Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. The bites below come from this kit — swipe through them in the app.
💡 Key Idea
Science is a way of thinking.
Science is not a fixed set of facts — it is a systematic process for testing ideas against evidence from the natural world.
↳ Science advances by testing ideas with evidence, not by accepting claims on authority.
📖 Definition
Master these words first.
↳ A hypothesis is a guess to be tested; a theory is an explanation that has survived testing.
⚖️ Comparison
Stop mixing up these two words.
↳ In everyday speech 'theory' means a guess — in science it means a strongly supported explanation.
⚠️ Common Mistake
Science is not a pile of facts.
↳ Scientific knowledge is reliable but always open to revision — that is its strength, not a weakness.
⚙️ Process
Five steps that build real knowledge.
A good experiment changes one variable at a time while keeping all others constant, so the cause of any effect is clear.
↳ Controlled experiments isolate cause and effect by changing only one variable.
⭐ Important Fact
Physics, chemistry, biology — one universe.
These branches overlap constantly — biochemistry studies life's molecules, and biophysics studies living systems with physics laws.
↳ The branches of science are lenses on the same natural world, not separate worlds.
🌍 Real World
You use science every single day.
↳ Everyday technology is applied science — understanding the science explains the technology.
🎯 Exam Tip
Answer with the right vocabulary.
↳ Examiners reward precise scientific vocabulary and clearly separated observation vs inference.
🧠 Memory Trick
One acronym, five steps.
Use OHECC: Observe → Hypothesise → Experiment → Collect data → Conclude.
↳ OHECC keeps the five steps of the scientific method in order.
❓ Did You Know
Even Einstein was revised.
Newton's laws of motion were considered complete for over 200 years — until Einstein's relativity showed they break down at very high speeds and huge masses.
↳ New evidence can refine even the most established scientific ideas.
Science opens many doors.
↳ A science foundation supports careers far beyond the laboratory.
Science is the systematic study of the natural world through observation, experimentation, and reasoning. It builds reliable knowledge by testing ideas against evidence, and it spans disciplines like physics, chemistry,…
