Class 8 English Unit 3 Question Answer
8th Standard English Talking of Science Question Answer
Question 1.
Do you think that asking questions is fundamental to all scientific exploration? How do questions move science forward?
ചോദ്യങ്ങൾ ചോദിക്കുന്നത് എല്ലാ ശാസ്ത്രീയ പര്യ വേക്ഷണങ്ങൾക്കും അടിസ്ഥാനമാണെന്ന് നിങ്ങൾ കരുതുന്നുണ്ടോ? ചോദ്യങ്ങൾ എങ്ങനെയാണ് ശാസ്ത്ര ത്തെ മുന്നോട്ട് നയിക്കുന്നത്?
Answer:
Yes, asking questions is fundamental to all scientific exploration. Questions move science forward because every scientific discovery begins with a question like “Why does this happen?” or “How does this work?”. These questions create a problem to be solved. Scientists then conduct experiments and do research to find the answer. Each new answer can lead to more questions, and this continuous cycle of questioning and seeking answers is what drives scientific progress.
Question 2.
‘Curiosity is at the heart of science.’ Do you agree?
ജിജ്ഞാസയാണ് ശാസ്ത്രത്തിന്റെ ഹൃദയം. നിങ്ങൾ യോജിക്കുന്നുണ്ടോ?)
Answer:
Yes, I completely agree with this statement. Curiosity is the deep desire to know or learn something new. As Dr. Ajith said in the interview, this curiosity is what “drives the quest for knowledge.” Without curiosity, a person would not ask questions or search for answers, and therefore, science would not exist.
Question 3.
How does observation help us understand natural phenomena?
പ്രകൃതി പ്രതിഭാസങ്ങളെ മനസ്സിലാക്കാൻ നിരീക്ഷണം നമ്മെ എങ്ങനെ സഹായിക്കുന്നു?
Answer:
Observation is the first and most important step in understanding natural phenomena. By carefully watching something-like the stars at night, a plant growing, or the weather changing-we can collect information and notice patterns. This helps us to ask meaningful questions and form an initial guess (a hypothesis). Scientists then test this guess through experiments, which also require careful observation.
Question 4.
What are the unsolved mysteries you would like to solve, with the help of science?
ശാസ്ത്രത്തിന്റെ സഹായത്തോടെ നിങ്ങൾ പരിഹരിക്കാ ൻ ആഗ്രഹിക്കുന്ന ഉത്തരം കിട്ടാത്ത രഹസ്യങ്ങൾ എന്തെ ല്ലാമാണ്?
Answer:
With the help of science, I would like to solve some of these mysteries:
- Is there life on other planets in our universe?
- Can we find a complete cure for diseases like cancer?
- How can we generate clean energy for everyone without harming the planet?
- Is time travel possible?
Question 5.
Do you want to become a scientist? How will you equip yourself for this?
നിങ്ങൾക്ക് ഒരു ശാസ്ത്രജ്ഞനാകാൻ ആഗ്രഹമുണ്ടോ? ഇതിനായി നിങ്ങൾ എങ്ങനെ സ്വയം സജ്ജരാകും?
Answer:
Yes, I want to become a scientist. To equip myself for this, I will:
- Study my science and mathematics subjects well in school.
- Always stay curious and ask a lot of questions about the world around me.
- Read many science books and articles to understand what is already known.
- Try to do small science projects and experiments.
- As Dr. Ajith advised, I will follow my interest with passion and work hard.
Talking of Science Class 8 Question Answer – Let’s Rewind
Question 1.
Books remain a source of reliable information unlike most of what we get online.” Do you agree? Give reasons.
ഓൺലൈനിൽ ലഭിക്കുന്ന മിക്ക വിവരങ്ങളെയും പോലെ യല്ലാതെ, പുസ്തകങ്ങൾ വിശ്വസനീയമായ വിവരങ്ങളു ടെ ഉറവിടമായി നിലനിൽക്കുന്നു. നിങ്ങൾ യോജിക്കു ന്നുണ്ടോ? കാരണങ്ങൾ നൽകുക.
Answer:
Yes, I agree with this statement. Books are generally more reliable because they are often written by experts and go through a process of editing and fact-checking before they are published. In contrast, a lot of information on the internet can be published by anyone without any verification, so it can sometimes be inaccurate, biased, or just a personal opinion rather than a fact.
Question 2.
How does asking questions help in developing our understanding?
ചോദ്യങ്ങൾ ചോദിക്കുന്നത് നമ്മുടെ ധാരണ വികസി പിക്കാൻ എങ്ങനെ സഹായിക്കുന്നു?
Answer:
Asking questions is the first step to learning. When we ask a question, we identify a gap in our knowledge. This pushes our minds to search for answers, which makes us read more, think critically, and connect different ideas. This active process of seeking answers helps us to develop a much deeper and clearer understanding of a topic.
