Controlled Assessment Part A: Planning Edexcel GSCE Science
Controlled Assessment Part B: Observations Edexcel GSCE Science
Controlled Assessment Part C: Conclusions
and Evaluation Variables Independent
Variable Dependent
Variable Control
Variables what you will
deliberately change... ...to measure the
effect on this what you will
keep the same for FAIR
TESTING identify all these
early in your work what values will you
choose, and why? HOW will you
control it? your will need to measure these two,
and put them in a results table.
You MIGHT need to measure some other
things and calculate these? Hypothesis A statement linking your
independent and dependent variables.
Your plan should then be about
how to test this statement Use scientific ideas
to justify your
hypothesis Plan Should refer to
your independent
and dependent variables How to measure them How to get the necessary
accuracy and precision What values of your
independent variable
will you choose? Why?
Think about the
data you will
end up with Selecting
Equipment Risk
assessment What are
the risks? What are the
consequences? How will you
manage the
risk? Primary
Evidence Secondary
Evidence Results
table Repeats all columns
labelled to
include units significant
about? Do you have some
evidence? And maybe some
evidence too? Have you
upon the
of the source
of your
evidence? How will you use
your measurements
to test your hypothesis Justify your
selection Graph Conclusion Evaluation Line of
best fit Quality of
evidence Identify
anomalies Deal with
anomalies What have you learned?
What does it say about the
hypothesis? Have you taken into account
ALL your evidence, when making
this conclusion? Have you explained
your conclusion with
scientific ideas? Evaluation
of conclusion Evaluation
of method Refer back to
quality of evidence How much do you trust
your conclusion? How could you
data so you could
trust your conclusion
more? How could you
data so you could
trust your conclusion
more? Strengths? WHY was it
a strength? Weaknesses? WHY was it
a weakness? Explain what led
to your anomalies Can you relate this
to the hypothesis? How do you know?
What effect did it have
on your data? What improvements
could you make? What effect would
you expect to see
on your data? a step-by-step
set of instructions range interval different
situations Have you described the patterns in your data IN DETAIL?
