Goal: Kentucky academic standards: Science, Grade 6

## 1. Grade 6

- [Matter Is Made of Particles](https://ai.page/c/matter-is-made-of-particles/index.md): Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases
- [Ocean Ecosystems](https://ai.page/c/ocean-ecosystems/index.md): Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system
- [Oceans & Climate](https://ai.page/c/oceans-and-climate/index.md): Understand the connection between the ocean and climate: the ocean absorbs heat and carbon dioxide, drives weather patterns through evaporation, and ocean currents distribute warmth around the planet — making the ocean Earth's climate engine
- [Sun-Driven Weather Systems](https://ai.page/c/sun-driven-weather-systems/index.md): Understand how the Sun drives weather: the Sun heats Earth's surface unevenly (land heats faster than water, equator gets more heat than poles), creating differences in air pressure that cause wind patterns, ocean currents, and large-scale weather systems
- [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
- [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
- [Energy stores and transfers](https://ai.page/c/energy-stores-and-transfers/index.md): Identify the main energy stores (kinetic, gravitational potential, elastic potential, thermal, chemical, nuclear, electromagnetic) and the pathways by which energy is transferred between stores (mechanically, electrically, by heating, by radiation)
- [Energy can't be created or destroyed](https://ai.page/c/energy-can-t-be-created-or-destroyed/index.md): Explain the principle of conservation of energy (energy cannot be created or destroyed, only transferred between stores), and describe how energy is dissipated as thermal energy to the surroundings in all real processes
- [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
- [How Tectonic Plates Move](https://ai.page/c/how-tectonic-plates-move/index.md): Understand that convection currents in the molten mantle drive the movement of rigid tectonic plates; distinguish between convergent (collision/subduction), divergent (spreading ridges), and transform (sliding) plate boundaries; explain why volcanoes, earthquakes, and mountain chains cluster at boundaries; introduce the Wilson cycle of supercontinent assembly and breakup
- [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
- [Scale of the Solar System](https://ai.page/c/scale-of-the-solar-system/index.md): Use scale models, diagrams, or calculations to represent the relative sizes and distances of objects in the solar system, understanding that the distances between planets are enormously larger than the planets themselves
- [Life Changed Over Time](https://ai.page/c/life-changed-over-time/index.md): Recognise that living things have changed over time and that fossils provide information about organisms that inhabited the Earth millions of years ago
- [Erosion and weathering](https://ai.page/c/erosion-and-weathering/index.md): Make observations and measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation
- [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
- [Atoms, Elements & Compounds](https://ai.page/c/atoms-elements-and-compounds/index.md): Explain the differences between atoms, elements, and compounds; describe the simple Bohr model of the atom (nucleus with protons and neutrons, electrons in shells); and write and interpret chemical symbols and simple formulae
- [Physical vs Chemical Changes](https://ai.page/c/physical-vs-chemical-changes/index.md): Distinguish between physical changes (reversible, no new substances formed) and chemical changes (new substances formed, often irreversible), using conservation of mass to understand both types
- [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
- [The Vast Scale of Space](https://ai.page/c/the-vast-scale-of-space/index.md): Describe the scale of the universe in nested layers: Earth is one planet in our solar system, the Sun is one star among billions in the Milky Way galaxy, and the Milky Way is one galaxy among billions in the universe
- [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
- [Star Brightness & Distance](https://ai.page/c/star-brightness-and-distance/index.md): Support an argument that the apparent brightness of the sun and stars is due to their relative distances from Earth, understanding the sun is a relatively close star
- [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
- [Matter Cycling in Ecosystems](https://ai.page/c/matter-cycling-in-ecosystems/index.md): Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment in an ecosystem
- [Food Webs & Interdependence](https://ai.page/c/food-webs-and-interdependence/index.md): Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others
- [Evidence-Based Classification](https://ai.page/c/evidence-based-classification/index.md): Give reasons for classifying plants and animals based on specific characteristics, using evidence to justify classification decisions
- [Photosynthesis](https://ai.page/c/photosynthesis/index.md): Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots
- [Universal Gravitation](https://ai.page/c/universal-gravitation/index.md): Describe gravity as a universal attractive force between all masses, explain that orbital motion arises because gravity provides the centripetal force keeping objects in orbit, and compare gravitational field strengths on different planets
- [Newton's Third Law](https://ai.page/c/newton-s-third-law/index.md): State and apply Newton's Third Law: every force has an equal and opposite reaction force acting on a different object, distinguishing action-reaction pairs from balanced forces
- [Comparing Possible Solutions](https://ai.page/c/comparing-possible-solutions/index.md): Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints
- [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
- [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