Question 3.
Why does Dr. Ajith Parameswaran say that anyone can become a scientist?
എന്തുകൊണ്ടാണ് ഡോക്ടർ അജിത് പരമേശ്വരൻ ആർ ക്കും ഒരു ശാസ്ത്രജ്ഞനാകാം എന്ന് പറയുന്നത്?
Answer:
Dr. Ajith says that “anyone can become a scientist” because the most important quality needed is a child-like curiosity and a passion for knowledge. These are qualities that any person can have, regardless of their background. While becoming a world-famous scientist might be rare, anyone with curiosity and a willingness to work hard can learn, ask questions, and contribute to science.
Question 4.
What, in your opinion, are the essential qualities of a good scientist? Mention any two.
നിങ്ങളുടെ അഭിപ്രായത്തിൽ, ഒരു നല്ല ശാസ്ത്രജ്ഞന്റെ പ്രധാന ഗുണങ്ങൾ എന്തെല്ലാമാണ്? ഏതെങ്കിലും രണ്ട ണ്ണം പറയുക.
Answer:
In my opinion, two essential qualities of a good scientist are:
Deep Curiosity: A strong desire to always ask questions and understand why things are the way they are.
Honesty: The ability to look at evidence without bias, admit when they don’t know something, and accept the truth even if it is different from what they initially believed.
Question 5.
Do you now agree that science is entirely different from mere opinion? Why?
ശാസ്ത്രം കേവലം അഭിപ്രായത്തിൽ നിന്ന് തികച്ചും വ്യത്യ സ്തമാണെന്ന് നിങ്ങൾ ഇപ്പോൾ യോജിക്കുന്നുണ്ടോ? എന്തുകൊണ്ട്?
Answer:
Yes, I agree that science is entirely different from a mere opinion. An opinion is a personal belief that doesn’t need proof. Science, however, is a systematic method based on observation, experimentation, and evidence. A scientific conclusion is accepted only after it has been tested and verified, whereas an opinion is just what someone thinks or feels.

Talking of Science Class 8 Question Answer – Activity 3
Human-animal conflicts and extreme weather events such as flash floods and landslides are on the increase today.
A. Try to list some of the probable causes of these events.
• Misuse of land
• …………………………………….
• …………………………………….
• …………………………………….
മനുഷ്യ – മൃഗ സംഘർഷങ്ങളും, മിന്നൽ പ്രളയങ്ങൾ, ഉരു ൾപൊട്ടലുകൾ പോലുള്ള അതിതീവ്രമായ കാലാവസ്ഥാ സംഭവങ്ങളും ഇന്ന് വർദ്ധിച്ചുവരികയാണ്.
ഇവയുടെ സാധ്യമായ ചില കാരണങ്ങൾ പട്ടികപ്പെടു ത്താൻ ശ്രമിക്കുക.
Answer:
- Misuse of land
- Deforestation: Cutting down forests destroys animal habitats, forcing them to enter human areas. It also loosens soil, causing landslides.
- Climate Change and Global Warming: Increased pollution is warming the planet, leading to more intense, unpredictable rains and floods.
- Improper Waste Management: Dumping garbage near forests attracts wild animals to human areas.
- Construction in Ecologically Sensitive Areas: Building houses and resorts in hilly areas and near rivers increases the risk of natural disasters
B. List some mysteries of Nature that remain unsolved. Write a short note on any one of these mysteries.
പ്രകൃതിയിലെ, ഉത്തരം കണ്ടെത്താനാവാത്ത ചില രഹ സ്യങ്ങൾ പട്ടികപ്പെടുത്തുക. അവയിലൊന്നിനെക്കുറിച്ച് ഒരു ചെറു കുറിപ്പ് എഴുതുക.
Answer:
Some Unsolved Mysteries of Nature:
- Are we alone in the universe? (Is there extraterrestrial life?)
- What is dark matter and dark energy?
- How exactly did life begin on Earth?
- How do some animals migrate thousands of kilometers so accurately?
Short note on: Are we alone in the universe?
The universe is incredibly vast, with billions of galaxies, each containing billions of stars. Many of these stars likely have planets orbiting them, just like Earth orbits the Sun. This makes scientists believe that it is highly probable that life exists on other planets too. However, despite searching for signals with powerful telescopes for many years, we have not yet found any definite proof of life outside Earth. This question-whether we are the only living beings in this enormous cosmos-remains one of the biggest and most exciting unsolved mysteries of science.

Answer:
Suggestions to prevent natural calamities:
പ്രകൃതി ദുരന്തങ്ങൾ തടയാനുള്ള നിർദ്ദേശങ്ങൾ:
Plant More Trees (Afforestation): We must plant more trees because their roots hold the soil together, which helps prevent landslides. Forests also play a big role in controlling climate.
Stop Deforestation: We must stop cutting down forests, especially in hilly areas and on river banks.
