CONTENT OF THE LESSON
LESSON 1 – UNDERSTANDING WATER
WHAT IS WATER?
Water is a clear, colorless, odorless, and tasteless liquid that is essential for all life on Earth. It is made up of two hydrogen atoms and one oxygen atom (Hâ‚‚O).
IMPORTANCE OF WATER:
- All living things need water to survive
- Our bodies are about 60% water
- Used for drinking, cooking, cleaning
- Plants need water to grow
- Animals drink water to stay alive
- Used in industries and agriculture
LESSON 2 – DIFFERENTIATING WATER FROM OTHER LIQUIDS
Water has unique properties that make it different from other liquids we encounter daily.

- Water freezes to solid ice
- Other liquids may not freeze or freeze differently
LESSON 3 – EVAPORATION
WHAT IS EVAPORATION?
Evaporation is the process where water changes from liquid to gas (water vapor) when heated or exposed to air. This happens when water molecules gain enough energy to escape into the air.
HOW EVAPORATION HAPPENS:
THE PROCESS:
- Water molecules move constantly
- Heat gives molecules more energy
- Fast-moving molecules escape from liquid surface
- These molecules become water vapor (invisible gas)
- Water level decreases over time
CONDITIONS FOR EVAPORATION:
- Heat/Temperature: Higher temperature = faster evaporation
- Air Movement: Wind speeds up evaporation
- Surface Area: Wider containers evaporate faster
- Humidity: Dry air promotes faster evaporation
EXAMPLES OF EVAPORATION:
DAILY LIFE EXAMPLES:
- Wet Clothes Drying: Water evaporates from fabric
- Puddles Disappearing: After rain, puddles dry up
- Cooking: Steam rises from hot soup
- Sweating: Body water evaporates to cool us
- Wet Hair Drying: Water evaporates from hair
- Boiling Water: Rapid evaporation produces steam
NATURAL EXAMPLES:
- Rivers and Lakes: Surface water evaporates
- Ocean Water: Becomes water vapor in atmosphere
- Plant Leaves: Release water vapor (transpiration)
- Morning Dew: Evaporates as sun rises
FACTORS AFFECTING EVAPORATION SPEED:
FASTER EVAPORATION:
- Higher temperature
- More wind/air movement
- Larger surface area
- Lower humidity
- Higher altitude
SLOWER EVAPORATION:
- Lower temperature
- Still air
- Smaller surface area
- Higher humidity
- Sea level
SIMPLE EVAPORATION EXPERIMENTS:
Experiment 1: Different Temperatures
- Put equal water amounts in two containers
- Place one in sun, one in shade
- Observe which evaporates faster
Experiment 2: Surface Area
- Put equal water in wide plate and narrow glass
- Observe which evaporates faster
- Wide plate should evaporate faster
Experiment 3: Air Movement
- Put water container near fan
- Put another container in still air
- Compare evaporation rates
LESSON 4 – CONDENSATION
WHAT IS CONDENSATION?
Condensation is the process where water vapor (gas) changes back into liquid water when it cools down. This is the opposite of evaporation.
HOW CONDENSATION HAPPENS:
THE PROCESS:
- Water vapor in air cools down
- Cool water vapor molecules slow down
- Slow molecules stick together
- Form tiny water droplets
- Droplets collect on surfaces
CONDITIONS FOR CONDENSATION:
- Cooling: Water vapor must cool down
- Surface: Needs something to condense on
- Saturation: Air must be full of water vapor
EXAMPLES OF CONDENSATION:
DAILY LIFE EXAMPLES:
- Cold Drink Glass: Water droplets form on outside
- Bathroom Mirror: Fogs up during hot shower
- Car Windows: Fog forms on cold mornings
- Breath on Cold Day: Visible vapor from mouth
- Cooking Pot Lid: Water droplets form underneath
- Air Conditioner: Water drips from unit
NATURAL EXAMPLES:
- Clouds Formation: Water vapor condenses in sky
- Dew on Grass: Forms on cool morning surfaces
- Fog: Water vapor condenses near ground
- Rain Formation: Condensed water falls as raindrops
WHY CONDENSATION OCCURS:
TEMPERATURE DIFFERENCE:
- Warm water vapor meets cool surface
- Cool surface causes vapor to condense
- Greater temperature difference = more condensation
HUMIDITY LEVELS:
- High humidity = more water vapor in air
- More water vapor = more condensation possible
- Low humidity = less condensation
SIMPLE CONDENSATION EXPERIMENTS:
Experiment 1: Cold Glass
- Fill glass with ice-cold water
- Observe water droplets forming on outside
- Touch droplets to confirm they’re water
Experiment 2: Breath Condensation
- Breathe on cold mirror or window
- Observe fog formation
- Watch fog disappear as it warms
Experiment 3: Pot Lid
- Boil water in pot with lid
- Lift lid carefully (adult supervision)
- Observe water droplets on lid underside
LESSON 5 – FREEZING
WHAT IS FREEZING?
