Experiment Guide

  1. 1. Experiment Guide Sarah Jones Source: fabianoefner.com
  2. 2. Laboratory Report Title Aim Hypothesis Materials Method Results Discussion Conclusion
  3. 3. Variables Independent Variable – What I will change. Dependent Variable – What I will measure. Control – What I will keep the same.
  4. 4. Hypothesis A hypothesis is a statement that describes a relationship between two or more variables that can be tested. http://www.k12tlc.net/quests/science/forcestd.htm
  5. 5. If the INDEPENDENT VARIABLE is CHANGED, then SOMETHING HAPPENS to the DEPENDENT VARIABLE. Example: If the height of the ramp is increased then there is an increase in the distance the car travels.
  6. 6. Results
  7. 7. Independent Variable DependentVariable
  8. 8. Observations Qualitative Written descriptions Drawings Photographs Taped interviews
  9. 9. Quantitative Raw data Presented data
  10. 10. Discussion The discussion has three sections. 1. Summary 2. Analysis 3. Evaluation
  11. 11. Summary: Write an overview of what was done and what happened. Refer to specific results e.g. the average distance was 43.9 cm
  12. 12. Analysis: Were the results expected? Write about why you think these results were obtained. Use your scientific knowledge and further scientific evidence to explain your results. Refer to specific results and tends in your tables, graphs and diagrams.
  13. 13. Evaluation: What were the variables in this experiment. Which variable was changed? Was the experiment a fair test? Comment on any possible errors in the experiment. In what way could the experiment be improved?
  14. 14. Conclusion Restate the hypothesis. Did the results support or refute the hypothesis? How did the results show this?
