Names: Amer Hussein M. Marsangca Megan Elizabeth B. Maglinte Determining The Tuba-tuba Resistance to Saline Water Statement of the Problem Previous Main Problem Is tuba-tuba a halophyte? Sub Problems 1. Can tuba-tuba withstand 5ppm level of water salinity? Objectives of the Study Previous Main Objective of the Study To know whether tuba-tuba is a halophyte or not. Revised (if necessary) To determine the level of water salinity can tuba-tuba withstand. 1. How will the increasing level of salinity affect the leaves and color of the specimen? 2. How will the increasing level of salinity will affect the growth of the specimen’s roots? 3. How will the level of water salinity affect the rate of leaves falling? Revised (if necessary) To determine the resistance of tuba-tuba to saline water. Minor Objectives of the Study 1. To be able observe the changes happening to the tuba-tuba plant while we apply different levels of salinity. 2. 3. 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 submarginal area. resist a significant level of salinity. Problem # 1 Independent Variable Number of tuba-tuba stems and their length Level of water salinity Problem # ____ Independent Variable Dependent Variable Variable Description (level of measurement , continuous/discrete) Number of leaves left Color of the leaves Growth of the specimen Length of the roots Discrete Continuous Continuous continuous Dependent Variable Variable Description (level of measurement , continuous/discrete) Extraneous Variable Sunlight Weather Level of chlorine in the water Extraneous Variable Scope and Limitations of the Study 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 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. PROBLEM # 1 Sampling Method Simple Random Sampling Explanation (why you chose this sampling method) There are no differences on a population on the same species of plant 6 half-gallon ice cream containers 6 tuba-tuba stems 5 chicken nets salt Beaker Triple beam balance faucet water At home Amer’s home Market :P Grocery Mercury drug store At school (borrow lang mi kajut) faucet 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. 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. Place one tuba-tuba stem on each container. Use chicken net to support the stem and prevent it from falling. Record the observations daily for 2 weeks. PROBLEM # __ Sampling Method (describe briefly your sampling procedure) Explanation (why you chose this sampling method) Materials need Where you can get these materials or how you can get this materials (you may include cost of this materials if they are expensive) 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.) Statistical Tools Problem No. 1. Statistical Tool (provide a brief explanation why you chose this statistical tool) Unpaired T-test Data Needed Mean in each subjects. What would the data analysis mean? If there is a significant different between the control and the tubatuba that is exposed to a level of water salinity.
