In our project scenario of story of the seed we hypothesized that different acidity levels would affect the germination and growth of broccoli seeds. As well as, In our indoor experiment for the Story of The Seed, we tested broccoli with the usage of different amounts of various vinegars which included malt and apple cider along with that, we added different measure of vinegar. For both the water and vinegars the different measures are 1/2, 1/4 and full. In our project we tested the hypothesis of, if different acidity levels affect the growth of plants, then giving vinegar to broccoli will affect the growth and germination of the broccoli seeds. To test this hypothesis we watered broccoli seeds with different levels of malt and apple cider vinegar. We also watered 3 broccoli seeds with only water for our constant variable. The overall result was that the broccoli that only had water was able to germinate. The vinegars had essentially sterilized the growth of the broccoli.
Methods
To start our project the materials you will need will be broccoli seeds, apple cider vinegar, malt vinegar, water, beakers, a measuring cup, and scale. Our project started by taking 15 planter pots in each pot we put approximately the same amount of dirt in each pot, and we measured it out by using the scale. After, we planted 3 broccoli seeds in each pot. From there we labeled each pot by the type of liquid we put into each pot. Therefore the first three pots were labeled water in yellow sticky notes. The pots with water were our control group. The next group was the malt vinegar group. Each pot was labeled with malt vinegar, and how much vinegar was put into each pot, so for the first one we put 100 percent malt vinegar. The next pot was 50 percent malt vinegar and 50 percent water. After the pot was 25 percent malt vinegar, and the rest being 75 percent water. The same goes for the apple cider vinegar the first pot 100 percent apple cider vinegar. The next 50 percent apple cider vinegar and the other 50 percent water. The last pot being 25 percent apple cider vinegar, and 75 percent vinegar. We watered the plants a total of 1 inches of liquid, or 25.4 millimeters of liquid After we labeled all the pots and marked them correctly according to how much vinegar, water, and most importantly what type of vinegar it was. We watered the broccoli plants once a week. After we waited to see how long it would take for the broccoli to grow. After 5 days our first broccoli grew. The first sprouted was from the control group. After about two weeks we were able to conclude the data from the experiment.
Results and Data Analyses
After 13 days, watering the plants every other day, and monitoring them we concluded that vinegar being added or substituted for water lowered the germination rate significantly. Not only did none of the seeds who received straight vinegar germinate, but only 2/6 of the control group germinated. It is not impossible that the plants needed more time, but unlikely.

Conclusions
In conclusion through our experiment 2 out of the 15 seeds we planted grew. The two plants that grew were from the control group. We can conclude that the control group was much healthier. Our total was 2/30 seeds germinating, which sends pretty clear results about the detrimental effect the vinegar had on the germination process.
In conclusion through our experiment 2 out of the 15 seeds we planted grew. The two plants that grew were from the control group. This shows that water is the best living conditions that broccoli can live in. Although since only two seeds sprouted out of three from the control group at the same time we can also conclude that further research should be done. We could achieve this by extending the period of time for the broccoli to grow, or we could wait until each broccoli plant is completely grown , and taste how each plant tastes, so we can determine which one grew better and tastes better. Also from our experiment we feel that if we had more of a broader time frame we could make distinct conclusions to our experiment. For example we could have waited until each plant grew and then make conclusions based on the height of each plant, and the width of each plant to further show which plants were growing better. Although I do think that we can still draw the conclusion that because 2 out of our 15 plants grew we can safely say that broccoli grows best in water rather than in malt vinegar, or apple cider vinegar.
