Physics in Everyday Life: Enhancing Quality of Life Through Science

Explore how physics principles improve household tasks, health, safety, work productivity, and leisure activities in daily life for Grade 11 students.

Education◦
General Science: Physics in Everyday Life 1. Term 1 / Week 1 2. Grade 11 3. Learning Area: General Science 4. Teachers: Jerome M. Boado & Diana Jane T. Lagundino
Learning Objectives 1. Identify various ways physics enhances our quality of life across different areas, including: 2. Household activities 3. Health and safety 4. Work productivity 5. Leisure and recreation
Day 1: Introduction to Physics in Everyday Life 1. MOTIVATION: Look at pictures of common technologies and consider: 2. What technologies do you see in the pictures? 3. Which of these technologies do you use every day? 4. How do these technologies make your life easier? 5. What concepts of physics might be involved in these technologies?
Importance of Physics in Daily Life 1. Household Activities: Makes chores easier through machines and appliances (e.g., Electric fan, washing machine). 2. Health and Safety: Improves medical care and protects people (e.g., X-ray machines, seatbelts). 3. Work Productivity: Increases efficiency and communication (e.g., Computers, internet). 4. Leisure and Recreation: Enhances entertainment and sports (e.g., Television, sports equipment).
Day 1: Guide Questions & Home Activity 1. GUIDE QUESTIONS: 2. 1. How does physics affect our daily activities? 3. 2. Why is physics important? 4. HOME-BASED ACTIVITY: 5. List five objects at home that apply physics principles.
Day 2: Physics in Household Activities (Part 1) 1. Physics explains how appliances work using concepts like electricity, force, motion, energy, heat, and magnetism. 2. Electric Fan: Electrical energy is converted into mechanical energy, causing the blades to rotate. 3. Washing Machine: The motor spins the drum, using force and motion to clean clothes. 4. Refrigerator: Removes heat from inside and transfers it outside to keep food cold.
Day 2: Physics in Household Activities (Part 2) 1. Microwave Oven: Microwaves transfer energy to food particles, causing them to vibrate and produce heat. 2. Flat Iron: Electrical energy is converted into thermal energy to remove wrinkles. 3. Flashlight: Batteries provide electrical energy converted into light energy. 4. Bicycle: Pedaling applies force that causes the bicycle to move forward.
Day 2: Guide Questions & Home Activity 1. GUIDE QUESTIONS: 2. 1. How do appliances make work easier? 3. 2. What principles of physics are involved? 4. HOME-BASED ACTIVITY: 5. Identify three appliances and explain their uses.
Day 3: Physics in Health and Safety - Motivation 1. How does an X-ray help doctors and patients? 2. X-rays use electromagnetic waves to produce images of bones and internal organs. 3. Why is wearing a seatbelt important? 4. Seatbelts use the concepts of force, motion, and inertia to protect passengers during sudden stops. 5. How do X-rays and seatbelts improve our health and safety?
Physics in Medical Technology 1. X-ray Machine (Electromagnetic waves): Helps see bones and detect fractures. 2. MRI (Magnetism and radio waves): Produces detailed images of organs and tissues. 3. Ultrasound (Sound waves): Allows viewing of developing babies or internal organs. 4. Thermometer (Heat and temperature): Measures body temperature to detect fever. 5. Laser Equipment (Light energy): Used in eye surgery and medical treatments.
Physics in Safety Devices 1. Seatbelt (Inertia and force): Prevents passengers from moving forward during sudden stops. 2. Airbag (Force and momentum): Reduces the impact during collisions. 3. Helmet (Force and energy absorption): Protects the head from injuries. 4. Smoke Detector (Electricity and light): Detects smoke and warns of fire. 5. Fire Extinguisher (Pressure): Helps control and put out fires.
Day 3: Guide Questions & Home Activity 1. GUIDE QUESTIONS: 2. 1. How does physics improve health care? 3. 2. Why are safety devices important? 4. HOME-BASED ACTIVITY: 5. Research one medical device that uses physics.
