Understanding Physics Principles in Everyday Household Activities and Appliances
Explore how physics concepts like energy, motion, and heat transfer apply to common household appliances and activities, enhancing daily life and technology use.
LEARNING OBJECTIVES
1.Identify common
householdactivities and
appliances that involve
physics principles.
1.Create a simple
Household Physics
Mapping chart with
group members.
1.Appreciate the
importance of physics in
improving everyday
household life.
5.
• Divide theclass into small groups.
• One representative from each group will act
out a household-related concept without
speaking.
• Group members will guess the concept
being portrayed.
• After guessing correctly, the group explains
how physics is involved
6.
What forms ofenergy or motion did you observe
in the activity?
PHYSICS
is the sciencethat studies how things move and
interact in the world around us. It tries to
understand the basic rules that govern the
universe — from tiny atoms to huge planets
and galaxies.
10.
PHYSICS
In simple terms:
Physicsasks questions like:
⚬ Why do things fall down?
⚬ How does light travel?
⚬ What makes things move?
⚬ What is energy, and how is it used?
11.
PHYSICS
Some everyday examplesof physics:
⚬ A ball falling (gravity)
⚬ A car speeding up or slowing down
(motion and force)
⚬ Electricity turning on a light (energy and
circuits)
⚬ Sound coming from a speaker
(vibrations and waves)
PHYSICS
We need tostudy physics because it helps us understand how
the world works — and that understanding helps us solve
problems, build things, and improve our lives.
Here's why physics is important (in simple terms):
⚬ Explains everyday things
⚬ Helps create technology
⚬ Solves real-world problems
⚬ Trains your brain
14.
ELECTRIC FAN
• Useselectricity, motion, and energy conversion
• Electrical energy is converted into mechanical energy
• Spinning blades move air and help cool the body
15.
AIR CONDITIONER
• Usesheat transfer principles
• Removes heat from the room and releases it outside
• Makes rooms cooler and more comfortable
16.
COOKING
• Uses heattransfer: conduction, convection, and radiation
• Heat energy cooks food through direct contact, moving
fluids, or waves
• Makes food safe and ready to eat
17.
MICROWAVE OVEN
• Useselectromagnetic waves called microwaves
• Waves make water molecules vibrate and produce
heat
• Heats food quickly and efficiently
18.
WASHING MACHINE
• Usescircular motion, force, and energy
• Spinning motion removes dirt and water from clothes
• Makes washing faster and easier
• Learners formgroups of 4–5.
• Each group creates a chart/concept map
showing:
⚬ Household appliance/activity
⚬ Physics principle involved
⚬ How it improves quality of life

How would dailylife change if these
technologies did not exist?
