Q22 (Question Booklet – Page 39, OEQ): PHPPS/2017/P6/SA2/Q33
Answer Update Q22a: The large intestine is responsible for absorbing excess water and mineral salts from undigested food before the undigested food is passed out of the body as stools. As the large intestine absorbed too little water from the undigested food, Jenny had watery stools.
Answer Update Q22b: The watery stools mean that Jenny’s body is absorbing less water into the bloodstream. Thus, she should drink more water so that her body has sufficient water, which is important for carrying out life processes.
Q24b (Question Booklet – Page 41, OEQ): NYPS/2017/P5/SA2/Q30
Answer Update: A smoker has less air sacs in the lungs for exchange of gases. Thus, the smoker has to breathe faster to take in more oxygen to allow for sufficient oxygen to be absorbed into the bloodstream. The oxygen is then transported through the bloodstream to all parts of the body and is used by the body cells for respiration to release sufficient energy.
Q25 (Question Booklet – Page 42-43, OEQ): ACSJ/2016/P5/CA1/Q22
Answer Update Q25b: The blood in blood vessel A contains more carbon dioxide than the blood in blood vessel C.
Answer Update Q25c: Choose: Blood sample S. Use data: The amount of oxygen in blood sample S was the least. Explain data: The blood carried in the blood vessel from the heart to the lungs has passed through the heart twice and the other parts of the body once. Hence, most amount of oxygen in the blood would have been used by the cells for respiration to release energy. This results in the least amount of oxygen in the blood.

Q7b (Question Booklet – Page 8, OEQ): MGS/2016/P6/SA2/Q38
P6 Answer (Updated): As material Y moved over the roller with magnets, the magnetic force of attraction acting on material Y was greater than the gravitational force acting on material Y, preventing it from falling into container P. However, as material Y moves further away from the roller with magnets, the magnetic force of attraction acting on material Y was smaller than the gravitational force acting on material Y, causing it to fall into container Q.
Q10b (Question Booklet – Page 11, OEQ): RSS/2017/P6/SA1/Q39
Amended Answer: The like poles of magnets Y and X are facing each other, causing them to repel, pushing magnet X up to balance the scale with the lighter object Q.
Q11b (Question Booklet – Page 14, OEQ): SCGS/2013/P5/SA2/Q36
Answer Update: There would not be any copper nails moving towards the iron sheet. The iron sheet is made of a magnetic material and does not allow the magnet’s magnetism to pass through it. The copper nails are made of a non-magnetic material and will not be attracted by the magnet.
Q12a (Question Booklet – Page 15, OEQ): HPPS/2015/P6/SA1/Q44
Add on for P6 students (Updated): The magnetic force of attraction acting on the metal clip was greater than the gravitational force acting on the metal clip, preventing it from dropping.
Q16b (Question Booklet – Page 20, OEQ): RSS/2013/P5/SA1/Q41
Updated Answer: When the power supply was cut off, no electric current flowed through the wires, causing the rods to lose their magnetism. Thus, the rods were no longer able to attract the nails, causing them to drop back into the container.
Q16c (Question Booklet – Page 20, OEQ): RSS/2013/P5/SA1/Q41
Amended answer: When the security guard switches on the power supply, there is a closed circuit with the coils of wire. Thus, electric current flows through the coils of wire, causing the iron core to be magnetised to become an electromagnet.
The electromagnet’s magnetism acts at a distance to attract the steel weight, which is made of a magnetic material. This exerts a pull force on the steel weight, causing it to move downwards and raise the barrier.
Q16d (Question Booklet – Page 20, OEQ): RSS/2013/P5/SA1/Q41
Amended answer: Increase the number of batteries in the circuit. OR Increase the number of coils of wire around the iron core.
Q17 (Question Booklet – Page 21, OEQ): RSS/2014/P6/SA1/Q40
Amended answer: When switch B is closed, … coils of wire. Electric current passes through the coils of wire, causing the iron rod to be magnetised to become an electromagnet. The electromagnet’s magnetism acts at a distance to attract steel contact Z, which is made of magnetic material. This causes steel contacts X and Y to lose contact with Z, creating an open circuit in circuit A, even with switch A closed. Thus, no electric current flows through the fan, preventing it from working.
Q18b (Question Booklet – Page 22, OEQ): SNGS/2015/P6/CA1/Q40
Amended answer: When electric current passed through the coil, the iron core was magnetised to become an electromagnet. The electromagnet’s magnetism acted at a distance to attract the iron disc, which is made of a magnetic material. This exerts a pull force on the spring balance, causing its reading to increase.
Q19a (Question Booklet – Page 23, OEQ): RGPS/2016/P6/SA1/Q39
Amended answer: Siti’s results. The magnetism of the horseshoe magnet is the strongest at its poles, which are parts A and E. Thus, parts A and E of the horseshoe magnet should attract the most number of iron nails, which is shown in Siti’s results.
Q20a (Question Booklet – Page 25, OEQ): TNS/2017/P5/SA2/Q38
Amended answer: When the switch is closed, there is a closed circuit with the coils of wire. Thus, electric current flows through the coils of wire, causing the iron bar to be magnetised to become an electromagnet.
Q22a (Question Booklet – Page 27, OEQ): SHHG/2013/P6/SA2/Q40
Add on for P6 students (Updated): The magnetic force of repulsion between the magnets is greater than the gravitational force acting on magnet X, causing magnet X to float above magnet Y.
Q23a (Question Booklet – Page 28, OEQ): MGS/2015/P5/SA1/Q39
Add on for P6 students (Updated): The magnetic force of attraction acting on the metal clip was greater than the gravitational force acting on the metal clip, causing it to remain in the air.
Q20a (Question Booklet Page 25, OEQ): TNS/2017/P5/SA2/Q38
Amended answer: When the switch is closed, there is a closed circuit with the coils of wire. Thus, electric current flows through the coils of wire, causing the iron bar to be magnetised to become an electromagnet. The electromagnet’s magnetism acts at a distance to attract the iron nails, which are made of a magnetic material, causing the iron nails to move towards the iron bar.

