Here are the answers to Question 5 and Question 6: Question 5: a) i. The design process is a systematic approach used to solve problems or create new products. It involves a series of steps from identifying a need to developing and refining a solution. a) ii. Four stages of the design process are: 1. Investigation/Research: Understanding the problem and gathering information. 2. Ideation/Generation of ideas: Brainstorming and developing potential solutions. 3. Development/Prototyping: Creating a model or prototype of the chosen solution. 4. Testing and Evaluation: Assessing the prototype's effectiveness and making improvements. b) Testing*: This is the stage where the designed product or solution is put through various trials to see if it functions as intended and meets the specified requirements. It helps identify flaws or areas for improvement. Evaluation*: This involves critically assessing the success of the design against the initial problem statement and criteria. It determines how well the product solves the problem and if any modifications are needed before final production. c) To design a product to reduce plastic waste in your school: i. State the problem*: The problem is the excessive accumulation of single-use plastic waste (e.g., plastic bottles, wrappers) in the school environment, leading to pollution and poor sanitation. ii. Suggest a solution (artifact): A reusable water bottle collection and refill station*. iii. State two materials you will use*: 1. Stainless steel (for the refill station structure) 2. Recycled plastic (for the collection bins) Question 6: a) i. Waste management is the process of collecting, transporting, processing, recycling, or disposing of waste materials. It aims to reduce the harmful effects of waste on human health and the environment. a) ii. Three types of waste are: 1. Solid waste (e.g., household garbage, plastics) 2. Liquid waste (e.g., wastewater, industrial effluents) 3. Hazardous waste (e.g., chemicals, batteries) b) Three effects of poor waste disposal are: 1. Environmental pollution: Improper disposal contaminates soil, water bodies, and air, harming ecosystems and wildlife. 2. Health hazards: Accumulation of waste creates breeding grounds for pests and disease-carrying organisms, leading to the spread of illnesses like cholera and malaria. 3. Unpleasant odors and aesthetics: Piles of rotting waste produce foul smells and make the community look unsightly, reducing the quality of life. c) Three ways of managing waste in your community are: 1. Implement a recycling program: Encourage residents to separate recyclable materials like plastics, paper, and glass for collection and processing. 2. Promote composting: Educate the community on composting organic waste (food scraps, yard waste) to create nutrient-rich soil, reducing landfill waste. 3. Organize regular community clean-up campaigns: Mobilize residents to participate in scheduled clean-ups to remove litter and illegally dumped waste from public spaces. 3 done, 2 left today.
