Goal: Louisiana academic standards: Science, Grade 7

## 1. Life Science

- [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
- [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
- [Digestion & Enzymes](https://ai.page/c/digestion-and-enzymes/index.md): Describe the organs of the human digestive system and how food is physically and chemically digested, including the role of enzymes as biological catalysts
- [The Carbon Cycle](https://ai.page/c/the-carbon-cycle/index.md): Describe the carbon cycle, tracing carbon through photosynthesis, respiration, feeding, decomposition, and combustion, and explain the role of each process
- [Cells to Organ Systems](https://ai.page/c/cells-to-organ-systems/index.md): Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism

## 2. Earth and Space Science

- [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
- [Earth's Atmosphere & CO2](https://ai.page/c/earth-s-atmosphere-and-co2/index.md): Describe the composition of Earth's atmosphere (mainly nitrogen and oxygen, with small amounts of CO₂ and other gases), explain how human activity increases CO₂, and describe the impact on global climate
- [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

## 3. Physical Science

- [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)
- [Conservation of Mass](https://ai.page/c/conservation-of-mass/index.md): Measure and provide evidence that the total weight of matter is conserved regardless of the type of change (heating, cooling, or mixing)
- [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
- [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

## 4. BIOLOGICAL EVOLUTION: UNITY AND DIVERSITY

- [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
- [Offspring resemble parents](https://ai.page/c/offspring-resemble-parents/index.md): Observe that young plants and animals resemble their parents but are not identical, recognising inherited similarities and individual differences

## 5. HEREDITY: INHERITANCE AND VARIATION OF TRAITS

- [Predicting Inherited Traits](https://ai.page/c/predicting-inherited-traits/index.md): Explain how alleles are inherited in sexual reproduction and use Punnett squares to predict the probability of offspring inheriting a characteristic, including dominant and recessive alleles

## 6. ECOSYSTEMS: INTERACTIONS, ENERGY, AND DYNAMICS

- [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
- [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)

## 7. FROM MOLECULES TO ORGANISMS: STRUCTURES AND PROCESSES

- [Energy from Food & the Sun](https://ai.page/c/energy-from-food-and-the-sun/index.md): Use models to describe that energy in animals' food was once energy from the sun, transferred through plants or other organisms
- [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

## 8. EARTH’S SYSTEMS

- [Communities Protecting Resources](https://ai.page/c/communities-protecting-resources/index.md): Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment
- [Earth's atmosphere](https://ai.page/c/earth-s-atmosphere/index.md): Develop a model to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact as connected Earth systems

## 9. ENERGY

- [Reactions That Release or Absorb Heat](https://ai.page/c/reactions-that-release-or-absorb-heat/index.md): Distinguish between exothermic reactions (release energy, temperature rises) and endothermic reactions (absorb energy, temperature falls), with everyday and industrial examples

## 10. MATTER AND ITS INTERACTIONS

- [Drawing Particle Diagrams](https://ai.page/c/drawing-particle-diagrams/index.md): Draw and interpret particle diagrams — dot representations showing the arrangement, spacing, and movement of particles in solids (close, regular, vibrating in place), liquids (close, random, flowing past each other), and gases (widely spaced, moving rapidly in all directions) — and use these diagrams to explain observable properties such as fixed shape, fixed volume, and compressibility
