In the recent PSLE examinations, an intriguing shift has surfaced, placing greater emphasis on ‘definition’ questions. These questions often require students to ‘state’ or ‘describe’ scientific processes or terms, such as ‘digestion’.
To help your child secure top marks in PSLE Science, it is crucial to equip them with the skills to tackle these definition questions effectively. By mastering precise scientific keywords, your child can ensure they score the maximum marks for such questions.
Unveiling the Power of Science Keywords
To prepare your child comprehensively for the PSLE Science exams, we’ve meticulously compiled a list of processes and terms that have been frequently tested in previous years. Familiarizing your child with these topics and their associated keywords will not only enhance their understanding of scientific concepts but also better prepare them to handle similar questions in the future.
PSLE Science Definition: Life Science
1. What is Pollination?

Pollination is the intricate process of transferring pollen grains from the anthers of a male flower of a plant to the stigma of a female flower of the same species. This vital process facilitates the reproduction of flowering plants.
2. How does Photosynthesis work in Plants?

Photosynthesis is the remarkable natural phenomenon in which plants utilize specialized cellular structures called chloroplasts to capture light energy. Through a series of complex chemical reactions, plants convert water and carbon dioxide into oxygen and glucose, a form of sugar that serves as a vital source of energy and nourishment for the plant.
3. What’s the Role of the Circulatory System?

The circulatory system, also known as the cardiovascular system, serves a critical function in the human body. Its primary role is to transport essential substances, including oxygen and nutrients, to every cell in the body while simultaneously removing waste products like carbon dioxide. This intricate network is maintained through the circulation of blood, which carries out this essential task.
4. Deforestation: A Concern for Our Environment
Deforestation is a global environmental concern, where vast tracts of forests are systematically cleared by human activities, often for purposes like agriculture, urbanization, or the production of raw materials. The consequences of deforestation include loss of biodiversity, disruption of ecosystems, and an increase in greenhouse gas emissions.
5. Understanding Digestion

Digestion is the intricate biological process through which the food we consume is broken down into simpler substances that the body can absorb and utilize. It involves a series of chemical and mechanical processes that occur in the digestive system, allowing us to extract essential nutrients and energy from the food we eat.

Boiling is the phase transition in which a liquid, when heated, reaches a specific temperature known as its boiling point. At this point, the liquid transforms into a gas, making it an important concept in thermodynamics and heat transfer.
2. Exploring Evaporation
Evaporation is the process by which a liquid, regardless of its temperature, gradually changes into a gaseous state. This transformation occurs at the surface of the liquid as its molecules gain sufficient energy to break free from the liquid phase.
3. Boiling vs. Evaporation: Distinguishing Characteristics
One key distinction between boiling and evaporation lies in the temperature at which they occur. Boiling transpires at a fixed temperature, whereas evaporation can take place at any temperature, including room temperature.
4. Grasping Temperature

Temperature is a fundamental measure of the thermal energy of a substance. It determines how hot or cold an object or environment is, and it is measured using various scales, such as Celsius or Fahrenheit.
The Path to Academic Excellence
By immersing themselves in the exploration of these scientific keywords, your child will not only enhance their scientific knowledge but also bolster their confidence in tackling ‘definition’ questions in the PSLE Science exam. Encourage them to study and understand these terms comprehensively, as a strong grasp of the right keywords is the key to scoring maximum marks in this challenging section of the examination.
Nurturing this understanding of science will undoubtedly set them on a path to academic excellence and scientific literacy.
