Grade 7 Science and Technology study guide
Grade 7 Science and Technology · Work through your exam, one topic at a time.
Grade 7 Science and Technology is a junior secondary school subject that introduces students to scientific inquiry, matter and materials, forces and energy, living systems, ecosystems, Earth and space, engineering design, and the relationship between science, technology, society, and the environment. It is aimed at learners around 12–13 years old who are building the observation, measurement, and reasoning skills that support later science study. The Grade 7 Science and Technology study guide has 8 sections and about 2,230 words.
01Scientific Inquiry and Investigation Skills
Scientific Inquiry and Investigation Skills is the domain that asks you to plan fair tests, choose measurements, organize data, and justify conclusions. Exam items typically give a scenario and ask which variable changed, whether the method was valid, or what a graph shows.
313 words, about 2 min02Matter, Materials and Their Properties
Matter, Materials and Their Properties tests particle explanations of states, physical versus chemical changes, characteristic properties, mixtures, separation techniques, and conservation of mass. Questions often ask you to classify a change or choose a method to separate a mixture.
282 words, about 1 min03Forces, Motion and Energy
Forces, Motion and Energy tests net force, balanced and unbalanced forces, speed and motion graphs, friction, and energy transfers. Exam items often ask you to calculate speed or explain why an object speeds up, slows down, or stays still.
281 words, about 1 min04Living Systems: Cells, Body Systems and Health
Living Systems: Cells, Body Systems and Health tests cell structures, levels of organization, organ-system functions, homeostasis, and health choices. Questions often ask how two systems cooperate or which organelle performs a function.
278 words, about 1 min05Ecosystems, Biodiversity and Environmental Science
Ecosystems, Biodiversity and Environmental Science tests food webs, energy flow, nutrient cycles, population interactions, biodiversity, and human impacts. Exam items often ask what happens when one population changes or why food chains are short.
258 words, about 1 min06Earth, Space and Natural Cycles
Earth, Space and Natural Cycles tests Earth systems, rocks and tectonics, weathering and erosion, the water cycle, and explanations for seasons, moon phases, and eclipses. Questions often ask you to choose the correct cause for an everyday sky or landscape observation.
275 words, about 1 min07Engineering Design and Technology Applications
Engineering Design and Technology Applications tests problem definition, criteria and constraints, prototyping, testing, iteration, and trade-offs. Exam items often present a design scenario and ask what should be tested or why a prototype failed.
286 words, about 1 min08Science, Technology, Society and the Environment
Science, Technology, Society and the Environment tests how evidence informs technology and decisions, and how technologies create benefits, risks, and environmental effects. Questions often ask you to evaluate a claim or identify a trade-off.
