Its editorial learning areas include Physics: measurements, energy and circuits; Chemistry: particles, reactions and mass; Biology: cells, inheritance and evidence; Earth science: time, weather and models. The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. Topics on this exam: Physics: measurements, energy and circuits, Chemistry: particles, reactions and mass, Biology: cells, inheritance and evidence, and Earth science: time, weather and models. The Tokyo Metropolitan Public High School Entrance Examination - Science study guide has 4 sections and about 1,247 words.
01Physics: measurements, energy and circuits
Begin a calculation by defining the system and converting units. Average speed is total distance divided by elapsed time, whereas average velocity uses displacement and includes direction. The signed area under a velocity-time graph gives displacement. To obtain total distance, add the magnitudes of areas where velocity is positive or negative.

Separate a substance description from a separation method. A pure substance has a definite chemical identity; a mixture contains constituents in variable proportions. Filtration can separate a suitable insoluble solid from a liquid, but dissolved salt passes through ordinary filter paper. Evaporation can recover a nonvolatile dissolved solid.

Use the level of organization requested in the task: an organ contains tissues, and tissues contain cells. A typical plant cell may have a cell wall and a large vacuole, but a drawing does not establish that every plant cell has visible chloroplasts. Photosynthesis in chloroplast-containing tissues uses light energy to build organic material from carbon dioxide and water. Aerobic respiration releases usable energy through processes involving oxygen.

Build a geological sequence from stated relationships rather than a page position. In an undisturbed sedimentary sequence, lower layers were deposited before higher layers. An intrusion or fault is younger than the rocks it cuts. Folding occurred after the affected layers formed.
