Class:
Date:

2. 1 . DESIGN (D)
AIM/RESEARCH QUESTION-: state what you are investigating (IV) and how you will
investigate it (DV)
To investigate
HYPOTHESIS- make a prediction, how does changing the IV effect the DV
If
then
SCIENTIFIC EXPLANATION- explain your hypothesis using scientific reasoning
VARIABLES - state the IV, DV and at least 3 control variables with Units
Independent variable:
Dependent variable:
First control variable:
Second Control Variable:
Third Control Variable:

3. CONTROLLING VARIABLES -
Independent: explain how you will change the IV and what apparatus will use do to this
Dependant: explain how you will measure the DV and what apparatus will use do to this
Control: explain how you will control at least 3 variables and the apparatus used to do this

APPARATUS AND MATERIALS - List the apparatus you are going to use. :
include concentrations of solutions and size of equipment 2M solution, 50ml Beaker
Draw and label your diagram in pencil.

4. METHOD/PROCEDURE - include ALL steps, correct units, range of samples. State what you
will do with the data and calculate a mean/draw a graph etc

5. 2. DATA COLLECTION AND PROCESSING (DCP)
RAW AND PROCESSED DATA TABLE - Use the table below to make a note of your results. You do not have to use all the cells in the
table. Use the dotted lines as a guide . A titled large clear table with all raw and processed data. Include headings/ units
Title: …………………………………………………………………………………………………………………………………………………………….
· Have you remembered units and headings?

6. GRAPH - Make a bar or line graph of your results below with correctly plotted with Scale, axis, labels.
Units and title (SALT)
Title: Graph showing the relationship between …………………………………….

7. DATA ANALYSIS - describe your results in words by identifying trends and patterns.
E.g. At………… there was the greatest distance diffused by NaOH (0.76mm) At…..there was the lowest
distance of diffusion.

8. 3. DISCUSSION, EVALUATION AND CONCLUSION (DEC)
DISCUSSION
Explanation and Scientific Reasoning
Suggest possible explanation for anomalous results
Limitations of the Experiment, (validity and reliability)- identify errors in the method, measurements and
limitations in collecting data (do not include your human errors).
Was your experiment valid and reliable?
VALID
RELIABLE
And Suggestions for Improvements how to realistically improve the limitations you have identified
Weakness in method and/or apparatus Suggestion for improvement

9. Relationship to hypothesis and Research Question - do your results and validity/reliability of the
experiment support or disprove your initial hypothesis
What can you say about your hypothesis?
A. My hypothesis is supported
B. My hypothesis should be changed to ………………………………………
………………………………………………………………………………
………………………………………………………………………………
………………………………………………………………………………
C. My results do not allow me to choose A or B ( can you suggest further experiments or
improvements to improve your investigation
………………………………………………………………………………
………………………………………………………………………………
………………………………………………………………………………
CONCLUSION- summarize report and refer back to research question(s), briefly state the trends on
patterns, comment on validity and reliability, and conclude whether data supports or disproves your
hypothesis. If possible relate to real world context and include ideas for further study (extension of
investigation)
