Navigating the Paper: A Section-by-Section Breakdown
Section A: Multiple Choice Questions
This section, the first hurdle in the PSLE Science paper, tested students’ ability to comprehend scientific concepts and apply them to specific scenarios. It involved a mix of straightforward questions and those that demanded critical thinking and analytical skills. Let’s explore some key questions and their answers:
- Question 1: Which of the following is a characteristic of living things?
- Answer: (A) They need food.
- Explanation: This question delved into the fundamental characteristics of living organisms. While all options might seem relevant, the need for food is a defining trait of all living things, as it provides energy for growth and survival.
- Question 5: Which of the following is a good conductor of heat?
- Answer: (D) Metal
- Explanation: This question explored the concept of heat transfer. Metals are known for their efficient conduction of heat, evident in our everyday experiences like cooking using metal pans or feeling the warmth of a metal spoon submerged in hot water.
- Question 10: Which of the following is a renewable source of energy?
- Answer: (B) Solar energy
- Explanation: This question touched upon the importance of sustainable energy sources. Solar energy is renewable as it is derived from the sun, an inexhaustible source of energy. The concept of renewable resources is essential for understanding our impact on the environment.
Section B: Open-Ended Questions
Section B presented a more complex challenge, requiring students to apply their knowledge and analytical skills to solve real-world problems. It demanded a deeper understanding of concepts, drawing upon their ability to interpret data, draw conclusions, and communicate scientific reasoning.
- Question 11: A student conducted an experiment to investigate the effect of different types of soil on plant growth.
- Answer: (a) The student should use the same type of plant for all the pots. (b) The student should water all the plants with the same amount of water. (c) The student should place all the pots in the same location. (d) The student should observe the growth of the plants for the same period of time.
- Explanation: This question emphasized the importance of controlled experiments in science. By standardizing factors like plant type, watering, location, and observation time, the student can isolate the effect of soil type on plant growth, ensuring accurate and reliable results.
- Question 15: A simple circuit is set up with a battery, a bulb, and a switch. Explain how the circuit works when the switch is closed.
- Answer: When the switch is closed, the circuit is complete. This allows the electric current to flow from the battery, through the bulb, and back to the battery, causing the bulb to light up.
- Explanation: The answer demonstrates understanding of the fundamental principles of a simple circuit. A complete circuit allows the flow of current, leading to a functional device (in this case, the bulb). This understanding is crucial for comprehending the workings of various electrical appliances we use daily.
- Question 19: Explain why it is important to conserve water.
- Answer: Water is essential for all living things, including humans, animals, and plants. We need water for drinking, growing food, and maintaining a healthy environment. Conserving water helps to ensure that there is enough water for everyone and to protect our resources.
- Explanation: This question addressed a pressing global issue – water scarcity. Students were expected to articulate the dependence of life on water and its role in sustaining ecosystems. Understanding the importance of conservation promotes responsible water usage, a crucial step towards a sustainable future.