Reduce Pollution: By using less plastic, saving electricity, and using public transport, we can help reduce global warming, which is a major cause of extreme weather.
Avoid Building in Sensitive Areas: We should avoid constructing large buildings in areas that are prone to floods and landslides.
Proper Waste Management: Never throw waste, especially plastic, into rivers, canals, and drainage systems, as this can block water flow and cause floods.

ശാസ്ത്രത്തിന്റെ കഥ, ലോകത്തെ മാറ്റിമറിച്ച കണ്ടുപിടുത്തങ്ങളുടെയും കണ്ടെത്തലുകളുടെയും കഥയാണ്. ഇനി, ലോക ത്തെ മാറ്റിമറിച്ച ശാസ്ത്രീയ കണ്ടുപിടുത്തങ്ങളെക്കുറിച്ച്, താഴെ നൽകിയിട്ടുള്ള സൂചകങ്ങൾ ഉപയോഗിച്ച് ഒരു ജസ്റ്റ് എ മിനിറ്റ് (JAM) പ്രസംഗം തയ്യാറാക്കാം.
• The name of the inventor(s)
• Impact of the invention/discovery
• Positive and negative effects.
Answer:
(JAM Speech on the Invention of the Wheel)
A very good morning to everyone. The invention I am going to talk about for the next minute is one of the most important in human history – the Wheel.
It’s hard to name a single inventor, as the wheel was likely invented around 3500 BC in Mesopotamia, but it wasn’t one person’s idea. The impact of the wheel was truly revolutionary. Initially used for making pottery, its most significant use came in transportation. Carts with wheels allowed people to transport heavy goods over long distances easily. This led to the growth of trade, agriculture, and the development of cities.
The positive effects are countless; from cars, trains, and airplanes to tiny gears in watches, our modern world runs on the principle of the wheel. However, one could argue that a negative effect is the pollution caused by the vehicles that depend on it.
In conclusion, the simple invention of the wheel set human civilization in motion, paving the way for almost every other mechanical invention that followed.
Thank you.

8th Standard English Talking of Science Question Answer – Activity 7
A. We have learned that curiosity and observation are important parameters of the scientific method. Let’s now conduct a simple experiment and observe the results.
Answer:
Dancing Raisins Experiment
Materials required:
(a) Raisins
(b) A glass
(c) Soda or sparkling water
(d) Water
Instructions:
1. Half-fill the glass with soda.
2. Drop 5 – 7 raisins into the soda.
3. Observe
4. Slowly pour water into the glass.
5. Observe what happens.
B. Now, prepare a detailed procedure of your experiment. The first and last sentences are given. Use appropriate linkers.
First, half-fill the glass with soda. Add some raisins to the carbonated solution.
…………………………………………………………………………………………………………………………….. …………………………………………………………………………………………………………………………….
…………………………………………………………………………………………………………………………….
………………………………………………………………………………………………………….. Finally, observe the raisins for a few minutes.
ഇനി, നിങ്ങളുടെ പരീക്ഷണത്തിന്റെ വിശദമായ പ്രവർ നക്രമം തയ്യാറാക്കുക. ആദ്യത്തെയും അവസാന ത്തെയും വാക്യങ്ങൾ നൽകിയിട്ടുണ്ട്. അനുയോജ്യമായ യോജിപ്പിക്കാനുള്ള വാക്കുകൾ (linkers) ഉപയോഗിക്കുക.
Answer:
First, half-fill the glass with soda. Next, gently drop five to seven raisins into the soda and observe their movement for a minute. After that, slowly pour plain water into the glass until it is about three-quarters full. Then, watch carefully to see how the addition of water affects the raisins. Finally, observe the raisins for a few minutes.
C. Now, describe what happens to the raisins when you pour water into the glass Why does this happen? Write your explanation in 2 – 3 sentences.
……………………………………………………………………………………………………………………………..
…………………………………………………………………………………………………………………………….
ഇനി, ഗ്ലാസിലേക്ക് വെള്ളം ഒഴിക്കുമ്പോൾ ഉണക്കമുന്തിരിക്ക് എന്ത് സംഭവിക്കുന്നു എന്ന് വിവരിക്കുക. എന്തുകൊണ്ടാണ് ഇത് സംഭവിക്കുന്നത്? നിങ്ങളുടെ വിശദീകരണം 2 – 3 വാക്യ ങ്ങളിൽ എഴുതുക.
Observation: When water is poured into the glass, the “dancing” movement of the raisins slows down, and eventually, they stop moving and sink to the bottom.
Explanation: This happens because the soda contains dissolved carbon dioxide gas. These tiny gas bubbles stick to the raisin’s surface, lifting it to the top. When we add plain water, it dilutes the soda, reducing the number of available gas bubbles. Without enough bubbles to lift them, the raisins can no longer float and therefore stop “dancing”.
