Miami Beach Sr. High School
Mr. C. Rodriguez

The Internal Assessments that are sent to IB
must be your own. No group work is allowed.

You will be graded in three categories:
 A) Design
 B) Data Collection and Processing
 C) Evaluation
• Each of the categories listed above will be graded at
least twice, with the two highest scores sent to IB.

Aspect #1

Formulates a focused research statement and identifies relevant
variables.
 Make sure your research statement is clear and explains what you
expect to prove in the experiment.
 You should clearly identify your independent, dependent variables and
any control variables in the lab.


Aspect #2
Designs a method for the effective control of
the variables.
 Procedure should be clear, and in number form.
 Include amounts such as mass, concentration,
chemicals to be used, equipment used.
 Make sure that every variable that was mentioned
in Aspect #1 is addressed in procedure.


Aspect #3
Develops a method that allows for the collection
of sufficient relevant data.

Make sure to collect at least 5 sets of data in the
lab.

Make sure that the procedure you created allows
you to collect data that can answer your
Research Question.


Aspect #1
Records appropriate quantitative and
associated qualitative raw data, including units
and uncertainties when necessary.


Should be in table form.
Anything measured in Lab, must be found in this
table.
Include units and uncertainties
Add a Qualitative Data section.




Aspect #2
Processes the quantitative raw data
correctly.

Make sure to have a title for the calculation
performed.
Show calculation clearly.
Show calculation for error analysis.
Create Graph and use it appropriately.
Compare to Book value if possible. Percent
error.


Aspect #3
Presents processed data appropriately and
when relevant, includes errors and
uncertainties.
Table of Processed data with units and
uncertainties.
Include any % errors calculated.

Aspect #1 States a conclusion, with justification, based on
a reasonable interpretation of the data.

Need to make sure to use your data to back up your
conclusion

You can show sample calculations to support your conclusion

Aspect #2 Evaluates weaknesses and limitations.

You must address uncertainties here, percent error, are your
errors random or systematic. Name those errors.

Make sure you address here where is your largest error
coming from and how did it affect your results.

This aspect is only graded once and there is no information
sent to IB for moderation.

Is based on what your teacher’s observations on how well
you follow instructions and use` lab equipment.

The final score here will be moderated based on how IB
moderated the other three categories. So if you were
deducted on design, data collection and Conclusion. You will
then also be lowered here.

This aspect will aslo be graded once and there is no paper
sent to IB other than your score.

This is based on your Group IV Project. How well you
performed as part of a group. You presentation of the
project.

The final score here will be moderated based on how IB
moderated the other three categories. So if you were
deducted on design, data collection and Conclusion. You will
then also be lowered here.

As you have seen, there are five components that will make
your IA score.


Design: 2 labs x 6 points each= 12
Data Analysis: 2 labs x 6 points each= 12
Evaluation: 2 labs x 6 points each= 12
Manipulative skills: 6
Personal skills: 6





Total points: 48
After moderating the first three categories, your score will
be moderated across all 5 categories.

Aspect #3 Suggest realistic improvements in respect of
identified weaknesses and limitations.

Here is where you MUST suggest improvements that
address each of the problems you listed in aspect #2.

Make sure that the suggestions, actually address the
problem.
 Example: If the problem was your density value was too low, and you
identified the volume reading as a problem, then make sure the
volume measurement correction that you suggest will actually give
you a higher density value.
