Transcript

  1. Graphing Data Showing patterns & trends 2010-2011
  2. Types of data (information) <ul><li>Variables </li></ul><ul><ul><li>dependent variable </li></ul></ul><ul><ul><ul><li>measured variable </li></ul></ul></ul><ul><ul><ul><li>unpredictable change : we don’t know how it will change until we do the investigation </li></ul></ul></ul><ul><ul><ul><li>Y-axis </li></ul></ul></ul><ul><ul><li>independent variable </li></ul></ul><ul><ul><ul><li>manipulated variable </li></ul></ul></ul><ul><ul><ul><li>predictable change : it only changes because we chose how it would change </li></ul></ul></ul><ul><ul><ul><li>X-axis </li></ul></ul></ul><ul><ul><li>Constant Variables </li></ul></ul><ul><ul><ul><li>Remain the same throughout the experiment </li></ul></ul></ul>Physical Science The effect of _____________ on _____________ Independent Variable Dependent Variable
  3. Examples of experiment - A <ul><li>How does volume of sample affect the mass of a metal? </li></ul><ul><ul><li>we set up an experiment massing different size cubes of the same metal </li></ul></ul><ul><ul><ul><li>dependent variable (Y-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>Mass of cube </li></ul></ul></ul></ul><ul><ul><ul><li>independent variable (X-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>Volume of cube) </li></ul></ul></ul></ul>Physical Science The effect of _____________ on _____________ volume Mass of a metal
  4. Examples of experiments -B <ul><li>How does initial height affect final velocity of a dropped ball? </li></ul><ul><ul><li>we set up an experiment testing different initial heights (m) on the final velocity (in m/s) of a dropped basketball: </li></ul></ul><ul><ul><ul><li>dependent variable (Y-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>Final velocity(m/s) </li></ul></ul></ul></ul><ul><ul><ul><li>independent variable (X-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>Initial height (m) </li></ul></ul></ul></ul>Physical Science The effect of on ____ Initial Height Final velocity
  5. Examples of experiments C <ul><li>What’s the favorite candy bar of students? </li></ul><ul><ul><li>we set up an experiment surveying students and asking which is their favorite candy bar : </li></ul></ul><ul><ul><ul><li>dependent variable (Y-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>number of students </li></ul></ul></ul></ul><ul><ul><ul><li>independent variable (X-axis)? </li></ul></ul></ul><ul><ul><ul><ul><li>type of candy </li></ul></ul></ul></ul>Physical Science The effect of _____________ on _____________ Candy Bar type Number of students
  6. Making pictures out of data <ul><li>Graphs </li></ul><ul><ul><li>line graph </li></ul></ul><ul><ul><ul><li>Use when data shows a trend or continuous change </li></ul></ul></ul><ul><ul><li>bar graph (or histograms) </li></ul></ul><ul><ul><ul><li>Use when graphing data that is in disconnected groups </li></ul></ul></ul>Physical Science
  7. Physical Science How does elevation affect temperature? elevation Temperature (•C) 1200 ft? 18 Line graph ! 5 10 15 20 25 30 0 500 1000 1500 2000 2500 0 elevation (feet above sea level) temp. (°C) 0 30 500 25 1000 20 1500 15 2000 10 2500 5 1200
