     DO DIFFERENT TYPES OF LIQUIDS CHANGE THE
                                 GROWTH OF PLANTS?

                                      Introduction
       In our experiment, we are planting black bean seeds and we are going to see if the different types of liquid affects the growth of the seeds other than water. We have five different experiment groups. We will have a control group as water, A&W, kool aid with out added sugar, kool aid with added sugar, and sugar with water.


                                                       Purpose

         The purpose of this lab is to find out if different types of liquids will increase the growth of the plant.


                                            Hypothesis

         Our group thinks that sugar will negatively affect the growth of the plant.


                                             Materials

                                                         15 seeds
                                                         A&W
                                                         water
                                                         purple kool aid with added sugar
                                                         purple kool aid without added sugar
                                                         sugar
                                                         stirring rod
                                                         graduated cylinder
                                                         paper towels
                                                         pencil & paper
                                                         potting soil
                                                         cups
                                                         ruler

                                              Procedure

         1. Get the 5 cups for planting your seeds and poke a hole in the bottom of each one.
         2. Put potting soil in the 5 cups.
         3. Dig a hole in middle of the soil and put 3 seeds in each cup.
         4. Fold 3 paper towels into a square and put them underneath the cup (for each cup).
         5. Pour 80 mL of the liquids into different cups onto the seeds (every class day)
         6. record if the seeds are growing



                                                Observations & Data



After initial watering, we noticed a mold of some sort growing on the top of the root beer, sugar water, and undiluted Kool aid watered plants.



Upon further research, we found that the mold means that the plant is dead, so we will not be expecting much from those 3.



After collecting data for a few days, we had witnessed no growth in any of the plants except for the control, which had a very small sprout. this graph shows the growth rate of all the black bean seeds.




Data Analysis


After analyzing the data for the growth rate of the Root beer watered plant, this is the graph we compiled to show the growth rate:

                                                     

After analyzing the growth data of the Undiluted Kool Aid seed, this is the growth rate results:



Sugar water growth rate data:


Kool aid With sugar water added growth data:



Control water growth results:


Looking at all the data, all the plants appeared to have died except for the control plant, which had still grown significantly less than the expected 10 centimeters. 


Discussion



              After compiling all of the data we collected over the course of the week, we had no growth in our experimental seeds. 3 out of 4 of the seeds developed a mold with a horrible odor emitting from them. We had kept the soil fertilized with their respective water alternatives, with 80 ml, draining them immediately after to ensure not over watering, but properly moistening all of the soil. If our group had repeated this experiment, we would have used less water to fertilize the soil, probably somewhere around 40 ml of water rather than 80. We feel the overkill of water we used was detrimental to the growth rate of the plants. However, we feel if we had repeated this experiment with revised procedures, the experimental seeds would have still been killed by their water alternatives, or have seriously stunted growth.
