“Sunlight: Factor that
Affects Seed Germination”
Plants like animals reproduce to
increase their number and preserve
their kind. Some plants come from
seeds. Seeds need the right condition
to germinate. The amount of
moisture and sunlight, and the type
of soil are among the factors that
affect seed germinate.

Factors that

Problem:
What is the effect of
sunlight in seed germination?
Hypothesis:
If the sunlight is reached by the sunlight
then, it will sprouts or germinate healthy and it
will grow fast.
MATERIALS:
● 2 empty cans of the
same kind
● Humus or Garden
soil
●10 mongo seeds
● Water
Procedure:

Punch holes at the bottom of cans. Label them A and B.
Fill about three-fourths of each can with soil.
Plants 5 mongo seeds in each can.
Water the seeds in both set ups everyday of five days.
Place can A in an area reached by sunlight.
Place can B in an area not reached by sunlight.
Observe the seeds in both cans everyday for five days. Record your
observations in the table below.
Experimentation
Can A
with sunlight
Can B
Without sunlight
Result and Analysis:
Observation
Plant A
Plant B
Number of sprouts after five days
All the seeds that we planted grow
healthy.
All seed was grown but unhealthy
compared to the seed which is
reached by the sun.
Colour of the mongo sprouts
Yellow Green/ordinary color of the
sprout and its leaves seems to be
healthy.
The color of its leaves was yellowish
compared to the can A.
Size of the mongo sprouts
We observed the size of mongo sprout The size of mongo sprout were thin.
were ordinary and grows healthy and
Although it grows but it is
it grows bigger
unhealthyS.
Observation:
OBSERVATION
We, as a group we observed that in can A
which was reached by sunlight. The seeds
germinate naturally and healthy and the color of
the leaves was green. On the other hand, in can
B which was not reached by the sunlight the
sprouts of the mongo was unhealthy and the
leaves turn into yellowish color. It grows higher
but the sizes of its stem was thin.
Conclusion:
We concluded that the seeds need
sunlight in order to grow healthy. In
germinating seed, it is necessary to
expose in sunlight in order to grow healthy.
The temperature is also needed in
sprouting seeds.
Reflection
During our experimental period, we
learned about how the mongo seeds
grow. And the different factors
that affect the growth. Not only
that, but also we build a good
collaboration in order to finish our
experiments.
