Measurement Graphing

  1. 1. Scientific Measurements<br />Student will be able to<br />Understand why scientist use a standard measure<br />Describe the standard units of measure<br />Describe common measure used in science<br />Analyze graphing in science<br />
  2. 2. <ul><li> Common Practice</li></ul>44<br />
  3. 3. 59<br /><ul><li> Measurement Systems</li></ul>English System (red)<br />Metric System<br />
  4. 4. <ul><li>Metric System Prefixes</li></ul> kilo (k) means 1,000 x<br /> centi (c) means 0.01 x<br /> milli (m) means 0.001 x<br /> micro (µ) means 0.000001 x<br />45<br />
  5. 5. <ul><li> Length (how long)</li></ul> - Measured in Meter (m)<br />+ Kilometer (km)<br />+ Centimeter (cm)<br />+ Millimeter (mm)<br />+ Micrometer (µm)<br />46<br />
  6. 6. <ul><li> Mass (how much stuff)</li></ul>Gram (g)<br />+ Kilogram (kg)<br />+ Milligram (mg)<br />48<br />
  7. 7. <ul><li> Volume (how much space)
  8. 8. Liter (l)</li></ul>+ Milliliter (ml)<br />50<br />
  9. 9. <ul><li> Time</li></ul>Second<br />53<br />
  10. 10. <ul><li> Temperature (movement)</li></ul> Celsius<br /> Kelvin<br />54<br />
  11. 11. <ul><li> Estimation</li></ul>61<br />
  12. 12. <ul><li> Accuracy & Precision</li></ul>Accuracy = How close is it to real value<br />Precision = How close is each measurement to each other<br />62<br />
  13. 13. • Mean, Median, Mode<br /><ul><li> Mean = Average
  14. 14. Median = Middle
  15. 15. Mode = Most often</li></ul>66<br />
  16. 16. • Graphs<br />
  17. 17. - Graphs vs. Text<br />At age 1, Sarah was 75 cm tall. By the time she turned 2, Sarah had grown 10 cm. By age 3, she had grown another 10 cm. At age 4, Sarah was 100 cm tall.<br />+ Which is better?<br />68<br />
  18. 18. - Line Graphs<br />+ Example Experiment – Boiling Water<br />70<br />
  19. 19. - Line Graph<br />+ Draw Axis<br />√ X “What you changed”<br />√ Y “What was measured”<br />+ Create Scale<br />+ Plot Data<br />+ Draw best fit line<br />71<br />
  20. 20. - Best Fit Line<br />+ Follow general trend<br />+ Include as many points as possible<br />+ Have same # of points above and below<br />72<br />
  21. 21. - Identify Trends<br />74<br />
  22. 22. Worksheet<br />
