: Uses a variety of indirect evidence to show the existence of molecules and atoms. A series of experiments in molecular motion and formation of crystals are demonstrated. Views of crystal structure by means of X-ray diffraction, the electron microscope, and the ion microscope give evidence as to molecular arrangements. Concludes with a demonstration of different reactions of identically appearing liquids.
