Physical Science Ch 2, sec 1 tools in science

  1. 1. Section 1 Tools and Models in Science<br />Chapter 2<br />Tools in Science<br />A tool is anything that helps you do a task. <br />Scientists use many different tools to help them make observations, take measurements, and analyze data.<br />
  2. 2. Section 1 Tools and Models in Science<br />Chapter 2<br />Making Measurements<br />The International System of Units (SI) is the standard system of measurement. All SI units are expressed in multiples of 10. <br />Prefixes are used to express SI units that are larger or smaller than basic units. For example, kilo- means 1,000 times, and milli- indicates 1/1,000 times.<br />
  3. 3. Section 1 Tools and Models in Science<br />Chapter 2<br />Making Measurements, continued<br />Length, mass, volume, density, and temperature are common measurements.<br />The meter is the basic SI unit of length.<br />The kilogram (kg) is the basic SI unit for mass. Mass is the measure of the amount of matter in an object.<br />
  4. 4. Section 1 Tools and Models in Science<br />Chapter 2<br />Making Measurements, continued<br />Liquid volume is expressed in liters (L). Volume is a measure of the size of an object in three-dimensional space.<br />The volume of solid objects is usually expressed in cubic meters (m3).<br />
  5. 5. Section 1 Tools and Models in Science<br />Chapter 2<br />Making Measurements, continued<br />Density is the ratio of the mass of a substance to the volume of the substance.<br />The temperature of a substance is a measurement of how hot the substance is.<br />The kelvin (K) is the SI unit for temperature.<br />
  6. 6. Data in Science<br />Chapter 2<br />
  7. 7. Section 1 Tools and Models in Science<br />Chapter 2<br />Models in Science<br />A model is a representation of an object or system. A model uses something familiar to help you understand something that is not familiar.<br />Physical, conceptual, and mathematical models are commonly used in science.<br />Models have limitations because they are never exactly like the real thing.<br />
  8. 8. Section 1 Tools and Models in Science<br />Chapter 2<br />Using Models for Scientific Progress<br />In science, a theory is a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation.<br />In science, a law is a descriptive statement or equation that reliably predicts events under certain conditions.<br />
