In the app: https://ai.page/roadmap/ut-sci-grade-7 Part of: [Utah: Science](https://ai.page/roadmap/ut-sci.md) Goal: Utah academic standards: Science, Grade 7 ## 1. Changes in Species Over Time - [Life Changed Over Time](https://ai.page/c/life-changed-over-time/index.md): Recognise that living things have changed over time and that fossils provide information about organisms that inhabited the Earth millions of years ago - [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 ## 2. Reproduction and Inheritance - [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 - [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 - [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 ## 3. Structure and Function of Life - [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 ## 4. Changes to Earth Over Time - [How fossils form](https://ai.page/c/how-fossils-form-2/index.md): Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time - [How Tectonic Plates Move](https://ai.page/c/how-tectonic-plates-move/index.md): Understand that convection currents in the molten mantle drive the movement of rigid tectonic plates; distinguish between convergent (collision/subduction), divergent (spreading ridges), and transform (sliding) plate boundaries; explain why volcanoes, earthquakes, and mountain chains cluster at boundaries; introduce the Wilson cycle of supercontinent assembly and breakup - [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 - [Natural Disaster Solutions](https://ai.page/c/natural-disaster-solutions/index.md): Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans, such as earthquakes, floods, or volcanic eruptions - [The Rock Cycle](https://ai.page/c/the-rock-cycle/index.md): Explain the rock cycle: how igneous rocks form from magma, sedimentary rocks from compressed sediment, and metamorphic rocks from heat and pressure, and how all rock types can transform into one another over geological time ## 5. Forces are Interactions Between Matter - [Universal Gravitation](https://ai.page/c/universal-gravitation/index.md): Describe gravity as a universal attractive force between all masses, explain that orbital motion arises because gravity provides the centripetal force keeping objects in orbit, and compare gravitational field strengths on different planets - [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 - [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) - [Newton's Third Law](https://ai.page/c/newton-s-third-law/index.md): State and apply Newton's Third Law: every force has an equal and opposite reaction force acting on a different object, distinguishing action-reaction pairs from balanced forces - [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 ## 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.
