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? (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) Problem # 1 Independent Variable Number of tuba-tuba stems and their length (wala na ni labot, this is an extraneous variable) Level of water salinity (or simply salinity) Problem # ____ Independent Variable submarginal area. (please make sure that this idea is included in your RRL) Dependent Variable Variable Description (level of measurement , continuous/discrete) Number of leaves Discrete Plant Growth Continuous Length of the roots Continuous *you failed to note whether the level of measurement is nominal, ordinal, ratio or interval Dependent Variable Variable Description (level of measurement , continuous/discrete) Extraneous Variable Sunlight Weather Level of chlorine in the water (and other dissolved minerals also) Temperature of the water Variety of tuba-tuba Soil minerals/fertilizer… 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 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.) Quantities measured Control Less than 5ppm 5ppm More than 5ppm 10 tuba-tuba 10 tuba-tuba 10 tuba-tuba 10 tuba-tuba Number of leaves (date and time) 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. 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 (you may also use the test on correlation if you want to determine if the salinity has an effect on the factors you mentioned above) ANOVA Data Needed Mean in each subjects. What would the data analysis mean? If there is a significant difference between the (state the characteristics here) control and the tuba-tuba that is exposed to a level of water salinity.
