A
BSTRACT
Practical projects play a significant role in studying natural sciences. Linking theory with practice facilitates
easier comprehension and retention of topics. For instance, examining the internal structure of a bean seed
and observing its germination process in experiments can spark students' interest in science and develop
their experimental skills. Additionally, such projects are beneficial in preparing students for life, teaching
them to work systematically and according to plans.

NTRODUCTION
In teaching natural sciences, incorporating topic-
related experiments leaves a strong impression
on students. Practical application of knowledge
ensures lasting understanding, as theoretical
knowledge alone may fade without reinforcement
through practice. Increasing the number of
practical lessons is therefore crucial. These
lessons can utilize easily available and commonly
used materials.
One example of project work could involve
studying the external and internal structure of a

bean seed and the factors affecting its
germination.
For this project, the following steps are planned:
1.
Measuring the length of a dry seed.
2.
Measuring the length of a soaked seed.
3.
Observing the internal structure of the
seed using a magnifying glass.
4.
Identifying the conditions necessary for
seed germination.
5.
Monitoring the growth processes of beans
in normal conditions.
The bean is an annual herbaceous plant whose
seeds mature inside its pod. Bean seeds are
commonly consumed in salads or as part of meals.
Rich in nutrients and vitamins, bean seeds are
particularly high in proteins and B-group
vitamins, which enhance memory.
How do we study the structure of a seed?
The following experiment outlines the process:
Materials Needed:
•
Bean seeds
•
A glass of water
•
White paper
•
A ruler
•
A magnifying glass
Procedure:
1.
Take 10 bean seeds.
2.
Measure the length of each seed and
calculate the average length of the 10 seeds.
3.
Place the seeds in a glass of water.
4.
After one day, measure the length of the
soaked seeds and calculate their average length.
5.
Determine how much the seeds have
increased in size by subtracting the average

length of the dry seeds from the average length of
the soaked seeds.
6.
Peel the seed coat off the soaked seeds and
separate the cotyledons.
7.
Locate the embryo.
8.
Observe the structure of the embryo using
a magnifying glass.
9.
Record your observations in your
notebook.
•
What changes occurred when the seeds
were soaked?
•
By how many centimeters did the length of
the seeds increase after soaking?
What are the parts of a seed?
To determine this, we observe the seed using a
magnifying glass. The seed consists of three main
parts:
Seed Coat: Protects the seed from drying out.
Two Cotyledons: Store nutrients.
Embryo: Develops into a new plant.
Experiment on Studying the Germination Process
of a Seed
To study the conditions necessary for bean seed
germination, a plan is created consisting of the
following steps:
1.
Study the conditions required for
germination.
2.
Observe the germination process of
soaked and unsoaked seeds.
3.
Record daily observations in a notebook.
4.
Grow beans in light and dark
environments and monitor changes.
5.
Draw conclusions based on the results.
Materials Needed

Paper towels
•
Spray bottle
•
Plastic containers
•
Stretch wrap
•
Soil
Procedure
1.
Soak 10 bean seeds in a glass of water for
one day.
2.
Place paper towels in two containers.
3.
In one container, place 5 soaked seeds; in
the other, place 5 unsoaked seeds.
4.
Cover the seeds with a paper towel and
moisten them using a spray bottle.
5.
Cover the containers with stretch wrap
and poke small holes for ventilation.
6.
Keep the containers in a warm place.
7.
Observe and record changes daily in your
notebook.
8.
Once the seeds develop roots, stems, and
initial leaves, add soil over the roots to cover
them.
9.
Place one container in a bright location
(e.g., near a window) and the other in a dark space
(e.g., a cupboard).
10.
Spray water on the seeds daily.
11.
Monitor the plants for 10 days.
12.
Compare and record the changes observed
in both conditions.
13.
Write the results in your notebook and
draw conclusions
Day 1. Formation of the root.

Carrying out experiments as project work by each
student increases their interest in science and
helps develop their skills in conducting
purposeful experiments. Drawing conclusions
based on the experiments strengthens the
students' acquired knowledge.
These experiments were conducted by students
of grades 2, 5, and high school. The assignments
were gradually made more complex according to
the students' age. The experiments sparked great
interest among students of all age groups, with
the main differences lying in the conclusion
phase. By studying the structure of seeds,
observing the germination process, and testing it
in practice, students developed skills to apply
their knowledge in real-life situations.
