Grade 8 - [Climate Change Basics](https://ai.page/c/climate-change-basics/index.md): Understand the basics of climate change: Earth’s atmosphere traps some of the Sun's heat (the greenhouse effect), burning fossil fuels adds extra greenhouse gases (especially CO₂), this is making Earth gradually warmer, and this warming changes weather patterns, melts ice, and raises sea levels - [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 - [Tables, charts, and graphs](https://ai.page/c/tables-charts-and-graphs/index.md): Construct data tables with correct headings and SI units, plot appropriate graph types (bar chart, line graph, scatter graph), draw a line of best fit, and calculate the gradient of a straight-line graph - [Drawing conclusions from evidence (age 12+)](https://ai.page/c/drawing-conclusions-from-evidence-age-12/index.md): Identify patterns and trends in data, draw conclusions that directly address the hypothesis with quantitative reference to evidence, and evaluate the investigation by distinguishing between systematic and random errors and proposing targeted improvements - [Biodiversity & Resilience](https://ai.page/c/biodiversity-and-resilience/index.md): Explain what biodiversity means, why high biodiversity makes ecosystems more resilient, and describe the ways human activity threatens biodiversity (habitat destruction, pollution, invasive species, climate change) - [Hazard Assessment & Evacuation](https://ai.page/c/hazard-assessment-and-evacuation/index.md): Explain probabilistic hazard assessment using eruption recurrence intervals and fault slip rates; describe how volcano observatories monitor ground deformation, gas emissions, and seismicity to issue alert levels; explore why communities remain near active hazards (fertile volcanic soil, poverty, cultural ties); discuss the ethics and politics of evacuation decisions and the social justice dimensions of disaster risk - [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 - [Chromosomes, Genes & DNA](https://ai.page/c/chromosomes-genes-and-dna/index.md): Describe the relationship between chromosomes, genes, and DNA in heredity, including the double helix structure of DNA and the historical roles of Watson, Crick, Franklin, and Wilkins - [Variation in Species](https://ai.page/c/variation-in-species/index.md): Explain variation within and between species, distinguishing between continuous variation (e.g. height) and discontinuous variation (e.g. blood group), and between genetic and environmental causes - [Genetic Mutation](https://ai.page/c/genetic-mutation/index.md): Explain genetic mutation as a random change in DNA sequence, describe causes of mutation (e.g. radiation, chemicals, copying errors), and explain that most mutations are neutral, some harmful, and a few beneficial - [How Natural Selection Works](https://ai.page/c/how-natural-selection-works/index.md): Explain natural selection as the mechanism of evolution: heritable variation + competition for resources + differential survival and reproduction = change in allele frequency over generations - [Evidence for Evolution](https://ai.page/c/evidence-for-evolution/index.md): Describe the main types of evidence for evolution: the fossil record (change over time), comparative anatomy (homologous structures), and the geographic distribution of related species - [Fossils as Evidence](https://ai.page/c/fossils-as-evidence/index.md): Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago - [Human Reproduction](https://ai.page/c/human-reproduction/index.md): Describe the structure and function of the male and female human reproductive systems, and explain the processes of fertilisation, gestation, and birth including the role of the placenta - [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 - [Types of Chemical Reaction](https://ai.page/c/types-of-chemical-reaction/index.md): Identify and describe four types of chemical reaction: combustion (burning in oxygen), oxidation (gain of oxygen), thermal decomposition (breaking down by heat), and displacement (more reactive metal replaces less reactive one) - [Pure Substances & Mixtures](https://ai.page/c/pure-substances-and-mixtures/index.md): Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity ## Health: 0 of 100 Of its 17 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
