Science & Tech: Innovations, Ethics & Future Trends

TAKEAWAYS:

• Science and technology advance society but raise ethical questions like privacy and job displacement.
• Key innovations (AI, biotech, space tech) are analyzed through their societal impacts.
• Critical reading skills focus on identifying arguments, evidence, and biases in tech-related texts.
• Writing tasks require structured essays on tech’s pros/cons or futuristic scenarios.
• Grammar links: modal verbs for hypotheticals ("could revolutionize") and relative clauses for definitions.
• NEB-style questions test comprehension, summary, and creative responses to tech scenarios.

What is Science and Technology?

Science is the systematic study of nature, while technology is the application of scientific knowledge to solve problems. Together, they drive progress but also create challenges.

Key Areas in Unit 8

1. Major Scientific Discoveries

   • Space Exploration: Missions like Apollo 11 (1969) or Mars rovers (e.g., Perseverance) show human ambition.
   • Medical Breakthroughs: Vaccines (e.g., COVID-19 mRNA vaccines), CRISPR gene editing.
   • Energy Innovations: Solar panels, wind turbines, and nuclear fusion research.

2. Ethical Dilemmas

   • Privacy vs. Convenience: Social media tracking (e.g., Facebook’s data use) vs. personalized ads.
   • AI and Jobs: Automation replacing roles (e.g., self-checkout machines) but creating new ones.
   • Genetic Engineering: Designer babies (e.g., CRISPR babies in China) and long-term risks.

3. Future Trends

   • Artificial Intelligence (AI): Self-driving cars, chatbots (like me!), and AI in healthcare.
   • Biotechnology: Lab-grown meat, 3D-printed organs.
   • Climate Tech: Carbon capture, vertical farming.

How Science and Technology Work Together

Science explains phenomena (e.g., gravity, DNA), while technology uses that knowledge (e.g., GPS, gene therapy). Example: The discovery of penicillin (science) led to antibiotics (technology), saving millions.

Advantages and Disadvantages

Pros of Science and Technology

• Improved Health: Vaccines, surgeries, and telemedicine.
• Efficiency: Renewable energy reduces pollution.
• Communication: Internet connects the world instantly.

Cons of Science and Technology

• Environmental Harm: E-waste, deforestation for tech minerals.
• Social Issues: Cyberbullying, misinformation (fake news).
• Dependence: Over-reliance on tech (e.g., GPS for navigation).

Critical Reading: Analyzing Tech Texts

NEB exams test your ability to summarize, analyze, and evaluate texts about science/tech. Look for:

1. Main Idea: What is the text’s central argument?
   • Example: "AI will replace 30% of jobs by 2030" → Focus on job displacement.
2. Evidence: Facts, statistics, or examples used.
   • Example: "A 2022 study found 63% of tasks can be automated."
3. Bias: Is the author pro-tech or critical? Watch for loaded words.
   • Example: "Revolutionary breakthrough" vs. "Dangerous experiment."

Worked Example: Analyzing a Text

Text: "Social media algorithms manipulate users by showing them content that keeps them engaged, often at the cost of mental health."

• Main Idea: Algorithms harm mental health.
• Evidence: "Showing content that keeps them engaged" (e.g., endless scrolling).
• Bias: Critical of social media (uses "manipulate" and "cost").

Writing Tasks: Essays on Science and Technology

NEB often asks for structured essays (150–200 words) on topics like:

• "The impact of AI on society."
• "Should genetic engineering be regulated?"

Essay Structure

1. Introduction: State the topic and your stance.
   • Example: "Science and technology have transformed modern life, but their ethical implications cannot be ignored."
2. Body Paragraphs:
   • Point 1: Advantage (e.g., AI improves healthcare).
   • Point 2: Disadvantage (e.g., AI creates job losses).
   • Point 3: Ethical concern (e.g., privacy risks).
3. Conclusion: Summarize and suggest solutions.
   • Example: "While AI offers benefits, strict regulations are needed to protect society."

Sample Essay: "The Pros and Cons of Space Exploration"

Space exploration is one of humanity’s greatest achievements, but it also raises ethical questions. On one hand, missions like the Mars rover have expanded our knowledge of the universe and inspired innovation. For example, technologies developed for space (e.g., memory foam) now benefit everyday life. On the other hand, space exploration is extremely expensive, diverting funds from education or healthcare. Additionally, rocket launches pollute the atmosphere with carbon emissions. While the risks exist, the long-term benefits—such as discovering alien life or new energy sources—outweigh the costs. Governments should invest wisely, prioritizing sustainable and ethical exploration.

Grammar Focus: Modals and Relative Clauses

1. Modal Verbs for Hypotheticals:

   • Could: "AI could replace doctors in the future."
   • Should: "Scientists should regulate genetic engineering."
   • Might: "Climate change might lead to food shortages."

2. Relative Clauses for Definitions:

   • Example: "A robot, which performs tasks automatically, is used in factories."
   • Reduced form: "A robot, performing tasks automatically..."

NEB-Style Questions and Answers

Question 1: Comprehension (10 marks)

Text: "The invention of the internet has revolutionized communication. However, it has also created new problems like cybercrime and misinformation."

• a) What is the main idea? (2 marks) Answer: The internet has both positive (revolutionized communication) and negative (cybercrime, misinformation) effects.
• b) Give one example of cybercrime. (2 marks) Answer: Hacking, identity theft, or phishing scams.
• c) How does misinformation spread? (3 marks) Answer: Through social media, fake news websites, and viral rumors. People share unverified content without checking sources.
