Goal: NCERT Learning Outcomes at the Elementary Stage (2017): Science, Classes 6–8, Class 7

## 1. Science

- [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
- [Waves & Different Materials](https://ai.page/c/waves-and-different-materials/index.md): Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight, communication technologies, and the effects of different surfaces on wave behaviour
- [The Water Cycle](https://ai.page/c/the-water-cycle/index.md): Describe the water cycle, tracing water through evaporation, condensation, precipitation, surface runoff, and transpiration in plants, explaining how the sun drives the cycle
- [Conduction, convection, and radiation](https://ai.page/c/conduction-convection-and-radiation/index.md): Describe and compare the three mechanisms of heat transfer — conduction (particle vibration through solids), convection (fluid movement in liquids/gases), and radiation (infrared waves) — and explain that the rate of transfer depends on temperature difference
- [Acid Reactions & Salts](https://ai.page/c/acid-reactions-and-salts/index.md): Describe and write word equations for the reactions of acids with metals, alkalis (neutralisation), and metal oxides/hydroxides, identifying the salt produced in each case
- [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
- [Cells Under the Microscope](https://ai.page/c/cells-under-the-microscope/index.md): Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure
- [Protecting the Ocean](https://ai.page/c/protecting-the-ocean/index.md): Understand how people protect the ocean: marine protected areas limit fishing and pollution, sustainable fishing prevents overharvesting, beach clean-ups reduce plastic, and international agreements aim to reduce carbon emissions that cause ocean acidification
