Sample Yamaguchi Prefectural Public High School Entrance Examination — Science Practice Questions

Try these sample questions to test your Yamaguchi Prefectural Public High School Entrance Examination — Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which unit is used to measure force?
A.Newton (N)
B.Joule (J)
C.Watt (W)
D.Pascal (Pa)
Explanation: Force is measured in newtons (N), where 1 N = 1 kg·m/s².
2A body moves at constant velocity. What can be said about the net force on it?
A.The net force is zero
B.The net force is forward
C.The net force is backward
D.The net force is increasing
Explanation: By Newton's first law (inertia), constant velocity means zero acceleration, so the net force is zero.
3What is the acceleration of gravity near Earth's surface (approximate value)?
A.9.8 m/s²
B.1.0 m/s²
C.98 m/s²
D.0.98 m/s²
Explanation: Gravitational acceleration near Earth's surface is about 9.8 m/s².
4When a force is drawn as an arrow in a diagram, which three properties (力の三要素) must the arrow show?
A.Point of application, direction, and magnitude
B.Mass, direction, and speed
C.Point of application, mass, and time
D.Direction, temperature, and magnitude
Explanation: A force arrow encodes three things: where the force acts (作用点, the tail of the arrow), which way it acts (向き, where the arrow points), and how big it is (大きさ, the length of the arrow). Getting all three right is what makes a force diagram readable.
5A 100 V electric heater draws a current of 5 A. What is its electrical power (電力)?
A.500 W
B.20 W
C.105 W
D.0.05 W
Explanation: Electrical power is voltage × current: P[W] = V[V] × I[A] = 100 × 5 = 500 W. This is the figure printed on Japanese appliance labels as 消費電力.
6Work is calculated as force × distance. If a 5 N force moves an object 4 m in the force's direction, how much work is done?
A.20 J
B.9 J
C.1.25 J
D.45 J
Explanation: Work = F × d = 5 × 4 = 20 J.
7Which type of energy does a stretched rubber band store?
A.Elastic potential energy
B.Kinetic energy
C.Thermal energy
D.Electrical energy
Explanation: A stretched (deformed) elastic object stores elastic potential energy.
8In a series circuit, how does the current compare at every point?
A.The current is the same at every point
B.The current increases along the circuit
C.The current decreases along the circuit
D.The current is zero at the middle

9Ohm's law states V = IR. If a 3 Ω resistor has 2 A flowing through it, what is the voltage across it?
A.6 V
B.1.5 V
C.5 V
D.0.67 V
Explanation: V = IR = 2 × 3 = 6 V.
10Which device converts electrical energy into mechanical (rotational) energy?
A.Electric motor
B.Electric generator
C.Transformer
D.Battery
Explanation: An electric motor uses current in a magnetic field to produce rotation (electrical → mechanical).

About the Yamaguchi Prefectural Public High School Entrance Examination — Science Exam

The Yamaguchi Prefectural Public High School Entrance Examination in Science (理科) tests lower-secondary graduates across physics, chemistry, biology and earth science, with several 大問 including a 総合(融合)問題 that crosses fields, and diverse answer formats. From 2026 (令和8年度) a 特色選抜 replaces the old 推薦選抜 (出願 1/21-1/28, 検査 2/4(水) [or 2/5], 内定通知 2/12; every school holds a 個人面接 and may run a 学校独自検査 such as 総合問題・基礎学力検査・口頭試問・小論文・プレゼン・作文・集団討論・実技検査), alongside the 第一次募集 general selection (出願 2/13-2/24, 学力検査 3/5(木), 合格発表 3/12(木); 面接・小論文・実技検査 may be held at schools that choose them) and a 第二次募集 (3/12発表; 面接必須, 小論文・実技可). A WEB出願 system was introduced in 令和8年度. The general academic test (学力検査) is a prefecture-wide common paper covering five subjects (国語, 数学, 英語, 社会, 理科), each worth 50 points (合計 250点); for 令和8年度 the 第一次募集 学力検査 is sat on a single day, 3月5日(木). The 理科 common paper (14:10-15:00, sat fifth) is balanced across 物理・化学・生物・地学 with a 総合(融合)問題, has several 大問 and diverse answer formats (記号選択, 語句記述, 計算, 作図, 短文記述, 資料読取), and mixes 記号選択 (multiple-choice) with 記述・作図 answers, so it is not a pure multiple-choice paper. Selection combines the 学力検査 total (250) with the 調査書 (中1-3 9教科×5 = 135点) on an equal-treatment basis, with each school setting its own比重 and some applying 傾斜配点 (up to 2× via 学校指定 or 生徒指定). The 全日制 通学区域 is 山口県全域. The paper is aligned to the MEXT junior-high Course of Study (平成29年 中学校学習指導要領 理科編) and tests 知識・技能 plus 思考力・判断力・表現力.

