2. For further understanding about
living organisms characteristics and
their differences with non-living
things, let’s do observation
3. Observation Sheet
1. Observe the characteristics of some
things (can be plants, animals, or
things) near your school
2. Fill in the table below
put a positive sign (+) if the object
has the characteristics, and negative
sign (-) if it doesn’t have the
characteristics.

5. a. Movement
animals and humans movement can
be clearly observed
animals move from one place to
another place because they have
special organs
ex. A bird has wings and feet, fish
have fins to swim
6. • The movement of plants is very difficult to
observe, because its movement is very slow
and doesn’t cause any displacement.
• Plants move by growing
• Ex. The root is growing and extending into the
ground, stem tip grow toward the sunlight, a
flower bud opens when it blossoms.
7. b. Eat
• All living things need food
• But plants do not eat like animals, plants produce
organic matters as their food through
photosysnthesis, it’s called autotrophic
6CO2 + 6H2O C6H12O6 + 6O2 + Energy
Carbon Water chlorophyl Glucose Oxygen
dioxide
• Green plants need certain substances, such as
carbon dioxide from the air and water are taken
from the soil.
8. • That process will produce glucose, oxygen, and
energy.
• Animals need another organisms to be eaten, it
is called heterotrophic.
• Base on their kind of food, animal divided into
3;
1. herbivores : feed on plants only
2. carnivores : feed on animals only
3. omnivores : feed on both plants and
animals
9. c. Respiration / Breath
• All living things need oxygen to breathe.
• They inhale oxygen and exhale carbon dioxide
and water vapor.
• The inhaled oxygen is used to help the burning
process of nutrient, this process is called
oxidation.
• Oxidation produce energy which is used to
perform daily activities.
10. • The process of inhaling oxygen and exhaling
carbon dioxide and water vapor is called
respiration.
C6H12O6 + 6O2 6CO2 + 6H2O
• The kind of respiration organs are ;
1. Mamalians : lungs
2. Birds : lungs and air sacs
3. Fish : gills
4. Plants : stomata and lenticels
11. d. Irritability
• Living things are sensitive to changes that occur in
their surroundings.
• When we are on a mountain range, we feel cold.
This cold sensation is received by the sensory
receptors in our skin.
• A sensory reseptor is an instrument within the
body which is sensitive to stimulus
• Animals and humans have sensory receptors,
therefore they can see, hear, smell, taste, feel,
touch.
12. • Eyes are sensitive to light so that we can see,
• ears are sensitive to the vibration so that we
can hear,
• nose is sensitive to odor so that we can smell,
• tongue is sensitive to taste so that we can taste
food,
• skin is sensitive to hot or cold and to
pressure, touch and wounds
13. • Plants do not have sensory receptors to
receive stimuli, but they are sensitive to the
stimuli such as light, water, gravity, and
touch.
• Ex. Touch-me-not plant (Mimosa pudica)will
close its leaves when it is touched, shoots
will grow and bend toward the direction of
the light.
14. e. Grow and developed
• If we plant a seed, it will germinate. The sprout
will grow bigger and thicker.
• Chicken growth starts from a chick that hatched
from an egg, the chick then grow and become an
adult, hen or rooster.
• Human and animal growth will stop when they
reach a certain age.
• However, in plants, we will find that the forming
of buds, leaves and flowers, happen continuously
all their lives.
15. • Grow occurs because cells divide causing
them to be more numerous which causes
organisms to get bigger.
• Developed occurs when cells take on
specific jobs within the organism (like
heart cell or brain cell)
16. f. Excretion
• The process of removing metabolic waste in living
organisms is called excretion.
• Excretion organs in humans as follow ;
1. Lungs : CO2 and H2O vapor
2. Liver : excrete bile
3. Kidneys : urine
4. Skin : Sweat
• Excretion in seed plants occurs through the stomata
in the leaves and lenticels on the stems.
17. g. Reproduction
• Every living organism will produce its
own offspring, called reproduction.
• Every species has different methods
to reproduce, but the two main
methods are by asexual (vegetative)
and sexual (generative) reproduction.
