5 values is standard
Belongs on the X-axis of a graph
Is manipulated/ changed during the expiriment
Belongs on the Y-axis of a graph
Range of values and their units
ex: 5g, 10g, 15g, 20g, 25g
Number of trials
ex: 3 trials is standard
Is measured during the expiriment
Data collected may be graph, or may need to be converted first
ex:
Raw data - not graphed
Averages calculated - graphed
Independent Variable
Dependent Variable
Control variables the experimental design or data collection. They must be in order to keep the results .
Ex: The research question of an experiment is 'How does the amount of water affect plant growth?" One control variable might be , as it could affect the results of the independent variables or between trials. To keep their results reliable, they will control for this with .

| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Axis Title | arrow_right_alt | lives on the X-axis |
Scale | arrow_right_alt | lives on the Y-axis |
Independent Variable | arrow_right_alt | the trend in the data is linear/ makes the shape of a line |
Outlier | arrow_right_alt | the trend in the data is exponential/ curves |
Dependent Variable | arrow_right_alt | includes variable and units |
Line Graph/Scatter Plot | arrow_right_alt | is often the Research Question |
(0,0) | arrow_right_alt | drawn in pencil with and X not a dot |
Graph Title | arrow_right_alt | at least one variable is Categorical data |
Plotted points | arrow_right_alt | both variables are numerical/ measurable |
Exponential best fit line | arrow_right_alt | appropriately spaced on grid paper |
Linear best fit line | arrow_right_alt | the intersection (crossing point) of the X and Y axis |
Bar Graph | arrow_right_alt | a data point which is far from the Best fit line |
Categorize each as either an elements of Conclusion or Evaluation/ Analysis
*drag each element into one category*
Is there enough data?
ex: 5 IV values and 3 trials is standard
What were the sources of error? How did they affect the experiment? How could you have controlled for them?
Describe the data trends
Are your data points reliable?
ex: can they fit on a best fit line? Are there too many outliers?
Describe the effect of the IV on the DV, with evidence from the data
Evaluate the validity of your experiment
If you could continue this experiment, what would you investigate next?
Further scientific reasoning that supports (or explains the faults in) your hypothesis
Was you method reliable?
ex: were your measurements percise enough?
Does the evidence support your Hypothesis?
