Review on Graph Drawing

Reminders on graph drawing:

1. Graphs must be large and fill up at least 3/4 of the grid space provided.
   
   
2. Use a pencil to draw your graphs, and use a ruler when drawing in the axes.
   
   
3. X-axis: Represents either time (to show the progress of a reaction) or the independent variable (which is controlled by the experimenter), such as pH, temperature, concentration of solution.
   
   
4. Y-axis: Represents the dependent variable (ie the results obtained from the experiment), such as time taken for reaction to complete, reaction rate, length of potato strip.
   
   
5. Ensure that your axes are labelled, and units are given.
   
   
6. Ensure a suitable title is given, and underlined, eg. Graph showing the effect of temperature on rate of enzyme activity.
   
   
7. Mark points with small, neat crosses. Join points that show a trend/relationship with a best-fit line/curve.
