Assessment Task

Motors & Generators Open-Ended Investigation

Due Date: Monday 9th April 2001

Weighting: 15% Outcomes Assessed H1 evaluates how major advances in scientific understanding and technology have changed the direction or nature of scientific

thinking H2 analyses the ways in which models, theories and laws in physics have been tested and validated H11 justifies the appropriateness of a particular investigation plan H12 evaluates ways in which accuracy and reliability could be improved in investigations H13 uses terminology and reporting styles appropriately and successfully to communicate information and understanding H14 assesses the validity of conclusions drawn from gathered data and information

Content In this assessment task, you will investigate one type of motor or generator studied in this topic. You are to design and/or evaluate a type of motor.

Format The assessment is to be presented in three parts:

1. Log Book This section details an account of your investigation. Your research, thoughts, resources, contacts list and other details are to be recorded in this section.

2. Model This may be the schematics, a working model, non-working model, animation, video or other suitable demonstration of the model you are investigating.

3. Report This is to be in the standard report format (refer to the handout “Experimental Report Writing in HSC Science”). You should include a research section and/or the principles of an electric motor. A bibliography of all referenced work is to be included.

• While there is no word limit on this task, it is anticipated that you would spend approximately 15 – 20 hours TOTAL on the research, design, evaluation and reporting in this task.

• Students must NOT buy kits to build their motors. Marks will not be allocated on the basis of whether model do or do not work. Marks are allocated on the evidence of the underlying scientific principles and appropriate design. Do NOT waste time trying to make the model work.

• The power source for the motor must not exceed 12V AC/DC.
