- Nutrients and their functions
- Food pyramid

2. Plants:
- Parts of a plant: roots, stem, leaves, flowers, and fruits
- Types of plants: flowering and non-flowering
- Photosynthesis and its importance
- Plant life cycle: germination, growth, and reproduction
- Uses of plants

3. Animals:
- Classification of animals: vertebrates and invertebrates
- Body coverings: fur, feathers, scales, and skin
- Habitats and adaptations of animals
- Life cycles of animals: birth, growth, reproduction, and death
- Animal food habits: herbivores, carnivores, and omnivores

4. Human Body:
- Sense organs and their functions

Science Olympiad: Sample Paper 2018 (Set A)
The Science Olympiad is a competitive examination that tests students' knowledge and understanding of scientific concepts. The sample paper for the Science Olympiad 2018 (Set A) is designed to assess students' comprehension and problem-solving skills in various science topics. Although the specific questions in the sample paper may vary, here is a general overview of the areas covered:

1. Multiple-choice questions on various science topics, including:
- Biology: plants, animals, human body, and environment
- Chemistry: materials, changes, and reactions
- Physics: energy, forces, and motion

2. Diagram-based questions that require the identification and labeling of different scientific phenomena, such as parts of a plant or the human digestive system.

3. Practical-based questions that test students' ability to apply scientific concepts to real-life scenarios, such as identifying the best safety measures in different situations or suggesting ways to conserve natural resources.

4. Problem-solving questions that require critical thinking and analysis of scientific principles, such as determining the cause and effect of a given situation or predicting the outcome of a scientific experiment.

It is important for students to thoroughly understand the concepts covered in the Class 4 science syllabus to perform well in the Science Olympiad. Regular practice, revision, and solving sample papers can greatly enhance students' chances of success in the Olympiad.
