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

Try these sample questions to test your Yamagata 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.

1A book rests on a desk without moving. Which pair of forces are balanced (力のつり合い) on the book?
A.The weight of the book acting downward and the normal force from the desk acting upward
B.The weight of the book and the force the book exerts on the desk
C.The weight of the book and the weight of the desk
D.The normal force from the desk and friction along the desk surface
Explanation: Two forces are balanced when they act on the same object, are equal in size, opposite in direction, and along the same straight line. The book's weight pulls it down and the desk pushes it up with an equal normal force, so the book stays still.
2What is the SI unit of force?
A.Newton (N)
B.Joule (J)
C.Watt (W)
D.Pascal (Pa)
Explanation: The SI unit of force is the newton (N), defined as 1 N = 1 kg·m/s². Joule is energy, Watt is power, Pascal is pressure.
3A body moves at constant velocity. What can be said about the net force on it?
A.The net force is zero (Newton's first law).
B.The net force is in the direction of motion.
C.The net force opposes the motion.
D.The net force is constant but non-zero.
Explanation: By Newton's first law (inertia), an object at constant velocity has zero net force: all forces balance. Non-zero net force would cause acceleration.
4A box is pulled 3 m along the floor by a steady horizontal force of 20 N in the direction of motion. How much work is done?
A.60 J
B.6.7 J
C.23 J
D.60 W
Explanation: Work equals the force multiplied by the distance moved in the direction of the force: 20 N × 3 m = 60 J. The joule (J) is the unit of work and energy.
5Which law states that for every action there is an equal and opposite reaction?
A.Newton's third law
B.Newton's first law
C.Newton's second law
D.Hooke's law
Explanation: Newton's third law states that forces come in equal and opposite pairs (action–reaction). The first law is inertia; the second is F = ma.
6What is the speed of a car that travels 120 km in 2 hours?
A.60 km/h
B.240 km/h
C.30 km/h
D.120 km/h
Explanation: Speed = distance/time = 120 km / 2 h = 60 km/h.
7A 3 kg object is lifted 2 m (g = 9.8 m/s²). What is the gain in gravitational potential energy?
A.Approximately 58.8 J
B.6 J
C.29.4 J
D.19.6 J
Explanation: Gravitational PE = mgh = 3 × 9.8 × 2 = 58.8 J.
8Which form of energy is stored in a stretched spring?
A.Elastic potential energy
B.Kinetic energy
C.Chemical energy
D.Thermal energy
Explanation: A stretched or compressed spring stores elastic potential energy (given by (1/2)kx²). The other energy forms do not describe a spring's stored energy.
9Ohm's law relates voltage (V), current (I), and resistance (R) as:
A.V = IR
B.V = I/R
C.V = R/I
D.I = V × R
Explanation: Ohm's law: V = IR (voltage = current × resistance). Rearranged, I = V/R and R = V/I.
10A circuit has a 12 V battery and a 4 Ω resistor. What current flows?
A.3 A
B.48 A
C.0.33 A
D.8 A
Explanation: I = V/R = 12 V / 4 Ω = 3 A.

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

The Yamagata Prefectural Public High School Entrance Examination in Science (理科) tests lower-secondary graduates across physics, chemistry, biology and earth science, with many sub-questions and diverse answer formats. From 2026 (令和8年度) a new two-stage system replaces the old 推薦選抜: a 前期(特色)選抜 (each school chooses 1-3 of 個人面接・集団面接・作文・発表・小論文・実技・口頭試問・学校独自学力検査, plus 調査書; A日程 1/20(火) or B日程 2/3(火)) and a 後期(一般)選抜 (five-subject 学力検査 plus 調査書). The general academic test (学力検査) is a prefecture-wide common paper covering five subjects (国語, 社会, 数学, 理科, 英語), each worth 100 points (合計 500点); for 令和8年度 the 後期 学力検査 is sat on a single day, 3月7日(土). The 理科 common paper (12:50-13:40, sat fourth; 大問8題) is balanced across 生物・地学・化学・物理, has many sub-questions 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 (500) with the 調査書 (中3 45点 → 500点換算) on the school-chosen ratio (3:7/4:6/5:5/6:4/7:3), with each school setting its own比重 and some applying 傾斜配点 (1.5×). 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

100-point paper (大問8題) aligned to the MEXT 理科 Course of Study, covering physics (25%), chemistry (25%), biology (25%) and earth science (25%). 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 many sub-questions and diverse answer formats. The five academic-test subjects each carry 100 points (合計 500点), and 理科 is sat fourth on the single 学力検査 day (令和8年3月7日(土), 12:50-13:40). 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 Yamagata Prefectural Board of Education does not publish per-topic percentage weights for the 理科 paper, but its eight 大問 are split two each across 生物, 地学, 化学 and 物理, which is the basis for the even 25% quarters used here.

Time Limit

Sat as part of the one-day five-subject 学力検査 (合計 500点, each subject 100 points) on 令和8年3月7日(土): 国語 (8:50-9:40), 数学 (10:00-10:50), 社会 (11:10-12:00), 理科 (12:50-13:40, sat fourth) and 英語 (14:00-14:50) in that order (each 50 minutes).

Yamagata 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.
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.
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.
5For 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.
6Time the paper tightly — 大問8題 with many sub-questions means careful pacing; do not get stuck on one 資料読取 item.

Frequently Asked Questions

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

No. The official paper (大問8題) is balanced across 生物・地学・化学・物理, with many sub-questions 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 Yamagata 理科 paper and what is it worth?

It is scored out of 100 points, one of five subjects totalling 500 points (each subject 100 points). 理科 is sat fourth on the single 学力検査 day (令和8年3月7日(土), 12:50-13:40). The 前期(特色)選抜 検査 is on A日程 1月20日(火) or B日程 2月3日(火). Calculators are not permitted.

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; it has many sub-questions. 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) Yamagata uses a two-stage system: 前期(特色)選抜 (each school chooses 1-3 of 面接・作文・発表・小論文・実技・口頭試問・学校独自学力検査, plus 調査書; A日程 1/20(火) or B日程 2/3(火)) and 後期(一般)選抜 (five-subject 学力検査 plus 調査書). The 後期 combines the 学力検査 total (5 subjects × 100 = 500 points) with the 調査書 (中3 9教科×5 = 45点, converted to a 500-point basis) on the school-chosen ratio (3:7/4:6/5:5/6:4/7:3). Each school may apply 傾斜配点 (a 1.5× weighting on one or two specified subjects; for 令和8年度 every school that uses it applies the 1.5× to 数学 and 外国語(英語), not to 理科). Selection is relative to other applicants, not against a published pass line.

How much is the examination fee?

The 入学者選抜手数料 is ¥2,200 for a full-time (全日制) course (¥950 for 定時制, ¥300 for 通信制); it may be reduced or waived in cases of financial hardship.
