These factors interact in complex ways to create a habitable environment on Earth. The unique combination of these conditions makes our planet an oasis of life in the cosmos and underscores the significance of preserving and protecting the delicate balance that sustains life on Earth.
1. RECALL:
• What do we call to a giant cloud and gas
in space that can take many different forms
and shapes?
• What do you call to the massive star
explosion?
• Can you name the eight planets in our solar
system?
3. Let us answer the Following:

• Who are the characters of the story?
• What was Goldilocks looking for in the bears’
house?
• Why did Goldilocks want something that was 'just
right'?
• what is common among the choices made by the
goldilocks?
4. GOLDILOCK ZONE
According to NASA:
The standard definition for a
habitable planet is one that can
sustain life for a significant
period; based on our solar
system, life requires liquid
water, energy, and nutrients.
A "habitable zone" is the region
around a star where planets
can receive the perfect amount
of heat to maintain liquid water
on their surfaces

6. Learning Objectives:
1. Identify and explain the factors that make Earth
unique and habitable
2. Explain the different factors that make Earth
unique and habitable
3. Recognize the factors that make Earth habitable
and appreciate important value and protect
our natural environment.
7. EARTH
The third planet from the sun and fifth largest in the
solar system
A terrestrial planet located in the Goldilock Zone (
habitable Zone)
Has unique physical and chemical characteristic
compare to other neighboring planets
The only habitable planet know in the solar System
that can support Life.
8. Group Activity
Each group will brainstorm and share their initial thoughts
on factors that make planet Earth habitable
Each group will create a list of the ideas they came up with
during their brainstorming session. Then, each group will
organize their ideas into a mind map format that visually
represents the factors that contribute to Earth's habitability.
Each group will use paper and markers or digital tools for this
task.
Each group present their findings.
Each group will do the task for 15 minutes:
11. Temperature
Influences how quickly atoms &
molecules move
Life seems limited to a temperature
range of -15oC to 115oC. In this range,
liquid water can still exist under certain
conditions.
12. Yearly surface temperature compared to the 20th-century average from
1880–2022. Blue bars indicate cooler-than-average years; red bars show
warmer-than-average years. NOAA Climate.gov graph.
13. Water
Dissolves & transports chemicals within
and to and from a cell
Water is regularly available. Life can go
dormant between wet periods, but,
eventually, water needs to be available.
14. According to Study of WHO:
In 2021, over 2 billion people live
in water-stressed countries,
which is expected to be worse
problem in some regions as result
of climate change and population
growth.
In 2022, globally, at least 1.7
billion people use a drinking
water source contaminated with
feces. Microbial contamination of
drinking-water as a result of
contamination with feces poses
the greatest risk to drinking-water
safety.
15. Atmosphere
Earth's atmosphere is composed of
several gases, primarily nitrogen (about
78%) and oxygen (about 21%). The
remaining approximately 1% includes
trace gases
Traps heat, shields the surface from
harmful radiation, and provides chemicals
needed for life, such as nitrogen and
carbon dioxide.
Earth & Venus are the right size to hold a
sufficient-sized atmosphere. Earth’s
atmosphere is about 100 miles thick. It
keeps the surface warm & protects it from
radiation & small- to medium-sized
meteorites.
16. Strong El Niño expected to drive
record-breaking global surface
temperatures and trigger climate crises
in 2023–2024.
• This phenomenon will lead to a
rapid increase in Global Mean
Surface Temperature (GMST), a
crucial climate indicator. The study
predicts a 17% chance that 2023's
GMST will be the highest since 1950,
rising to 56% in 2024.
• These extreme temperatures will
likely trigger various climate crises,
including marine heat waves,
reduced oceanic diversity, sea level
rise, and crop yield reductions.
17. Energy
Organisms use light or chemical
energy to run their life processes.
With a steady input of either light
or chemical energy, cells can run
the chemical reactions necessary
for life.
18. More Filipinos facing hunger in 2nd
quarter 2023
• Study found that 10.4 percent of
Filipino families experienced
“involuntary hunger” at least once
between March to June 2023.
• The figure was higher than March
2023’s 9.8 percent but lower than
December 2022’s 11.8 percent.
• The agency defines involuntary
hunger as “being hungry and not
having anything to eat.”
• The research was conducted from
June 28 to July 1, 2023
19. Nutrient
Used to build and maintain an
organism’s body
All solid planets and moon have the
same general chemical make up, so
nutrients are present.
Those with a water cycle or volcanic
activity can transports and replenish
the chemicals required by living
organisms.
20. Child alert: Severe wasting
Also known as severe acute malnutrition, severe
wasting is an overlooked but devastating child
survival emergency.
• Severe wasting, a deadly form of
undernutrition, poses a major threat to child
survival, causing 1 in 5 deaths among children
under 5.
• It results from lack of nutritious food and
diseases like diarrhea, measles, and malaria,
compromising a child's immunity. Despite
affecting 13.6 million children globally, severe
wasting is often overlooked.
• Ongoing conflicts, climate emergencies, and
the war in Ukraine exacerbate the situation,
plunging the world into a food crisis. Child
wasting has risen significantly, Immediate
action is crucial to prevent child deaths from
severe wasting.

