2. SIMULATIONS
Image 2.
This Google Site contains four reusable learning object
simulations designed by the University of Colorado at
Boulder. The University provides an open resource of fun,
interactive Science simulations that are designed to promote
conceptual understanding among learners as well as
promoting research-based activities. The Phet project
interactive simulations by the University of Colorado at
Boulder can be found at:-

3. DATA COLLECTION AND
PROCESSING INTERNAL
ASSESSMENT CRITERIA
Each interactive simulation is accompanied by a
learning task that will allow students to collect
research-based data from the interactive simulation.
This data can then be processed and can be presented
as a Data Collection and Processing (DCP) internal
assessment activity for the student IB Physics
internal assessment portfolio.
Each DCP learning activity is designed so that
students can work independently from one another,
therefore working at their own pace. Raw data
collected from the simulation will be specific to each
student.
Each student is solely responsible for all data
collection within their learning activity.
4. DATA COLLECTION AND PROCESSING
INTERNAL ASSESSMENT CRITERIA
The learning task for each simulation focuses on each
aspect of the IB - DCP internal assessment criteria
for Science and this rubric is shown below.

5. DATA COLLECTION AND
PROCESSING EXAMPLE
An electric toy car is travelling along a straight line
and measurements of its position and time are
taken. The uncertainty in the time ∆t = ± 0.005s
and the uncertainty of the displacement ∆s = ±
0.1m.

6. ASPECT 1
By manipulating the variables within the simulation,
students can collect all relevant raw data from the
simulation including all relevant units and errors.
Students can record and display this data using suitable
spreadsheet software that is applicable to them.
7. ASPECT 2
Students can manipulate and process data using suitable
spreadsheets and graphing software that is applicable to
the individual. Spreadsheets can be used to perform
calculations on raw data and to record processed data.
Graphing software can be used to find relationships
between variable data and provide physical constants
where appropriate.
8. ASPECT 3
Students can use functions of suitable spreadsheets and
graphing software that is applicable to them. For
graphing software this should include error
bar analysis where appropriate and for spreadsheet
software this should include organisation and
presentation of the overall DCP lab report.
10. FORCE AND MOTION SIMULATION
The DCP learning activity instructs students to
manipulate the relationship between the normal force
and friction force during translational equilibrium
and determines the physical quantity of coefficient of
friction using this relationship.

11. PENDULUM SIMULATION
The DCP learning activity instructs students to
manipulate the relationship between the length of a
pendulum and the period of the pendulum and
determines the physical quantity of gravity using this
relationship.
Fig 6.
12. BLACK BODY SIMULATION
This DCP learning activity instructs students to
manipulate the relationship between temperature
and intensity and determines the Stefan - Boltzmann
constant using this relationship.
Fig 7.
13. BENDING LIGHT SIMULATION
The DCP learning activity instructs students to
manipulate the relationship between the angle of
incidence and the angle of refraction using
monochromatic light and determine the physical
quantity of refractive index using the relationship of
the sine's of these angles.
