Osaka Public High School Entrance Examination - Science study guide
Osaka Public High School Entrance Examination - Science · Work through your exam, one topic at a time.
The Osaka Public High School Entrance Examination science section is the science component of the admission selection used by Osaka Prefecture's public (prefectural and municipal) high schools. Candidates are usually students completing compulsory education who are applying for first-year entry, though the examination also serves other applicant categories. The section is set and administered by the Osaka Prefectural Board of Education; this page is an independent study guide and has no affiliation with that body. Content follows Japan's national curriculum guidelines and is divided into four fields: physics (motion and forces, energy, waves, electricity and magnetism), chemistry (substances and their changes, chemical reactions, particles and atoms), biology (life processes, heredity, organisms and environments), and earth science (the Earth and its surroundings, weather, strata, celestial bodies). The Osaka Public High School Entrance Examination - Science study guide has 4 sections and about 1,248 words.
01Physics: Motion, Forces, Energy, Waves, and Electricity
Physics questions reward one habit: describe the situation precisely before calculating. Distinguish speed (magnitude only) from velocity (magnitude with direction), and read graphs by slope - a distance–time slope is speed, a velocity–time slope is acceleration, and the area under a velocity–time graph is the distance travelled.

First classify: a pure substance has a fixed composition (an element or a compound), while a mixture can be separated without breaking chemical bonds. Filtering removes an insoluble solid, distillation or evaporation separates a solvent from a dissolved solid, recrystallization purifies a solid, and chromatography separates dyes by differing solubility.
303 words, about 2 min03Biology: Life Processes, Environments, and Heredity
Know the cell as the unit of life: nucleus (hereditary information), cytoplasm, cell membrane, and - in plant cells - cell wall, chloroplast, and vacuole. Photosynthesis makes glucose and oxygen from carbon dioxide and water using light, while respiration releases energy from glucose and oxygen and occurs day and night in every living cell.
289 words, about 1 min04Earth Science: Earth, Weather, Strata, and Celestial Bodies
The Earth is layered: crust, mantle, outer core, inner core. The crust is broken into plates whose motion causes earthquakes and volcanoes.
