In the app: https://ai.page/roadmap/nc-sci-grade-7 Part of: [North Carolina: Science](https://ai.page/roadmap/nc-sci.md) Goal: North Carolina academic standards: Science, Grade 7 ## 1. Earth and Human Activity · Understand the reciprocal relationship between the atmosphere and humans. - [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 ## 2. Earth’s Systems · Understand the atmosphere and how the cycling of water relates to Earth’s weather and climate. - [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 - [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 ## 3. Heredity- Inheritance and Variation of Traits · Understand the relationship of the mechanisms of reproduction, patterns of inheritance, and potential variation among offspring. - [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 - [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 - [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 ## 4. From Molecules to Organisms- Structures and Processes · Understand the processes, structures and functions of living organisms that enable them to survive, reproduce and carry out the basic functions - [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 - [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 - [Cells Under the Microscope](https://ai.page/c/cells-under-the-microscope/index.md): Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure - [Parts of Plant and Animal Cells](https://ai.page/c/parts-of-plant-and-animal-cells/index.md): Describe the functions of the main components of plant and animal cells: cell wall, cell membrane, cytoplasm, nucleus, vacuole, mitochondria, ribosomes, and chloroplasts - [Single-Celled Organisms](https://ai.page/c/single-celled-organisms/index.md): Explain how unicellular organisms such as bacteria and Amoeba carry out all the functions of life within a single cell ## 5. Energy · Understand forms of energy, energy transfer and transformation, and conservation in mechanical systems. - [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) ## 6. Motion and Stability: Forces and Interactions · Understand motion, the effects of forces on motion, and the graphical representations of motion. - [Relative Motion](https://ai.page/c/relative-motion/index.md): Explain relative motion — how the apparent speed and direction of an object depends on the observer's own motion — using everyday examples such as trains and cars passing - [Resultant Forces](https://ai.page/c/resultant-forces/index.md): Describe forces as vector quantities with both magnitude and direction, distinguish between balanced forces (zero resultant, no change in motion) and unbalanced forces (non-zero resultant, causes acceleration or deceleration) ## Health: 0 of 100 Of its 15 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
