The Size of an Atom LAB Introduction: In this particular experiment we are to measure the properties of certain substances using methods that cannot be done with standard measurement tools, such as a ruler, scale, or clock. For instance to find the size of the molecule of oleic acid we shall use an indirect method. If we know the volume of the oleic acid and the area it spreads out to; we should be able to determine the thickness of an oleic acid molecule. Keeping in mind that for this to occur, the chemical properties of this acid as similar to that of oil. This means that once a droplet of the substance is placed on water it will spread out into a monolayer (typically one molecular high). We’ll use indirect methods to find the volume. Essentially we’re going to use volume/area= Thickness. Procedure: Once the tray is filled up with water about 1 cm high, the Lycopodium powder should be added lightly as if it were seasoning for the water. ...

Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not fals...