Freezing is the process where liquid water changes into solid ice when its temperature drops to 0°C (32°F) or below.
HOW FREEZING HAPPENS:
THE PROCESS:
- Water temperature drops to 0°C (32°F)
- Water molecules slow down significantly
- Molecules arrange in orderly pattern
- Water becomes solid (ice)
- Ice is hard and rigid
FREEZING POINT:
- Pure water freezes at exactly 0°C (32°F)
- Salt water freezes at lower temperature
- Sugar water also affects freezing point
WHAT HAPPENS WHEN WATER FREEZES:
PHYSICAL CHANGES:
- State Change: Liquid becomes solid
- Volume Increase: Ice takes up more space than water
- Shape: Takes shape of container
- Hardness: Becomes hard and rigid
- Temperature: Stays at 0°C during freezing
IMPORTANT PROPERTY:
- Water expands when it freezes
- This can break containers (pipes, bottles)
- Ice floats on water because it’s less dense
EXAMPLES OF FREEZING:
DAILY LIFE EXAMPLES:
- Ice Cubes: Water frozen in freezer
- Ice Cream: Contains frozen water
- Frozen Foods: Water in food becomes ice
- Ice Pops: Flavored water frozen on stick
- Frost: Water vapor freezes directly on surfaces
NATURAL EXAMPLES:
- Lakes and Rivers: Freeze in cold weather
- Icicles: Water drips and freezes hanging
- Snow: Frozen water vapor in clouds
- Hail: Frozen raindrops
- Frost on Windows: Direct vapor to ice
USES OF FROZEN WATER (ICE):
PRACTICAL USES:
- Food Preservation: Keeps food fresh longer
- Cooling Drinks: Makes beverages cold
- Medical Uses: Ice packs for injuries
- Recreation: Ice skating, ice sculptures
- Transportation: Ice roads in Arctic regions
SIMPLE FREEZING EXPERIMENTS:
Experiment 1: Basic Freezing
- Fill ice cube tray with water
- Put in freezer for 2-4 hours
- Observe solid ice formation
Experiment 2: Expansion Test
- Fill plastic bottle completely with water
- Put in freezer overnight
- Observe how bottle expands or cracks
Experiment 3: Melting and Refreezing
- Take ice cubes out of freezer
- Watch them melt at room temperature
- Put liquid water back in freezer
- Observe refreezing process
LESSON 6 – THE WATER CYCLE CONNECTION
All three processes (evaporation, condensation, freezing) work together in nature:
WATER CYCLE STAGES:
- EVAPORATION:
- Sun heats ocean, lake, and river water
- Water vapor rises into atmosphere
- CONDENSATION:
- Water vapor cools in upper atmosphere
- Forms clouds and water droplets
- PRECIPITATION:
- Condensed water falls as rain
- In cold weather, may freeze and fall as snow
- COLLECTION:
- Water returns to rivers, lakes, oceans
- Cycle begins again
SEASONAL CHANGES:
SUMMER:
- More evaporation due to heat
- Less freezing except in refrigerators
- More condensation on cold drinks
WINTER:
- Less evaporation due to cold
- More freezing (ice, snow, frost)
- More condensation indoors (heating systems)

LESSON 2 – WHAT IS PROGRAMMING?
DEFINITION OF PROGRAMMING:
Programming is the process of creating computer programs. It involves writing step-by-step instructions in a special language that computers can understand and follow.
KEY ASPECTS OF PROGRAMMING:
- PROBLEM SOLVING
- Identify what problem needs to be solved
- Break big problems into smaller parts
- Think logically about solutions
- Plan step-by-step approach
Example Problem: Create a program to add two numbers
- Step 1: Ask user for first number
- Step 2: Ask user for second number
- Step 3: Add the two numbers together
- Step 4: Show the result
- WRITING CODE
- Use programming language to write instructions
- Follow specific rules and grammar (syntax)
- Write clear, understandable commands
- Test that code works correctly
Simple Example Code (in English-like form):
START
DISPLAY “What is your name?”
GET name FROM user
DISPLAY “Hello, ” + name + “!”
END
- TESTING AND DEBUGGING
- Run the program to see if it works
- Find and fix errors (called “bugs”)
- Make sure program does what it’s supposed to do
- Improve the program to work better
