Everyday Science for One Paper: Quick Revision Guide

The Everyday Science Advantage

Everyday Science is a unique subject in one paper exams — it doesn't require deep technical knowledge, just awareness of how the world works. With smart preparation, it's one of the easiest sections to score 80%+ in. Here's your quick revision guide.

Biology Essentials

Human body basics: Blood groups (A, B, AB, O and Rh factor), largest organ (skin), smallest bone (stapes), largest gland (liver), and normal body temperature (37°C / 98.6°F).

Vitamins & deficiency diseases: This is the #1 most tested biology topic.

• Vitamin A → Night blindness
• Vitamin B1 → Beriberi
• Vitamin C → Scurvy
• Vitamin D → Rickets
• Vitamin K → Blood clotting issues

Practice these patterns with our Everyday Science MCQs.

Physics Concepts

Speed of light: 3 × 10⁸ m/s. Speed of sound: 343 m/s (in air). Newton's Laws: Especially the third law (action-reaction) appears frequently.

Units of measurement: Ampere (current), Joule (energy), Pascal (pressure), Hertz (frequency), Watt (power). Know the SI units table.

Chemistry Basics

pH scale: 0-14 (7 is neutral, below is acidic, above is basic). Periodic table: Lightest element (Hydrogen), most abundant in Earth's crust (Oxygen), in atmosphere (Nitrogen at 78%).

Common compounds: NaCl (table salt), H₂O (water), CO₂ (carbon dioxide), CaCO₃ (limestone/marble).

Environmental Science

Ozone layer: Located in stratosphere, protects from UV rays, depleted by CFCs. Global warming: Caused by greenhouse gases (CO₂, methane). Renewable energy: Solar, wind, hydel, geothermal.

Environmental topics are increasingly appearing in FPSC and NTS papers.

Technology & Inventions

Most tested inventions: Telephone (Alexander Graham Bell), Penicillin (Alexander Fleming), Dynamite (Alfred Nobel), Electric bulb (Thomas Edison), Printing press (Gutenberg), World Wide Web (Tim Berners-Lee).

Space & Astronomy

Nearest star (Sun), nearest planet to Sun (Mercury), largest planet (Jupiter), number of planets (8), first satellite (Sputnik 1957), first man in space (Yuri Gagarin 1961), first moon landing (Apollo 11, 1969).
