The Type of Liquid Used to Water Basil Plants Affects Their Height 11/20/08-12/18/08
Experiment Done by the following students from 6J: Max, Jacob, and Louisa
Our hypothesis in this experiment was that the type of liquid being watered on a basil plant affects its height.
For this experiment we had two Sweet Basil plants. At the beginning, they were both watered with water. We labeled one of the plants polluted, and the other non-polluted. Once the polluted plant started to grow, we watered it with half vinegar and half water. The experimental set-up and photos are in this link.
Materials and Methods
Materials
· 12 sweet basil seeds
· Two 331.6625cm3 clay pots
· 0.79 non-fertilized liters soil
· Up to 0.9 liters Heinz processed White Vinegar
· Up to 3.4 liters water
· Ruler
· Measuring cups/measuring pitcher
· 2 clay saucers
To do the experiment we followed this Procedure…
1. We filled both pots with 0.39 liters of potting soil.
2. We then planted 6 seeds in each pot, around 1.27 cm apart and around .32 cm down.
3. We watered each plant with 0.06 liters of water every day.
4. We measured them with a ruler and recorded the height of plant on every Monday.
5. We repeated steps 3 and 4 until the plants started to grow.
6. Then we watered one plant with 0.06 liters water and the other with 0.03 liters vinegar and 0.03 liters water.
7. We repeated steps 4 and 5 until the end of the experiment.

Lessons Learned
- acidic liquids are harmful to plants.
- if acidic liquids get into the soil where plants are it will affect their growth in a negative fashion.
- happens because acid deprives the plant of the nutrients that it needs, which would probably kill them.
- water helps plants grow, because water is a necessary ingredient in photosynthesis, which feeds plants.

Do not upload all of these documents. You should actually copy and paste onto the page. If someone viewed this page, he/she may not spend the time to view all of these documents.

table and graph need a lot of work--either check the page about tables and graphs on this wiki or the documents on moodle

Max and Louisa need to pull their weight. Both of you need to make the revisions listed above.

materials list: type of soil?
get pictures, tables, graph and experimental set up on this page, not as links.
not called conclusion
more bullets in lessons learned with brief explanations
get rid of "awesome" as a tag.

warm feedback-
very detailed
the experiment was designed well
the lessons learned section was informative

cool feedback-
no results
no point in table
not colorful enough-doesn't jump off the page
should have more lessons learned

Yes, I know about the data table, it doesn't work for me. I don't know why (I didn't read the instructions).

I think its cool that you used basil seeds, did you try eating them? haha
It won't let me see the pictures, but I want to see how the acidic liquid affected the plants. There's no data table or graph so I don't know whether they didn't grow at all or if the acids just made them grow less or become deformed.

warm: Interesting choice of plant. Good lessons learned.
Cool: But, I don't think that the experiment was very constant because you added the vinegar in the middle. I don't understand the introduction, what made the plant polluted and why did you suddenly add vinegar to the polluted one?
