Presentation Transcript

  1. Bell work • What could you study by using a telescope? • What could you study by using a microscope? • Write your answers in your science journal.

  2. Measurement notes

  3. Objectives for today • Describe three kinds of tools. • Explain the importance of the International System of Units. • Describe how to measure length, area, mass, volume, and temperature. • Identify lab safety symbols, and demonstrate safe practices during lab investigations.

  4. Units of Measurement • The International System of Units Begun by the French Academy of Sciences in the late 1700s, the SI is used by almost all countries in the world. • All SI units are based on the number 10, which makes conversion from one unit to another easy.

  5. Length • Measurement from one point to another • SI-Meter • English Standard-inches, feet, yards, miles

  6. Area • Measurement of a surface • Area=length x width • SI-meters squared • English Standard-inches squared, feet squared, yards squared, miles squared, acres

  7. Volume • measurement of space taken up • SI-liter • English standard-liquid oz, cup, pint, quart, gallon

  8. Mass • Measurement of matter, what it is made up of • SI-kilogram • English Standard-solid oz. and pounds

  9. Weight • Measurement of the pull of gravity on an object • SI-kilogram • English Standard- solid oz. and pounds

  10. Temperature • Measurement of hot/cold • SI- Celsius or Kelvin • English Standard-Fahrenheit

  11. Objectives for today • Describe three kinds of tools. • Explain the importance of the International System of Units. • Describe how to measure length, area, mass, volume, and temperature. • Identify lab safety symbols, and demonstrate safe practices during lab investigations.

  12. Tools for Science • Tools for Seeing • Microscopes, hand lenses, telescopes • Tools for Measuring • stopwatches, metersticks, balances, thermometers, spring scales, and graduated cylinders • Tools for Analyzing • calculators, computers, and a pencil and paper

  13. Measurement tools
