Yamaguchi Prefectural Public High School Entrance Examination - Science · Work through your exam, one topic at a time.
The Yamaguchi Prefectural Public High School Entrance Examination in Science (山口県公立高等学校入学者選抜 理科) is the science component of the prefectural admission selection used by public high schools in Yamaguchi Prefecture for applicants completing compulsory education. It is taken mainly by third-year junior high school students in Yamaguchi, and also by applicants such as those returning from abroad or transferring, who follow the prefecture's published eligibility rules. The Yamaguchi Prefectural Public High School Entrance Examination - Science study guide has 9 sections and about 2,831 words.
01Physics: Motion and Forces
Motion and forces (運動と力) rarely appear as pure definitions in the Yamaguchi paper. They arrive as a recorded experiment - a trolley pulled by a rubber band, or a tape from a 記録タイマー - and you must read the motion off the tape and then explain it with force arrows.
358 words, about 2 min02Physics: Energy, Work, and Electricity
Energy questions combine a work calculation with a circuit or a heating experiment, so the units must be automatic. 仕事 (J) = force (N) × distance moved in the direction of the force (m).
324 words, about 2 min03Chemistry: Substances and Chemical Changes
Substance questions test whether you can classify matter, then describe a change with the precise vocabulary of 化学変化 rather than everyday words. A 純物質 has a fixed 融点 and 沸点; a 混合物 melts and boils over a range.
307 words, about 2 min04Chemistry: Atoms, Molecules, and Chemical Equations
Formula and equation items are easy marks, but only if your atom counting is disciplined. 原子 is the smallest particle of an element; 分子 is a group of atoms bonded together; イオン is an atom or group that has gained or lost electrons.
307 words, about 2 min05Biology: Living Things and Their Environments
Ecology items use a food web or a pond survey and ask you to trace matter and energy, or to predict what happens when one link changes. 生産者 (plants, algae) fix light energy by 光合成; 消費者 pass it on; 分解者 (bacteria, fungi) break down dead matter and return inorganic nutrients to the soil.
307 words, about 2 min06Biology: Structure and Function of the Human Body
Human body questions are diagram-driven, but every diagram reduces to one idea: structure matches function. だ液アミラーゼ: デンプン → 麦芽糖, fastest near 37 °C, inactivated by boiling.
301 words, about 2 min07Earth Science: Earth and the Universe
Earth and space items divide roughly evenly between 天体 (the Sun, stars, moon, solar system) and 大地 (strata, fossils, earthquakes). 自転 runs west → east once a day, which makes celestial objects move east → west at 15° per hour.
301 words, about 2 min08Earth Science: Weather and the Environment
Weather questions ask you to read a 天気図 or a table of 飽和水蒸気量 and then explain the result with air movement. 露点 is the temperature at which the air's water vapour equals the saturation value.
295 words, about 1 min09Scientific Inquiry, Observation, and Experimentation
Inquiry items test the design of an experiment rather than recall of a result: why a control was needed, what was varied, and whether the conclusion follows from the data. 独立変数 is what you change, 従属変数 is what you measure, and 制御変数 are held constant.
