Everyday Science MCQs & Quiz Questions 2026 — 100 Q&A

What Is Everyday Science?

Everyday Science is a distinct subject tested in Pakistan's competitive examinations, including FPSC, PPSC, NTS, KPPSC, SPSC and BPSC tests. Unlike specialized academic science papers, Everyday Science focuses on practical, easily observable scientific facts that any well-informed candidate should know — covering basic physics, chemistry and biology in a general-knowledge style rather than requiring deep technical expertise.

States of Matter and Basic Physics

One of the most frequently tested Everyday Science topics is the states of matter. Matter commonly exists in three states: solid, liquid and gas, distinguished by how tightly their particles are packed and how much energy those particles have. A fourth state, plasma, consists of ionized gas and is found in phenomena such as lightning and the sun. Evaporation, the process by which a liquid changes into a gas, is a cooling process because it requires energy to be absorbed from the surrounding liquid.

Simple machines are another common topic. The six classical simple machines are the lever, wheel and axle, pulley, inclined plane, wedge, and screw — each designed to make work easier by changing the direction or magnitude of an applied force.

Basic Chemistry Facts

Everyday Science chemistry questions typically focus on commonly encountered substances and reactions rather than advanced organic chemistry. Key facts include: water has the chemical formula H₂O and boils at 100°C at standard atmospheric pressure; acids have a pH below 7 and bases have a pH above 7, with pure water sitting at a neutral pH of 7; and the most abundant gas in Earth's atmosphere is nitrogen (about 78%), followed by oxygen (about 21%).

Basic Human Biology

Human biology questions in Everyday Science quizzes typically cover the major organ systems and commonly known facts about the human body. The adult human body contains 206 bones and is made up of roughly 37 trillion cells. The heart, a muscular organ about the size of a fist, pumps blood through the circulatory system, while the lungs facilitate the exchange of oxygen and carbon dioxide during respiration. The human body's normal core temperature is approximately 37°C (98.6°F).

Everyday Science for Competitive Exams

Because Everyday Science blends physics, chemistry and biology into a single general-knowledge style paper, the most efficient way to prepare is broad, repeated practice across all three areas rather than deep specialization in any one. FPSC, PPSC and NTS questions in this subject tend to recur in similar forms across different exam cycles, making consistent quiz practice one of the most effective preparation strategies.

Conclusion

Everyday Science rewards broad curiosity over narrow expertise — a little knowledge across physics, chemistry and biology goes a long way, both in competitive exams and in everyday life. Test your knowledge with our Everyday Science Quiz and track your progress on the global leaderboard!
