Grade 7 - [Senses, Brain & Responses](https://ai.page/c/senses-brain-and-responses/index.md): Use a model to describe that animals receive information through their senses, process it in their brain, and respond in different ways - [Drawing conclusions from evidence (age 9+)](https://ai.page/c/drawing-conclusions-from-evidence-age-9/index.md): Report and present findings including conclusions, causal relationships, explanations, and a degree of trust in results using oral and written forms - [Tables, charts, and graphs](https://ai.page/c/tables-charts-and-graphs/index.md): Construct data tables with correct headings and SI units, plot appropriate graph types (bar chart, line graph, scatter graph), draw a line of best fit, and calculate the gradient of a straight-line graph - [Drawing conclusions from evidence (age 12+)](https://ai.page/c/drawing-conclusions-from-evidence-age-12/index.md): Identify patterns and trends in data, draw conclusions that directly address the hypothesis with quantitative reference to evidence, and evaluate the investigation by distinguishing between systematic and random errors and proposing targeted improvements - [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) - [Aerobic Respiration](https://ai.page/c/aerobic-respiration/index.md): Explain aerobic respiration as the process by which organisms release energy from glucose using oxygen, producing carbon dioxide and water; write and interpret the word equation: glucose + oxygen → carbon dioxide + water - [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 - [Wave Properties & Types](https://ai.page/c/wave-properties-and-types/index.md): Describe waves in terms of amplitude, wavelength, frequency, and wave speed; distinguish transverse waves (oscillation perpendicular to direction of travel) from longitudinal waves (oscillation parallel); and use the wave equation v = fλ - [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 - [Writing Science Reports](https://ai.page/c/writing-science-reports/index.md): Communicate scientific findings in a structured report using appropriate scientific vocabulary, SI units, and standard notation; describe how peer review and replication contribute to the reliability of scientific knowledge - [How Sound Waves Travel](https://ai.page/c/how-sound-waves-travel/index.md): Explain that sound is produced by vibrating objects and travels as a longitudinal pressure wave through solids, liquids, and gases; describe reflection of sound (echoes) and absorption; explain why sound cannot travel through a vacuum - [Speed and energy](https://ai.page/c/speed-and-energy/index.md): Use evidence to construct an explanation relating the speed of an object to the energy of that object - [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) - [Energy can't be created or destroyed](https://ai.page/c/energy-can-t-be-created-or-destroyed/index.md): Explain the principle of conservation of energy (energy cannot be created or destroyed, only transferred between stores), and describe how energy is dissipated as thermal energy to the surroundings in all real processes - [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 - [Conduction, convection, and radiation](https://ai.page/c/conduction-convection-and-radiation/index.md): Describe and compare the three mechanisms of heat transfer — conduction (particle vibration through solids), convection (fluid movement in liquids/gases), and radiation (infrared waves) — and explain that the rate of transfer depends on temperature difference - [Power: watts and energy per second](https://ai.page/c/power-watts-and-energy-per-second/index.md): Define power as the rate of energy transfer (power = energy ÷ time, measured in watts), and compare energy transfer rates in different everyday contexts - [Controlling variables](https://ai.page/c/controlling-variables/index.md): Plan different types of scientific enquiries to answer questions, recognising and controlling variables where necessary - [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 - [Comparing Possible Solutions](https://ai.page/c/comparing-possible-solutions/index.md): Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints - [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) - [Gravity & Falling Objects](https://ai.page/c/gravity-and-falling-objects/index.md): Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object - [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 - [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 - [Types of Chemical Reaction](https://ai.page/c/types-of-chemical-reaction/index.md): Identify and describe four types of chemical reaction: combustion (burning in oxygen), oxidation (gain of oxygen), thermal decomposition (breaking down by heat), and displacement (more reactive metal replaces less reactive one) - [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 ## Health: 0 of 100 Of its 29 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
