  3. Examples of experiments 1 • How does fertilizer affect the growth rate of plants? • we set up an experiment testing different amounts of fertilizer on different plants & measuring the growth (height) of the plants: • dependent variable (Y-axis)? • ________________________ • independent variable (X-axis)? • ________________________ The effect of _____________on _____________

  4. Examples of experiments 2 • How does exercise affect heart rate of 10th grade student? • we set up an experiment testing different lengths of time of exercise (minutes) on the heart rate of students: • dependent variable (Y-axis)? • ________________________ • independent variable (X-axis)? • ________________________ The effect of _____________on _____________

  5. Examples of experiments 3 • What’s the favorite drink of students? • we set up an experiment surveying students and asking which is their favorite drink : • dependent variable (Y-axis)? • ________________________ • independent variable (X-axis)? • ________________________ The effect of _____________on _____________

  6. Making pictures out of data How’s a critterto choose? • Graphs • ___________________________ • graphing data that shows continuous change • ___________________________ • graphing data that is in disconnected groups
