Introduction: Technology and the Family

Welcome to this study guide! In this chapter, we are looking at how technological, scientific, and environmental changes have transformed family life in Hong Kong over the past forty years. It’s not just about smartphones and computers—it’s about the food we eat, the clothes we wear, and how we spend our time together as a family.

Understanding these changes is crucial for the HKDSE because they affect our lifestyle, our choices as consumers, and the quality of life we enjoy at home.

1. Technological and Scientific Changes

Science and technology have moved from the laboratory into our living rooms and kitchens. These changes usually aim to make life more convenient or to improve the products we use every day.

A. Impact on Food and Nutrition (Strand A)

Technological advancement has changed how families plan and prepare meals:

  • Time- and Labour-saving Devices: Appliances like microwave ovens and induction cookers have simplified cooking processes. This allows busy working parents to prepare meals more quickly.
  • Advanced Preparation Techniques: Technology allows for better food preservation, such as irradiation (using radiation to kill bacteria) and UHT (Ultra-High Temperature) processing, which extends the shelf life of food.
  • Genetically Modified (GM) Food: Scientific changes have led to the development of GM foods, which can be designed to have better nutritional value or a longer shelf life.

B. Impact on Clothing and Textiles (Strand B)

Fashion isn't just about style; it's about the science of the fabrics we wear:

  • Newly Developed Fibres: Science has given us high-performance materials like Tencel and micro-fibre. These offer families more choices for comfort, durability, and easy care.
  • Industrial Technologies: The use of Computer-Aided Design (CAD) and laser technology in garment construction has made clothing production more efficient, often making fashion more affordable for families.
  • Smart and Functional Textiles: New finishes can make clothes stain-resistant, anti-bacterial, or wrinkle-free, reducing the time families spend on laundry and maintenance.

Quick Review: Technological changes usually focus on efficiency (saving time) and functionality (better products).

2. Environmental Change and Sustainable Development

In recent years, families have become much more aware of their "environmental footprint." This means we consider how our consumption affects the planet.

The Concept of Sustainable Development

Families are increasingly making choices that meet their current needs without harming the ability of future generations to meet theirs. This is known as sustainable development.

Environmental Impact on Choices:

  • Green Textiles: Many families now look for "eco-friendly" or "green" clothing made from recycled materials or fibres that require less water and pesticides to grow.
  • Food Choices: There is a growing trend toward choosing food with less packaging or supporting organic farming to reduce the chemical impact on the environment.
  • Waste Reduction: Families are more conscious of food spoilage and the environmental cost of throwing away clothes (the "fast fashion" impact).

Did you know? Environmental protection is now a major factor influencing Consumer Behaviour. When you choose a product because it is "green," you are practicing social responsibility!

3. Impact on Family Ties and Lifestyle

How do these scientific and environmental changes actually change the way a family functions? Let's look at the "Family Dimension":

A. Changing Lifestyle and Quality of Life

With time-saving devices, family members may have more leisure time. However, in Hong Kong, this time is often used for work or extra-curricular activities, which can ironically sometimes decrease the "quality" time spent together.

B. Financial Considerations

While technology can make some things cheaper, staying "up-to-date" with the latest scientific developments (like organic foods or high-tech fabrics) can put a strain on the family income.

C. Roles and Responsibilities

Scientific knowledge about nutrition (like the Food Pyramid and Nutrition Labelling) allows family members to take better care of each other’s health. Parents now use this information to prevent lifestyle diseases like obesity or high blood pressure in their children.

Memory Trick: Think of the 3 "E"s of change:
1. Efficiency (Technology saving time)
2. Evolution (Science improving products/nutrition)
3. Environment (Sustainability and green choices)

In the HKDSE exam, you may be asked to apply these family changes to a food or clothing context. Keep these connections in mind:

For Food (Strand A):
  • Scientific: Understanding pathogens (like Salmonellae or E. coli) and using technology (like HACCP) ensures family food safety.
  • Technological: Using a food composition table or reading nutrition labels to plan meals for different family milestones (e.g., elderly parents or growing children).
For Clothing (Strand B):
  • Scientific: Choosing fibres based on their absorbency or thermal insulation to suit the family's health needs and comfort.
  • Environmental: Looking for care labels to ensure clothes last longer, reducing waste and saving money.

Key Takeaways for the Exam

  • Technology provides time- and labour-saving devices that alter family daily routines.
  • Science introduces new materials (fibres) and food processes (GM, irradiation) that affect health and choice.
  • Environmental concerns lead families toward sustainable development and "green" consumption.
  • All these factors influence the quality of life and consumer behaviour within the family unit.

Common Mistake to Avoid: Don't just list gadgets! Always explain how the gadget or scientific discovery changes the lifestyle or ties of the family members.
