In the app: https://ai.page/roadmap/or-sci-grade-7 Part of: [Oregon: Science](https://ai.page/roadmap/or-sci.md) Goal: Oregon academic standards: Science, Grade 7 ## 1. Physical Science · Matter and Its Interactions - [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 - [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 - [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 ## 2. Life Science · 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) - [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 ## 3. Life Science · From Molecules to Organisms: Structures and Processes - [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 - [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. Earth & Space Science · Earth and Human Activity - [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 ## 5. Earth & Space Science · Earth's Systems - [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 - [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 - [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 ## Health: 0 of 100 Of its 14 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
