Practice Questions
| Number | Name | Type | Difficulty | Marks | Description |
|---|---|---|---|---|---|
| 1. | Light | Other | easy | 1 m. | This question assesses the basic concept of light as a form of energy and its role in enabling vision and explaining natural and man-made phenomena through straight-line travel and interaction with objects. |
| 2. | Boundaries of Scientific Investigation | Other | easy | 1 m. | This question evaluates the understanding of the principles and boundaries of scientific investigation, including observation, experimentation, and control of variables in everyday contexts. |
| 3. | Calendar | Other | easy | 1 m. | This question emphasizes how ancient civilizations used natural lunar phases and solar cycles to measure time and develop early calendar systems for organizing human activities. |
| 4. | Earth’s Life-Supporting Conditions | Other | medium | 2 m. | This question explores how Earth’s unique conditions enable life and how human activities can impact and disrupt this delicate environmental balance. |
| 5. | Refraction of Light and Applications | Other | medium | 3 m. | This question assesses how the bending of light and its interaction with different media and lenses explain image formation and its applications in vision correction and optical devices. |