Assessment

50-point paper aligned to the MEXT 理科 Course of Study, covering physics (25%), chemistry (25%), biology (25%) and earth science (25%), with a 総合(融合)問題 that crosses fields. The prefectural common paper mixes 記号選択 items with 語句記述, 計算, 作図, 短文記述 and 資料読取; it has several 大問 and diverse answer formats. The five academic-test subjects each carry 50 points (合計 250点), and 理科 is sat fifth on the single 学力検査 day (令和8年3月5日(木), 14:10-15:00). The paper tests 知識・技能 plus 思考力・判断力・表現力, including reading experimental and observational data and explaining reasons. The Yamaguchi Prefectural Board of Education does not publish per-topic percentage weights for the 理科 paper; the even 25% quarters used here are this bank's own study weighting, derived from the MEXT Course of Study's four-field structure and the recurring 大問 coverage.

Yamaguchi Prefectural Public High School Entrance Examination — Science Study Tips from Top Performers

1Memorise symbols, formulas, and the key facts (e.g. water boils at 100 °C at 1 atm, N₂ is the most abundant atmospheric gas) as reliable early points — 用語一問一答 items are worth securing.
2For 計算 items (Ohm's law, F = ma, mgh, density), write the formula, substitute with units, then solve — most slips are unit or arithmetic errors.
3Practise reading 資料 (graphs, tables, experimental results) carefully: check axes, units and trends before answering, since many sub-questions are 資料読取 and the problem text is long.
4For 生物 and 地学, link structure to function (e.g. mitochondria → respiration, plate boundaries → earthquakes) and be ready to explain reasons in a short sentence.
5Prepare for the 総合(融合)問題 by practising problems that combine fields (e.g. 光 with 蒸留・熱反応), since it carries a larger per-question weight.
6For 作図 and 短文記述, rehearse the standard patterns (force arrows, ray diagrams, one-sentence cause-and-effect) since these are not reproduced in this MCQ bank.

Frequently Asked Questions

Is this question bank the same as the real Yamaguchi 理科 exam?

No. The official paper is balanced across 物理・化学・生物・地学 with several 大問 including a 総合(融合)問題, and diverse answer formats (記号選択, 語句記述, 計算, 作図, 短文記述, 資料読取); its exact item count is not published. This bank is an English-language multiple-choice study adaptation covering physics, chemistry, biology and earth science, each with an explanation; it does not reproduce the 作図 or 記述 answer tasks and cannot replace them.

How long is the Yamaguchi 理科 paper and what is it worth?

It is scored out of 50 points, one of five subjects totalling 250 points (each subject 50 points). 理科 is sat fifth (last) on the single 学力検査 day (令和8年3月5日(木), 14:10-15:00). The 特色選抜 検査日 is 2月4日(水) (or 2月5日(木) for schools that need a second day).

Does the paper include diagrams and short-answer explanations?

Yes. The 理科 paper uses diverse answer formats including 記号選択, 語句記述, 計算, 作図, 短文記述 and 資料読取, with a 総合(融合)問題 that crosses fields. This MCQ bank covers only the conceptual and calculation knowledge behind those tasks; you must practise drawing diagrams and writing short explanatory answers separately.

How is the selection structured?

From 2026 (令和8年度) Yamaguchi runs a 特色選抜 (出願 1/21-1/28, 検査 2/4(水) [or 2/5], 内定通知 2/12; every school holds a 個人面接 and may run a 学校独自検査) and a 第一次募集 general selection (出願 2/13-2/24, 学力検査 3/5(木), 合格発表 3/12(木)), with a 第二次募集 for schools that did not fill. The 第一次募集 combines the 学力検査 total (5 subjects × 50 = 250 points) with the 調査書 (中1-3 9教科×5 = 135点); 山口県教育委員会 states the 調査書の「学習の記録」と学力検査の成績は同等に取り扱う. Each school may apply 傾斜配点 (up to 2× via 学校指定 or 生徒指定 on one or two subjects). Selection is relative to other applicants, not against a published pass line.

How much is the examination fee?

The 入学試験料 (入学検定料) is ¥2,200 for a full-time (全日制) course (¥700 for 定時制); it may be reduced or waived in cases of financial hardship.
