In the app: https://ai.page/roadmap/tn-sci-grade-7 Part of: [Tennessee: Science](https://ai.page/roadmap/tn-sci.md) Goal: Tennessee academic standards: Science, Grade 7 ## 1. Earth and Human Activity - [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. 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 - [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 ## 3. Ecosystems: Interactions, Energy, and Dynamics - [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 ## 4. From Molecules to Organisms: Structures and Processes - [Plant Cells vs Animal Cells](https://ai.page/c/plant-cells-vs-animal-cells/index.md): Compare plant and animal cells, identifying shared features and structures unique to plant cells (cell wall, vacuole, chloroplasts) - [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 - [Human Reproduction](https://ai.page/c/human-reproduction/index.md): Describe the structure and function of the male and female human reproductive systems, and explain the processes of fertilisation, gestation, and birth including the role of the placenta - [How animals adapt to environments](https://ai.page/c/how-animals-adapt-to-environments/index.md): Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time - [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 - [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 ## 5. Matter and Its Interactions - [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 - [Metals vs Non-Metals](https://ai.page/c/metals-vs-non-metals/index.md): Compare the physical and chemical properties of metals and non-metals, explaining metallic properties (malleability, lustre, conductivity) and how position in the periodic table predicts reactivity - [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) - [Pure Substances & Mixtures](https://ai.page/c/pure-substances-and-mixtures/index.md): Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity ## 6. Engineering Design - [Simple Design Problems](https://ai.page/c/simple-design-problems/index.md): Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost ## 7. Energy - [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 - [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 ## Health: 0 of 100 Of its 18 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