Q11b (Answer Booklet – Page 4, OEQ): SCGS/2013/P5/SA2/Q36
Answer Update: There would not be any copper nails moving towards the plastic sheet. The iron sheet is made of a magnetic material and does not allow the magnet’s magnetism to pass through it. The copper nails are made of a non-magnetic material and will not be attracted by the magnet.

Q1a (Question Booklet – Page 1, OEQ): RVPS/2012/P6/SA1/Q44
Answer Update: Include the additional parts in bold for a more complete answer:
The gravitational potential energy of metal ball A is converted to kinetic energy as it rolls down the ramp. Ball A lands on the wooden plank, pushing the left end of the wooden plank down. The kinetic energy of ball A is then transferred to the wooden plank, which is then converted to sound energy when the right end of the wooden plank moves upwards to hit the gong.
Alternative Answer Accepted:
The heavy metal ball A will roll down the ramp and push the left end of the wooden plank down. Thus, the right end of the wooden plank will move up and hit the gong, causing the gong to sound.
Q6c (Question Booklet – Page 7, OEQ): CHS/2015/P6/SA2/Q40
Answer Update Q6c: State the factor: Since ball S was released from a lower height from the ground, Use energy conversion: it possessed less gravitational potential energy, which was converted to less kinetic energy. When ball S hit marble X, less kinetic energy of ball S was transferred to marble X, and was then converted back to less gravitational potential energy of marble X. Thus, marble X rolled up to a lower height on the ramp and was unable to hit the bell.
Q10c (Question Booklet – Page 12, OEQ): NYPS/2017/P6/SA2/Q35
Answer Update Q10c: Observation 2: All of the kinetic energy of the cube had been converted to heat and sound energy. Thus, the metal cube no longer possessed kinetic energy and came to a stop at Point C.
Q19b (Question Booklet – Page 12, OEQ): NYPS/2017/P6/SA2/Q35
Answer Update 19b: Using the same type of plastic cards and rubber bands ensures that the mass of the cards and the stiffness of the rubber bands are kept the same and would not affect the maximum height reached by the toy. Thus, there would only be one changed variable, which is the number of rubber bands used that would affect the results of the experiment.
