Chapter Content

Here are some jackets of books. Discuss with your partner which of these look like jackets of science fiction books. Why do you think so? Give some reasons.

Detailed Explanation

This chunk prompts students to analyze book jackets to determine which might belong to science fiction books. The exercise encourages critical thinking and discussion among peers. Students should look for visual elements like futuristic images, space themes, or technological motifs common in science fiction. This helps them articulate their reasoning by considering aspects such as color, illustrations, and typography.

Examples & Analogies

Think about browsing in a bookstore. When you see covers with spaceships or robots, you might instantly feel they are sci-fi. Just like how we recognize certain signs in the world, book jackets can communicate genres through design.

Chapter Content

The story ‘The Fun They Had’ takes us to the world of the future where children study in a virtual classroom. The learning is through computer software or the Internet, or virtual: carried out, accessed, or stored by means of a robotic teacher.

Detailed Explanation

This portion introduces a futuristic setting where traditional classrooms have evolved into virtual environments. Students engage with learning materials online and are taught by robotic teachers. This concept reflects the growing use of technology in education, emphasizing how it can make learning more interactive and accessible. Virtual classrooms may also allow for personalized learning experiences, catering to a student’s pace and preferences.

Examples & Analogies

Imagine attending a class from your home while wearing VR glasses. Instead of sitting at a desk, you could be in a spaceship or under the ocean, learning about space or marine biology, making education an adventure.

Chapter Content

GPS (Global Positioning System) which started out as a military technology is now being used to hail taxis, get mapping directions, etc. Likewise, drones had started out as a military technology, but are increasingly being used for a wide range of consumer and commercial applications.

Detailed Explanation

This part reveals how technologies initially created for military purposes, like GPS and drones, have become integral to everyday life. GPS now aids navigation and delivery services, while drones are used for tasks such as infrastructure inspection and emergency supply delivery. The potential for flying cars is also introduced, suggesting the future of personal transportation could blend air and road travel, significantly altering how we perceive distance and traffic.

Examples & Analogies

Imagine needing a package urgently delivered. Drones can act like tiny delivery superheroes, flying directly to your door, while GPS guides them, showing exactly where to land. As this technology evolves, the idea of flying cars becomes a reality where hopping in your vehicle could one day mean taking to the skies.
