Physics Practical Work Assessment

Construct 1: PLANNING OF PROCEDURES FOR INVESTIGATIONS OR EXPERIMENTS

Construct For Assessment

Criteria (Performance Indicator) (PI) Score

Planning Investigation Or Experiment

P1: State the inference corresponding to the situation or observation

P2: State the corresponding hypothesis in which its validity can be tested

P3: State the aim of the experiment or investigation that can verify the hypothesis stated

P4: State the manipulated variable (MV), the responding variable (RV), the constant/fixed variable

Score 3Able to achieve all PIs accurately and completely without assistance

Score 2Able to achieve at least 2 PIs correctly


P1: State the list of all apparatus and materials used to obtain at least one set of MV and RV data

P2: Describe the arrangement of the apparatus or draw and labeled diagram that is functional

P3: State completely the experimental procedures, including the method of controlling MV in the appropriate range and to measure the corresponding RV

P4: Show the table with their variables and corresponding units or correct observations.




*Note: Student who does not give any response or unable to achieve any PI will be marked “Y”.

Construct 2: CARRYING OUT INVESTIGATION OR EXPERIMENT



Carry Out Experiment Or Investigation

P1: Arrange and set up the apparatus, materials and/or equipment according to procedures or stated method correctly and functional

P2: Handle the apparatus, materials and/or equipment according to procedures or stated method correctly

P3: Record readings using the correct method and technique

Construct 3: COLLECT AND RECORD INVESTIGATIVE OR EXPERIMENTAL DATA



Collect And Record Investigative Or Experimental Data

P1: Construct a table consisting of rows and columns with the correct physical quantities and units

P2: Record all readings for manipulated variable with appropriate decimal places and consistent.

P3: Record the readings for responding variable with appropriate decimal places and consistent

P4: Record all the calculated secondary data with appropriate decimal places, consistent and in correct units (if applicable)





Construct 4: INTERPRET THE DATA AND DO THE CONCLUSION



Interpret The Data And Do The Conclusion

P1: State the title of the graph and draw the graph axis with correct unit, which is RV at y-axis and MV at x-axis

P2: The graph scale is uniform, not odd scale and at least four points transfer correctly

P3: The most suitable and smooth line with the line pattern matching with the experiment and size of the graph at least 50% of the graph paper

P4: Show how to determine the gradient of the graph with drawing the triangle and state the value of the graph gradient (if applicable)

P5: Determine the required values from the graph by using extrapolation or intrapolation (if applicable)

P6: State the conclusion based on the experiment

P7: State the precautionary steps taken to increase the accuracy of the result (if applicable)

Construct 5: SCIENTIFIC SKILLS AND NOBLE VALUES



Interest and curiosity

Systematic

Co-operative

Responsible

P1: Varieties, plenty and relevant. Always ask question to obtain extra information than required.

P2: Neat, proper and in sequence.

P3: Always willing to help others. Able to accept others people view.

P4: Practice safety measures and cleanliness. Carry out task within the allocated time.
