CRITERIA B, STRAND 1: QUESTION
Question:
I am yearning to investigate that how does different classifications of soil(garden soil, sand,
succulent soil, black soil and lane soil, independent variable) affects the growth(height, dep endent
variable) and the germination of the mung beans seed?
Significance of the question/purpose:
To investigate the interrelationships between the types of soil to the aggrandizement (height) and
germination of a plant and different soil’s precipitate on a type of plant.

you are thinking of growing plants
in sand, consider growing
succulents like cacti, sedum, lamb's

lavender, or euphorbia species.
There are also sand-loving trees
and grasses to consider.

how does type of soil affect seed
growth?
Optimal soil temperature and
soil moisture conditions are
necessary for a favorable
germination.
In the field an ideal
combination of soil temperature
and soil moisture seldom
occurs. The soil moisture
tension curve gives an idea of
the suitability of water and air
(figure 1). For example in a
moist zone between pF 0.5 and
2.0 optimal germination can be
affected by seed rotting or toxic
material rinsed out of the seed.

How important is the organic
matter in the soil?
In addition to providing
nutrients and habitat to
organisms living in
the soil, organic matter also
binds soil particles into
aggregates and improves the
water holding capacity of soil.
Most soils contain 2-10
percent organic matter.
However, even in small
amounts, organic matter is
very important.

Hypothesis:
If mung beans were implanted to pots with the soil above to see the heightening of the plant, then
the beans planted with the lane soil will grow the preeminent amongst the rest of the soil, because

cadaverous insect’s body that the roots of the beans are more able to ingurgitate nutritions from

precipitancy of fertilization of the plant, ergo, the lane soil will dilate the most towering plant.

Spill of redundant water
Water the plants carefully so the
water won’t be flooding
Grab a cloth or sponge to wipe the
water in the nearby sink slowly and
call an Ayi to clean the waters on
the ground. Remove the extra water
into the sink, careful not to let the
plant falls in the sink. Leave after
making sure the place is dry.
Big mess of soil
Shovel the soil careful to the pot,
don’t shovel too much at a time.
Grab a cloth with water and wipe
the dirt to a rubbish bin, call an Ayi
if the scene is too much messed up.

Garden soil: The withered cotyledons are on the middle of the stem. The hypocotyl of
both plants are slightly red. The stems are short but sturdy. The two leaves are a little bit
curled up.
Sand: The seedlings are short but sturdy, the hypocotyl is rich of water and just like
garden soil, it is slightly red.
Succulent soil: None of the beans were geminated, but rather turns moldy.
"The independent variable: different types of soil
The dependent variable: height of the plants:”
The independent variable, types of soil, affects the dependent variable, height of the plant:
The data shows that amongst the independent variables, the plant with the highest
dependent variable goes to the black soil by the number of plant one nineteen centimeters
and plant two fifteen centimeters, followed by loam soil of eleven centimeter, however,
only one plant was germinated in loam soil. The garden soil, given the height of ten and
eight point one, was ranked number three. Sand is seven and four centimeters, on the
fourth place. The succulent soil, in the last place, haven’t even germinated: both seeds
were found moldy in the soil.
Noteworthy trends: In the garden soil and the sand soil, something interesting is
happening: both of the plants, their hypocotyl are both slightly red. This probably because
of the ferric/iron in the soil.
CRITERIA C, STRAND 3:
Validity of the hypothesis based on the outcome of the scientific investigation:
The original hypothesis:
Page 10 of 13
Lab Report
“If mung beans were implanted to pots with the soil above to see the heightening
of the plant, then the beans planted with the lane soil will grow the preeminent amongst
the rest of the soil, because the lane accommodate many decomposable and organic
substantiality such as fall leaves, cadaverous insect’s body that the roots of the beans
are more able to ingurgitate nutritions from amongst the rest of the pots, which will
presumptively proliferate the elevation and the precipitancy of fertilization of the plant,
ergo, the lane soil will dilate the most towering plant.”
Do the experiment of the result support or rejects this very hypothesis?
The experiment does not support the hypothesis, since the black soil has the largest
dependent variable, which we previously predicted the result would be loam soil in the
hypotheses.
In the final data, the average height for the seedlings in the black soil is six centimeters
higher than the loam soil. One of the loam soil seed haven’t even germinated and goes
moldy in the pot. Clearly, the hypotheses failed.
I think this is because that we over underestimated the fertility of the black soil:
Black soil, AKA chernozems, contains nearly all 17 essential nutrients for proper growth of
the plant.
The water (moisture) Holding capacity and number of voids is more in the black soil than other
soil which provides sufficient quantity of water for a longer period of time. That means black soil
retains water for longer periods also provides is effectively.
According to Wikipedia(Chernozem. (2004, February 27). Retrieved June 4, 2019, from
https://en.wikipedia.org/wiki/Chernozem), Chernozem is a black-colored soil containing a high
percentage
of
humus(4%
to
16%)
and
high
percentages
of phosphoric
acids, phosphorus and ammonia. Chernozem is very fertile and can produce high agricultural
yields with its high moisture storage capacity. Chernozems are also a Reference Soil Group of
the World Reference Base for Soil Resources (WRB).

I could improve the method by making it more brief and easier to follow, cut the redundant

a lot better if more types of soil(IDV) are added, for instance, red soil or volcanic soil, to
test their fertility on plants.
