Part of: [Arizona: Science](https://ai.page/roadmap/az-sci.md)

Goal: Arizona academic standards: Science, High school

## 1. DEMONSTRATE CONCEPTS OF ANIMAL MANAGEMENT

- [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

## 2. ANALYZE ANIMAL SCIENCE PRINCIPLES

- [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
- [Grouping Species Using DNA](https://ai.page/c/grouping-species-using-dna/index.md): Explain cladistics: organisms are grouped by shared derived characters, not just similarity; how phylogenetic trees are built using molecular data (DNA sequence alignment) and the molecular clock; explain why birds are technically a group within dinosaurs (crown Avemetatarsalia); distinguish convergent evolution (unrelated species evolving similar traits) from parallel evolution; introduce horizontal gene transfer and why the tree of life is more accurately a web; explain why classification systems keep changing as new data emerge

## 3. ANALYZE PLANT SCIENCE PRINCIPLES

- [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
- [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

## 4. EXAMINE CELL BIOLOGY, STRUCTURES, AND PROCESSES

- [How Diffusion Works](https://ai.page/c/how-diffusion-works/index.md): Explain diffusion as the net movement of particles from a region of higher concentration to lower concentration, and describe its role in moving materials (oxygen, carbon dioxide, glucose) in and between cells
- [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

## 5. EXAMINE THE RELATIONSHIP OF THE ENVIRONMENT TO AGRICULTURE PRODUCTION AND SUSTAINABILITY

- [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

## 6. Geography · Human-environment interactions are essential aspects of human life in all societies.

- [Species Distribution & Change](https://ai.page/c/species-distribution-and-change/index.md): Explain how environmental change (climate change, habitat loss, pollution) affects the distribution of species, including range shifts, local extinction, and invasive species

## 7. Geography · Examining human population and movement helps individuals understand past, present, and future conditions on Earth’s surface.

- [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

## 8. High School Life Sciences

- [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)
- [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
- [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
- [How the Body Stays in Balance](https://ai.page/c/how-the-body-stays-in-balance/index.md): Explain homeostasis as the process of maintaining a stable internal environment; describe the main feedback loop systems (negative feedback) using blood glucose regulation (insulin/glucagon) and body temperature as concrete examples; and connect the endocrine system (hormone-secreting glands) to the nervous system as two complementary communication systems with different speeds and durations

## 9. High School Earth and Space Sciences

- [Galaxies and the universe](https://ai.page/c/galaxies-and-the-universe/index.md): Describe the scale of the universe, including the structure of galaxies, the position of the Sun in the Milky Way, and the use of light years as a unit of distance, and appreciate why space exploration requires enormous timescales
- [Mass vs Weight](https://ai.page/c/mass-vs-weight/index.md): Distinguish between mass (amount of matter, measured in kg) and weight (gravitational force, measured in N), use the equation weight = mass × gravitational field strength, and explain why g differs on other planets and stars
- [Life Cycle of a Star](https://ai.page/c/life-cycle-of-a-star/index.md): Describe the life cycle of a star from nebula through main sequence to its end state (white dwarf, neutron star, or black hole depending on mass), and relate the life cycle to the origin of elements heavier than hydrogen

## 10. High School Physics

- [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
- [Investigating Forces](https://ai.page/c/investigating-forces/index.md): Plan and carry out investigations into forces, including measuring force with a newton meter, investigating Hooke's Law, and collecting and interpreting motion data to test Newton's laws
- [Electromagnets](https://ai.page/c/electromagnets/index.md): Describe the magnetic effect of an electric current (a current-carrying wire produces a magnetic field), and investigate how the strength of an electromagnet depends on current, number of coil turns, and core material

## 11. High School Chemistry

- [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
