PPSC Educators Test Everyday Science Flashcards
50 question-and-answer cards covering Everyday Science as it is examined in PPSC Educators Test. 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Everyday Science deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
What is the function of the cell membrane and the nucleus?
The cell membrane controls the entry and exit of substances; the nucleus controls all cell activities and contains genetic material (DNA).
What is the basic difference between plant and animal cells?
Plant cells have a cell wall, chloroplasts, and a large central vacuole; animal cells lack a cell wall and chloroplasts and have small vacuoles.
Define tissue and organ.
A tissue is a group of similar cells performing a common function; an organ is a group of different tissues working together to perform a specific function.
Which organelle is called the 'powerhouse of the cell' and why?
The mitochondrion, because it produces energy (ATP) through cellular respiration.
What is the function of the human digestive system, and where is most absorption?
It breaks down food into absorbable nutrients; most absorption of nutrients occurs in the small intestine.
What is the main function of the respiratory system?
To take in oxygen and remove carbon dioxide; gas exchange occurs in the alveoli of the lungs.
How many chambers does the human heart have, and what are they?
Four chambers: two upper atria (right and left) and two lower ventricles (right and left).
What is the largest organ of the human body, and what is the largest internal organ?
The skin is the largest organ overall; the liver is the largest internal organ.
Name the deficiency diseases caused by lack of Vitamin C and Vitamin D.
Vitamin C deficiency causes scurvy; Vitamin D deficiency causes rickets (in children) and osteomalacia (in adults).
Which vitamin deficiency causes night blindness, and which causes beriberi?
Vitamin A deficiency causes night blindness; Vitamin B1 (thiamine) deficiency causes beriberi.
What are the main macronutrients in food and their primary roles?
Carbohydrates (energy), proteins (growth and repair), and fats (energy storage and insulation).
Which mineral deficiencies cause anaemia and goitre?
Iron deficiency causes anaemia; iodine deficiency causes goitre.
What are the main gases in Earth's atmosphere by percentage?
Nitrogen about 78%, oxygen about 21%, and argon, carbon dioxide, and other gases about 1%.
What is the role of the ozone layer, and which gases deplete it?
The ozone layer (in the stratosphere) absorbs harmful ultraviolet (UV) radiation; it is depleted mainly by chlorofluorocarbons (CFCs).
Name the main greenhouse gases responsible for global warming.
Carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), water vapour, and CFCs.
Differentiate between renewable and non-renewable natural resources.
Renewable resources can be replenished naturally (e.g., solar, wind, water, forests); non-renewable resources are finite and deplete with use (e.g., coal, oil, natural gas).
What is an ecosystem, and what is a food chain?
An ecosystem is a community of living organisms interacting with their non-living environment; a food chain is the sequence of who eats whom, showing energy transfer (producers → consumers → decomposers).
What does LASER stand for?
Light Amplification by Stimulated Emission of Radiation.
What technologies do GPS and RADAR use?
GPS (Global Positioning System) uses satellites to determine location; RADAR (Radio Detection and Ranging) uses radio waves to detect the position and speed of objects.
List the planets of the solar system in order from the Sun.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Which is the largest planet and which is the closest to the Sun?
Jupiter is the largest planet; Mercury is the closest planet to the Sun.
What causes day and night, and what causes the seasons?
Day and night are caused by Earth's rotation on its axis (24 hours); seasons are caused by Earth's revolution around the Sun combined with the tilt of its axis.
Name the layers of the Earth's interior from outside to inside.
Crust, mantle, outer core (liquid), and inner core (solid).
What instrument measures earthquakes and atmospheric pressure?
A seismograph measures the intensity of earthquakes; a barometer measures atmospheric pressure.
What this deck covers
The Everyday Science deck follows the PPSC Educators Test Everyday Science syllabus — 5 chapters and 14 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 10.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 109 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
Everyday Science flashcards FAQ
How many Everyday Science flashcards are in this PPSC Educators Test deck?
50 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these PPSC Educators Test flashcards free?
Yes. The preview here is free to read with no signup, and the full 50-card deck is free inside the Examius app.
What do the Everyday Science cards cover?
They follow the PPSC Educators Test Everyday Science syllabus — 5 chapters and 14 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
