Welcome to P3 Science at ScienceStar!
Primary 3 is where your science journey begins — and it is one of the most exciting stages of all. In P3, you will discover how living things are different from non-living things, learn why plants need sunlight and water, and find out how animals survive in their habitats. You will also explore the fascinating world of materials — why some things are hard, soft, shiny, or waterproof — and discover how light, heat, and magnets work in everyday life.
The Singapore MOE P3 Science syllabus covers eight main themes: Diversity of Living and Non-Living Things, Plants, Animal Life Cycles, Fungi and Bacteria, Materials and Their Properties, Light, Heat, and Magnets. Each topic builds on what you learned before, so understanding P3 well gives you a strong head start for P4 and PSLE Science.
At ScienceStar, we make P3 Science fun and easy to understand. Our quizzes test exactly what your school exams will ask, and our flashcards help you remember key facts fast. Explore the topics below, take a quiz, and earn XP as you learn! Every question you get right brings you one step closer to acing your P3 Science exam.

About the P3 Science Topics
Diversity of Living Things — Students learn to classify living things and non-living things. You will study the five groups of vertebrates and key groups of invertebrates using the MRS GREN framework.
Plant System — Understand the four main parts of a plant (root, stem, leaf, flower) and the process of photosynthesis, where plants use sunlight, water and carbon dioxide to make glucose.
Animal Life Cycles — Explore complete and incomplete metamorphosis. Learn the life cycles of butterflies, frogs, grasshoppers and more with detailed stage comparisons.
Materials & Their Properties — Discover how materials differ in transparency, conductivity, solubility and density, and why we choose different materials for different uses in everyday life.
Light, Heat, and Magnets — Learn how light travels in straight lines, how heat flows from hot to cold objects, and the rules of magnetic attraction and repulsion with the four magnetic materials.
