The Scientific Method
![Page 6: FTCE Chemistry SAE Preparation Course](https://reader030.vdocuments.site/reader030/viewer/2022033021/568166cc550346895ddad8fc/html5/thumbnails/6.jpg)
Parts Of An Experiment
• Constant– The elements of an experiment that remain
unchanged throughout the duration of the trials• Control
– A part of the experiment that does not have the independent variable applied to it. (Think Comparison)
• Independent Variable– The variable that is applied to the experiment,
causes a change in the dependent variable• Dependent Variable
– The variable that is measured in the experiment.

Types of Data
• Qualitative Data– Qualities– Descriptive
• Quantitative Data– Numbers– Counted or Estimated
![Page 8: FTCE Chemistry SAE Preparation Course](https://reader030.vdocuments.site/reader030/viewer/2022033021/568166cc550346895ddad8fc/html5/thumbnails/8.jpg)
Scientific Data
• Accurate– Data collected are within a close range of an
accepted or correct value• Precise
– Data collected are within a close range of each other
• Systematic Error– Differences in data collection that can be predicted
theories, laws or technology application• Random Error
– Differences in data collection that result from human error or environmental variances
![Page 9: FTCE Chemistry SAE Preparation Course](https://reader030.vdocuments.site/reader030/viewer/2022033021/568166cc550346895ddad8fc/html5/thumbnails/9.jpg)
Parts of an Experiment
• Experimental evidence– Data collected from an experiment that
can be used to validate results from repeated trials
• Models– A visual or mathematical aid created
using repeated experimental data to predict or represent items in nature
![Page 10: FTCE Chemistry SAE Preparation Course](https://reader030.vdocuments.site/reader030/viewer/2022033021/568166cc550346895ddad8fc/html5/thumbnails/10.jpg)
Parts of Scientific Methodology
• Observations– Data collected using the senses during or before an
experiment• Assumptions
– Similar to Hypotheses, a guess about a situation in nature
• Hypotheses– An educated guess about a problem based upon
observations and background information• Theories
– A statement that consistently predicts a pattern in nature• Laws
– A mathematical statement that consistently predicts a pattern in nature

Areas of Scientific Study
• Basic scientific research – No particular goal in mind– Research to learn more about nature
• Applied research– Specific goal or desired product– Research to acquire desired results
• Technology– Tools used within scientific study to gain
insight and collect further data
