PART B Paper 3 Planning Experiment Tips for Paper 3 No 1 1. Identify the variables from the text and Diagram (a) Manipulated variable (b) Responding variable (c) Fixed variable ( can be measured) (NOT TYPE OF SUBSTANCE) (d) Observe the diagram measurement (e) Identify the value in the table (f) Tabulate data with symbol and unit. (g) Plan your graph (unit and symbol) (h) Determine the relationship from the graph Tips for Paper 3 No 2 2. Read the question CAREFULLY (a) Extrapolate the graph and write the value next to the highest and lowest point of the graph (b) Plot BIGGEST TRIANGLE and get the closest value with the units. (c) Determine the value correctly with 2 decimal places. (d) PRECAUTION WRITING Observe the reading of the ammeter/ METER RULE perpendicular to the eyes to prevent parallax errors. Turn off the circuit when measurement of current on ammeter is NOT TAKEN to prevent heating of wires and cause systematic errors. (NO MORE WRITE) Repeat the experiment for several times/ 3 times and determine the average value to prevent systematic error. 3. PART B Planning Experiment (a) Identify the MV and RV from the diagram and questions. CIRCLE IT UP. (b) Identify the apparatus given on the question which relate to the PHYSICS CONCEPT of experiment. (c) Recall and relate the experiment which you had done before in school laboratory and identify the relationship between the TWO variables. (d) DON T QUOTE BACK the questions variables. It will make the whole planning experiment get maximum 2 marks. Paper 2 Part B 1. Definition don t state the formula of the define word - Write the definition in statement from the formula 2. Comparison questions must use back the same diagram to compare in physics term comparison. Quote back the Diagram number, and compare with statement according to the marks provision. 3. Explanation on aspects given. Must quote back the aspect given, don t divert the statement by explaning other statement of your ways. 4. Explain the characteristics of the statement given follow ( 1 marks) with explanation of the benefit and advantages of the characteristics stated. (1 marks) 5. More explanation are better, usually TWO are more than enough. Part C 1. Usually calculation, and definition. Please state formula, working and final results with minimum 2 decimal places and correct units. 2. Explanation of physics concepts, usually test your understanding of physics formula relationships. 2 000002 02
3. Study specification on the aspects given and evaluate the pictures given to extract the answer from the information given. Quote the information of point of answer and elaborate the statement of characterics with physics concept explanation. 4. Try to give TWO explanation of each characterics in a statement. (4 points with 4 explanation) 8 marks 5. Final 2 marks is the explanation of the BEST suitability and CHOOSE the BEST of the 4 or 5 given examples. 6. This characteristics and explanation can states in a table form. (THE BEST EVER ESSAY for 10 marks) 7. Choose the best essay than you can get the MOST marks. 8. Essay in Part B and Part C is usually ONE form 4 and ONE form 5. So DON T SPOT QUESTION. Study all the physics concept. 3 000003 03
USCI Workshop 2017 1. Rajah 3.1 menunjukkan seorang pemuda duduk bersendirian di atas sebuah bangku yang berada di atas tanah yang lembut, dia mendapati kaki bangku itu tidak tenggelam ke dalam tanah. Diagram 3.1 shows a teenager sat alone on top a benches on a soft soil, he noticed the leg of the benches never sink into the soil. Rajah 3.2 menunjukkan kaki bangku tenggelam ke dalam tanah apabila seorang pemuda lain duduk di atas bangku itu bersamanya. Diagram 3.2 shows the leg of the benches sank into the soil when another teenager sat on the benches together. Rajah 3.1 Rajah 3.2 Dengan menggunakan radas seperti pemberat, plastisin dan radas lain terangkan satu eksperimen untuk menyiasat hipotesis yang dinyatakan di 3(b). Using the apparatus as load, plasticine and other apparatus, explain an experiment to investigate the hypothesis stated in 3 (b) 2. Rajah 4.1 menunjukkan pesongan ammeter adalah kecil apabila suis dihidupkan dan reostat dilaraskan pada satu kedudukan. Bunyi loceng yang kedengaran adalah perlahan. Diagram 4.1 shows the small deflection of ammeter when switch is turn on and rheostat set at one position. The bell ring slowly. Rajah 4.2 menunjukkan pesongan jarum ammeter adalah lebih besar apabila suis dihidupkan dan reostat dilaraskan pada kedudukan yang berbeza. Bunyi loceng yang kedengaran adalah lebih kuat. Diagram 4.2 shows the bigger deflection of ammeter when switch is turn on and rheostat set at another position. The bell ring louder. 2 www.guruthong.wordpress.com
Rajah 4.1 Rajah 4.2 (a) Dengan menggunakan radas seperti bateri, teras besi lembut,dawai kuprum bertebat, dawai penyambung dan radas lain, terangkan satu eksperimen untuk menyiasat hipotesis yang dinyatakan di 4(b). Using the apparatus such as battery, soft iron core, insulated copper wire, connecting wire and other apparatus, explain an experiment to investigate the hypothesis stated in 4 (b) 3. Diagram 3 shows two similar coffee maker A and B, containing different amount of coffee on similar hot plates stove. The coffee in both coffee makers are heated by turning on the power supply of the hot plate. After few minutes, it was observed that the coffee in coffee maker B is hotter than the coffee in coffee maker A. Rajah 3 menunjukkan dua pembancuh kopi serupa A dan B, mengandungi jumlah kopi yang berbeza di atas dapur plat panas yang serupa. Kopi di dalam keduadua pembancuh kopi dipanaskan dengan menghidupkan bekalan kuasa plat panas. Selepas beberapa minit, didapati kopi dalam pembancuh kopi B adalah lebih panas daripada kopi dalam pembancuh kopi A.
