Goal: Base Nacional Comum Curricular (BNCC), Ensino Fundamental: Ciências (Science), 8º ano

## 1. Science

- [Renewable vs non-renewable energy](https://ai.page/c/renewable-vs-non-renewable-energy/index.md): Distinguish between renewable energy resources (solar, wind, hydroelectric, tidal, geothermal, biomass) and non-renewable resources (coal, oil, gas, nuclear), comparing their advantages, disadvantages, and environmental impacts
- [Series vs parallel circuits](https://ai.page/c/series-vs-parallel-circuits/index.md): Describe and apply the rules for current, voltage, and resistance in series and parallel circuits, and explain the practical uses of each circuit type
- [Power: watts and energy per second](https://ai.page/c/power-watts-and-energy-per-second/index.md): Define power as the rate of energy transfer (power = energy ÷ time, measured in watts), and compare energy transfer rates in different everyday contexts
- [Plant Reproduction](https://ai.page/c/plant-reproduction/index.md): Describe the structure of a flower and explain the processes of wind and insect pollination, fertilisation, seed and fruit formation, and seed dispersal in plants
- [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
- [Phases of the Moon](https://ai.page/c/phases-of-the-moon/index.md): Explain the phases of the Moon as the changing angle of sunlight on the lunar surface as seen from Earth, and describe how solar and lunar eclipses occur
- [Why We Have Seasons](https://ai.page/c/why-we-have-seasons/index.md): Explain that the seasons are caused by the tilt of Earth's axis during its orbit around the Sun, distinguishing this from the common misconception that seasons are caused by changing distance from the Sun
