Goal: National Curriculum Framework for School Education 2023 (NCERT): Science, curricular goals and competencies, Middle Stage (Classes 6–8)

## 1. Middle Stage (Classes 6–8)

- [Advanced Material Properties](https://ai.page/c/advanced-material-properties/index.md): Compare and group everyday materials based on advanced properties: hardness, solubility, transparency, electrical and thermal conductivity, and response to magnets
- [How Materials Change State](https://ai.page/c/how-materials-change-state/index.md): Explain melting, freezing, boiling, condensing, and sublimation using the particle model, interpreting heating and cooling curves to identify melting and boiling points
- [Reading Distance-Time Graphs](https://ai.page/c/reading-distance-time-graphs/index.md): Read and plot distance-time graphs for moving objects; interpret the gradient (steepness) of a line as speed; identify stationary periods (horizontal sections), constant speed (straight diagonal lines), and relative speeds by comparing gradients; calculate average speed from the gradient of a straight-line segment using speed = distance ÷ time
- [Magnetic Fields](https://ai.page/c/magnetic-fields/index.md): Describe magnetic poles (north and south), explain attraction and repulsion between poles, describe magnetic field lines plotted using a compass, and explain the Earth's magnetic field and its practical uses
- [Reflection & Refraction](https://ai.page/c/reflection-and-refraction/index.md): State the law of reflection (angle of incidence = angle of reflection) and explain refraction as the change in speed and direction when light crosses a boundary between two media; apply ray diagrams for plane mirrors and refracting surfaces
- [The solar system (age 11+)](https://ai.page/c/the-solar-system-age-11/index.md): Describe the detailed structure of the solar system, including moons, asteroids, and comets, compare orbital periods and distances of the planets, and distinguish between planets, dwarf planets, and other bodies
- [Classifying Organisms](https://ai.page/c/classifying-organisms/index.md): Describe how living things are classified into broad groups (micro-organisms, plants, animals) according to common observable characteristics, similarities, and differences
- [Growing Up & Puberty](https://ai.page/c/growing-up-and-puberty/index.md): Describe the stages of human development from birth to old age: baby, toddler, child, adolescent (puberty), young adult, middle-aged adult, elderly — understanding the physical changes that happen at each stage, especially during puberty
- [Drawing conclusions from evidence (age 9+)](https://ai.page/c/drawing-conclusions-from-evidence-age-9/index.md): Report and present findings including conclusions, causal relationships, explanations, and a degree of trust in results using oral and written forms
