Selected Learning Outcomes for Primary 5 Science Papers (2013)
The given classification chart shows the characteristics of eight different objects represented by A, B, C, D, W, X, Y and Z. The characteristics are flexible and waterproof. Students are supposed to describe object C and state the differences between object X and object Z. They are also to write down the letter of the object that best represents writing paper and glass.
Sally removed the outer ring of a stem of a plant. As a result, the tubes carrying food and water were removed. The labels A, X, Y and Z in diagram refers to stem, leaf below removed outer ring, leaf above removed outer ring and underground stem respectively. After a few days, Sally observed that the leaves at X remained green while those at Y had wilted. Z is an underground stem that can store food for the plant. Sally noticed that part Z grew bigger. Students are to explain the observations above and state what would happen to Z if the same cut had been made at A instead.
Jessica placed a healthy potted plant in the middle of the school field on a clear day and recorded the amount of oxygen produced by the plant from 6am to noon. The graph shows that the amount of oxygen drops with time. Her classmate Siew Ling commented that her graph is wrong. Pupils are required to be able to explain the reason and to draw the correct graph.
Students are shown the following electrical components: 3 bulbs, 3 switches, 2 batteries and some electric wires. Using only circuit symbols, they are expected to be able to draw a circuit diagram which satisfy the condition that only 1 bulb can be lit at a time. Students are required to state one advantage of connecting the lamps at home in a parallel circuit over using a series circuit.
A spirometer is a device which measures the amount of air that enters and leaves the lungs during breathing. A given graph shows Kelly’s breathing recorded by the spirometer during a period of 2 minutes. The curve shows minor fluctuations in the first 6 seconds followed by intense fluctuations in the next 1 minute. Students are to compare the graph for first minute to second minute, suggest what Kelly could have been doing during each period and comment on the heart beat rate after the first minute.
Uncle Ravi, a school bus driver, parks his bus at an open-air car park every night. When he went to his bus at 6 a.m. on Saturday morning, he found tiny water droplets on the windscreen and windows of his bus as shown in the given diagram. Students are required to explain clearly how the water droplets formed on the windscreen and the windows even though it did not rain the night before. Uncle Ravi returned to his bus at 10 a.m. that day and found that the water droplets were gone even though he had not wiped them away. Assuming no one else could have come to his bus, students are supposed to be able to state what could have happened to the water droplets.
