ISA:
ISA Your teacher will suggest as method for the investigation as you will not be assessed on this Then you will be assessed on: - Drawing a results table Carrying out the experiment Drawing a graph Completing the final exam section 1 related to your experiment, section 2 related to the area of science The following slides will help you design the following: - Drawing a results table Drawing a graph Saturday, March 12, 2011
Table:
Table Try to make it easy to read Have clear titles for your rows and columns Include units in the titles Allow enough columns to collect repeats and work out an average
Table:
Table Your table should include your independent variable (usually on the left hand column); your dependent variable with appropriate repeats and an average; and specific units needed for all data… Independent Variable (UNITS) Dependent Variable (UNITS) 1 2 3 Average A B C D E
Graphing:
Graphing Use as much of the piece of graph paper as you can Carefully label the axis using an appropriate scale (starting at 0) Give the graph a sensible title Carefully plot points Draw a line of best fit (which may be curved) (Note: do not join up the dots!) If you are drawing a bar chart: remember the key and make sure the bars are even sizes And lastly remember a ruler and pencil
Graphing:
Graphing It is vital you choose the appropriate graph… Bar chart – used when independent variable is categoric and the dependent variable is continuous Scattergram – used to see how variables relate to each other (e.g. people’s age and size)
Graphing:
Graphing Ensure you choose the appropriate graph; choose your scale; add a title, labels and units; plot points carefully and clearly; and draw a line of best fit
