🔍 Top Tested Topics in 2024 PSLE Science: Booklet A (Multiple-Choice Questions/ MCQ)
Booklet A consists of multiple-choice questions (MCQs) that assess foundational understanding and application.
Based on the 2024 paper, these are the heaviest weighted Booklet A topics:
💡 These 10+ topics make up over 70% of Booklet A!
✅ Top MCQ Tips from Our PSLE Science Specialists":
🧠 1. Always check units and values.
Many students lose marks from careless reading of graphs (e.g. giving “56mm” instead of increase of 6mm).
🔍 2. Eliminate wrong answers first.
As part of the H.U.A.T. answering technique, our students are trained to apply elimination before choosing – especially when options seem similar.
📊 3. Watch out for commonly confused concepts.
Heat vs temperature, magnetism vs electromagnetism, material properties like flexibility vs strength—these often trick students.
📝 4. Practise with real exam paper.
We use PSLE-style MCQ questions in our Science classes so students get used to the question rigor and phrasing.
🔍 Top Tested Topics in 2024 PSLE Science: Booklet B (Open-Ended Questions/ OEQ)
Booklet B is where students often lose the most marks—not due to content gaps, but due to weak answering techniques.
These are the top weighted topics for Booklet B (based on 2024 analysis):
✍️ Using BlueTree A.B.C. Answering Technique To Score Full Marks in Science OEQ
🔎 FAQ-Style Tips for Open-Ended Questions (Booklet B)
Q1: Why does my child keep losing marks even when they know the answer?
👉 They likely miss keywords, use vague phrasing, or don’t structure their response.
Q2: How can I help my child give full-scoring answers?
👉 Train them to build full, complete responses by applying the A.B.C answering techniques, with which, they can avoid losing marks due to incomplete or off-target answers.
Q3: What’s a common pitfall in circuit or heat questions?
👉 Students skip over cause-effect explanation. E.g. “The wires snapped” is not enough. The full answer should explain thermal expansion and contraction with context.
Q4: What if my child forgets the correct terms?
👉 We conduct hands-on experiments and activities in our Science class so students retain and apply key terms easily.
🌱 Top Tested PSLE Science Topics 2024 (Overall)
After analysing the 2024 PSLE Science Paper, our academic team identified consistent topic trends. These topics had the highest weightage in 2024 and are likely to remain key areas in future PSLE papers:
So how do we help students go from “almost there” to full marks?
At BlueTree, we use our signature H.U.A.T. & A.B.C. Science Answering Technique, designed specifically for the PSLE. It’s a structured, MOE-aligned framework that helps your child answer with clarity and confidence.
💡 Insight: Over 70% of the PSLE Science paper is made up of these 10 topics—yet most students still struggle due to weak application and answering technique.
⚠️ Common PSLE Science Misconceptions That Cost Marks
It’s not just what your child studies, but how they apply it. Many students lose marks because they:
- Misinterpret graph-based questions (e.g., length vs temperature)
- Use incomplete or vague scientific terms in Open-Ended Questions (OEQ)
- Struggle with cause-and-effect explanations (especially in forces and electrical systems)
- Forget to link back to the question properly
⚡ BONUS: Tackling PSLE Heat Question With Confidence (PSLE/2024/Q36)
The graph shows how the length of wire made of material S changes with temperature.
(a) State the length of the wire at 0 °C. [1]
Answer: 50mm
Comments: Students might make 2 mistakes in this part. They might have stated as 0mm instead of 50mm as the line of the graph starts from the beginning. Students might also not give the right units and lose the mark.
(b) State the increase in the length of the wire when it is heated from 0 °C to 80°C. [1]
Answer: 6mm
Comments: Same as part (a), students might not have given the right units or gave 56mm as the answer even though the question asked for the increase in the length.
Fadil built a model of telephone lines in the day as shown.
During the night, Fadil heard a crack and found that the wires snapped. There was no wind,
and the model was not disturbed by any person or animal.
(c) Explain why the wires snapped at night. [2]
To answer this question, we need to take a look at the diagram and identify a few things
Comment: From the highlighted area, we can see that the wires were pulled and secured tightly to the wooden support during the day, under the sun. As the wires gained heat, they expanded. When the temperature dropped at night, the wires lost heat and tried to contract. However, because they were secured tightly, they couldn’t contract freely, causing them to stretch and eventually snap.
Answer: During the day, the wires had gained heat and expanded before being pulled tightly and secured with screws on the wooden support. During the night, as the surrounding temperature decrease, the wires lose heat and contract. However, as the wires was secured tightly, the wires stretched while trying to contract and snapped.
(d) Using the same type of wires and equipment, suggest how Fadil can build the model
at the same place so that the wires will not snap. [1]
Answer: Fadil can hang the wires loosely to allow the wires to contract at night.
Comment: For part (d), the key idea is to prevent the wires from snapping as they lose heat. To do this, it’s important to ensure the wires are not stretched tightly. This can be achieved by hanging the wires loosely, allowing room for contraction when the temperature drops.
⚡ BONUS: PSLE Science Electromagnet Question (PSLE/2024/Q38)
Mariam set up the circuit in a toy boat as shown. The metal contacts, A and B, touched the magnet but are not fixed to it. The magnet is resting on a wooden support.
When Mariam closed the switch, the plastic captain moved up and down continuously.
(a) Explain why the captain moved up and down. [2]
Looking at the question, we know that there is a circuit. Let us take a look at the circuit.
Comment: Since the iron cylinder is a magnetic material and a conductor of electricity, it will become magnetised and function as an electromagnet when the circuit is closed. There is also a permanent magnet attached to the plastic captain. When both magnets are present, they can repel each other. Additionally, two metal contacts touch the magnet, helping to complete the circuit. With this understanding of the setup, we can now explain why the plastic captain moves up and down in part (a).
Answer: When the switch is closed, electric current will flow through the iron cylinder, which will cause the iron cylinder to be magnetised and turn into an electromagnet. As the iron cylinder is now an electromagnet, the magnet with the plastic captain will repel, causing the plastic captain to move up. However, as the plastic captain moved up, the circuit will become open as the metal contact B no longer touches the magnet. This will cause the iron cylinder to be no longer be an electromagnet as there is no electric current, causing the plastic captain to move down. When the plastic captain moved down, the magnet will touch metal contact B again, closing the circuit and allow electric current to flow again, magnetising the iron cylinder once again to be an electromagnet to repel the magnet. This cycle will continue.
Comment: The important part for the answer is that as there is 2 parts, which is the moving up and the moving down. Students will need to explain both motion and also explain why this will continue.
Mariam played with the toy for a few hours. The captain moved slower than before.
(b) State another change to the movement of the captain. Explain your answer. [2]
Answer: The plastic captain will not move up as high as before. As the battery has been used for a few hours, there is lesser chemical potential energy left of the battery, converting to lesser electrical energy of the electric current magnetising the iron cylinder, causing the iron cylinder to have lesser magnetic strength. This will cause the iron cylinder to exert a smaller repulsion force on the magnet, causing the plastic captain to be repel lesser, which means that there will be lesser height.
Comment: For part (b), 2 important factors will be the magnetic repulsion force and why is there lesser magnetic repulsion force. As the battery has not been replaced, the battery will have lesser power so that means lesser potential energy as well, which in energy conversion means that there will be lesser electrical energy converted, causing the iron cylinder to have lesser magnetic strength, which means lesser repulsion force.
