Determining The Tuba-tuba Resistance to Saline Water
Statement of the Problem
Previous
Main Problem
Is tuba-tuba a halophyte?
(you can still use this as your main problem)
Sub Problems
1. Can tuba-tuba withstand 5ppm
salinity?
(why did you choose 5ppm gani?... iremove na
lng ni…)
Objectives of the Study
Previous
Main Objective of the Study
To know whether tuba-tuba is a halophyte or
not. (replace know with determine)
Revised (if necessary)
Is tuba-tuba a halophyte?
1. Can tuba-tuba withstand 5ppm
salinity?
2. How will the increasing the salinity
affect the leaves and color of the
specimen? (I suggest you replace this
with growth of the plant na lng
because its easier to measure)
3. How will the increasing the salinity
affect the growth of the specimen’s
roots?
Revised (if necessary)
To determine the resistance of tuba-tuba to
saline water. (ayaw na ni)
Minor Objectives of the Study
To determine the effects of varying
salinity on the number of leaves and the
growth of roots of the tuba-tuba plant.
Hypothesis of the Study (only those which requires statistical tools/proofs)
Hypothesis Statement
Theoretical Basis/Support
Since tuba-tuba is a plant that
We have read in the internet that tuba-tuba is a plant which
can withstand a wide range of
can withstand a specific level of aridity and can live in
environment, it may be able to
resist a significant level of
salinity. (replace resist with
tolerate)

Number of tuba-tuba
stems and their length

is an extraneous
variable)

Extraneous Variable
 Sunlight
 Weather
 Level of chlorine in
the water (and other
dissolved minerals
also)
 Temperature of the
water
 Variety of tuba-tuba
 Soil

diba you will use
hydroponics?
Extraneous Variable
Scope and Limitations of the Study (check tenses)
The research will be focusing on the determination of the ability of the Tubang Bakod to resist
particular levels of salinity. The research shall be conducted in local areas (specify the locality) and the
effect of the present environment to the specimen shall not be included in our research. Faucet water
shall be utilized in our research and the chlorination of the water shall not be included in the proposed
research. The research shall be conducted regardless of what weather is present since we have limited
time. (I thought you will use hydroponics…you should mention that fact here…including what kind of
fertilizer you will be using and the design of your hydroponics set-up)
PROBLEM # 1
Sampling Method
Explanation (why you chose this sampling
method)
There are no differences on a population on the
same species of plant
Simple Random Sampling
6 half-gallon ice cream containers
6 tuba-tuba stems (there should be more than 6)
5 chicken nets (what size?)
salt
Beaker
Triple beam balance
faucet water

Experimental Set-up (May be presented using a table or a diagram. Please explain briefly why your
design is such.)

Experimental Procedure (May be in paragraph, bullet or flow chart.)



Gather 6 tuba-tuba stems approximately 45 cm. from the base, place them on a temporary
container until roots start to grow. (not clear…cut the stems 45m from the base?... temporary
container is not clear… how do you prepare a temporary container? )
Fill each of the six half gallon icecream container with 2 L of faucet water.
In each of five containers, add a specific amount of salt depending on the level of salinity the
container is assigned to. One will not be added with salt for that is where the control will be
placed. (use a table to present how much salt will be added per container and the corresponding
salinity of each container)



Place one tuba-tuba stem on each container.(your results would be inconclusive if you base your
conclusion on 1 plant per concentration only)
Use chicken net to support the stem and prevent it from falling. (how will this look like? Provide
a diagram ha?)
Record the observations daily for 2 weeks.
*please learn more about hydroponics… if you seriously want to use it you should do some revisions in
your set-up and in your materials.