Editor's Notes
Goldilocks was looking for something that was just right in the bears' house. Specifically, she tried out the porridge, the chairs, and the beds, looking for items that were neither too hot nor too cold, too big nor too small, and too hard nor too soft.
'just right' Goldilocks wanted to find the perfect fit for her.
Goldilocks' choices reflect the universal human desire for things that are just right
Can sustain life for a significant period" means having the right conditions that allow living things to exist and thrive over a long time.
The Earth's physical characteristics include its solid surface made up of land and water (such as oceans and seas), its atmosphere composed of gases (including oxygen and nitrogen), and its diverse landscapes like mountains, deserts, and forests.
In terms of chemical characteristics, Earth has a unique blend of elements and compounds. Water, a vital chemical for life, is found in abundance in the form of oceans, rivers, and lakes.
Influences how quickly atoms & molecules move means it affects how fast tiny particles, such as atoms and molecules, are in motion. This influence can be due to factors like heat, pressure, or energy, which determine the speed and behavior of these particles.
living things, as we know them, can survive and function best within temperatures ranging from -15°C (5°F) to 115°C (239°F). Within these temperatures, water can be in its liquid form, which is crucial for life processes
In summary, temperatures below -15°C can lead to cold stress and potential harm to living organisms. Water exposed to these temperatures will freeze, posing challenges for the survival of life forms that depend on liquid water.
In summary, temperatures above 115°C can cause heat stress, denaturation of proteins, dehydration in living organisms, and rapid boiling and evaporation of water, making the environment inhospitable for most life forms
Based on data from the National Centers for Environmental Information
Visual representation tell us of how our planet's temperature has varied over time, indicating cooler and warmer periods compared to what was typical in the 1900s.
means that water help breaks down substances into smaller particles and carries them within a cell or between cells. This process is vital for various cell functions, enabling essential chemicals to be moved to where they are needed and facilitating communication and cooperation among cells in the body.
means that in certain environments, there are regular periods of wetness where organisms have access to water. However, for life to sustain itself, water must eventually be present, as it is crucial for basic biological processes. Without water, life cannot function or survive in the long term.
In essence, it highlights a growing global concern where many people are experiencing water shortages, and this situation may become more severe in the future due to environmental and population factors.
Traps Heat: Earth's atmosphere acts like a blanket, trapping some of the sun's heat. This natural greenhouse effect keeps our planet warm enough for life to thrive.
Shields from Harmful Radiation: The atmosphere protects us by blocking harmful solar radiation, including dangerous ultraviolet rays. This shield is crucial for our well-being and health.
Provides Essential Chemicals: The atmosphere contains gases like nitrogen and carbon dioxide. Nitrogen is crucial for proteins and DNA in living organisms, while carbon dioxide is vital for plants to grow through photosynthesis, forming the basis of the food chain.
According Researchers from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences. Published on SEPTEMBER 28, 2023
All living things, such as plants and animals, rely on energy to carry out activities like growing, moving, and reproducing. Some organisms, like plants, use light energy from the sun through a process called photosynthesis. energy is essential for all living organisms to function and survive.
means that cells, the basic units of living organisms, need a constant supply of energy to perform the chemical reactions required for life processes.
This energy can come from sources like sunlight or specific chemicals. With this energy, cells can carry out functions like metabolism, growth, and
reproduction, allowing living organisms to sustain themselves and thrive.
energy is like fuel for cells, enabling them to perform vital tasks essential for life.

means these families experienced situations where they were hungry and didn't have anything to eat. The percentage was higher than March 2023's 9.8 percent but lower than December 2022's 11.8 percent. indicating the prevalence of this issue during that time period in Filipino households.
means that certain substances or materials are essential for constructing and sustaining the physical structure of living beings. These substances are used by organisms to grow, repair damaged tissues, and carry out various bodily functions. In essence, they are the building blocks that make up and support an organism's body, allowing it to function properly and stay healthy.
Examples:
Proteins: Essential for building muscles, enzymes, and various structural components in the body.
Carbohydrates: Provide energy for bodily functions and physical activities.
means they contain nutrients. Planets and moons with processes like water cycles or volcanoes can move and renew these chemicals. This movement provides the essential elements needed by living organisms, making these places potentially suitable for life.
Examples:
Silicon (Si): Found in rocks and minerals, including silicates.
Oxygen (O): Present in rocks, water, and various oxides.
Iron (Fe): Abundant in planetary cores and mantle materials.
Calcium (Ca): Found in minerals like calcite and gypsum..
Hydrogen (H): Found in water molecules and hydrocarbons.
