| Explore | Hello, I’m Luke, I’m not very fond of planting. Some plants are tasty and some make me breathe so I'm ok with plants. Hello, I’m Jazzlyn, I have a good amount of experience with planting. My family and I don’t exactly have a farm but you could consider it. We have multiple vegetable... |

| Research Question | Can corn grow if watered with water that has salt dissolved in it? We are interested to help agriculture in areas with less rainwater and more brackish water. We hope to figure out a solution for this problem by asking this question and testing it. |
| Predictions | We think that the roots will shrivel up and rot in the 0.8g salt concentration, it will not grow as big or as fast as it would in the 0.4g salt concentration, and it will grow pretty well in the .1g salt concentration. We think that the control with no salt will grow the best. These... |
| Experimental Design | Materials: Salt: .8 times three=2.4 .4 times three=1.2 .1times three=.3 12 pots ¾ cup of soil per pot (times twelve)=nine cups sixty corn seeds-five per pot 39 grams of salt Steps: Step 1: Put 3/4 of a cup of soil into a pot and plant 5 corn seeds 2 inches down, spread 2 centimeters... |
| Conclusion | The data we collected partially supports our prediction. We thought that the roots would shrivel up and rot in the 0.8 g salt concentration, it would not grow as big or as fast as it would in the 0.4 g salt concentration, and it will grow pretty well in the .1 g salt concentration. We think that... |

The students was passionate about their experiment. The students and mentor discussed about their experiment everyday. The students asked questions and updated their progress daily to their mentor. This team made great communication with the mentor by updating their work process and data.... |
Updates
Dear Dragon Blood Trees -
Please give yourselves a round of high fives for bringing your project to a successful conclusion. You overcame some difficult initial problems and decisions and then really got busy figuring things out as you went through the experiment. I was impressed with your postings to this website, which were among the most literate I have seen in years. I greatly enjoyed meeting you by Zoom, and I wish there had been more time to have additional meetings towards the middle and end of the project.
Best wishes for a happy Thanksgiving and a successful completion of this first half of the school year.
Yours sincerely,
Andrew Schnabel
Farewell and Best Wishes
As this research project is now in the final stages of wrapping-up, we wish to thank everyone who participated in this inquiry; the students, mentors, teachers and others behind the scenes. We appreciate all of your efforts and contributions to this online learning community.
Scientific exploration is a process of discovery that can be fun! There are many unanswered questions about plants just waiting for new scientists to consider, investigate, and share.
After the end of the session, we will be updating the platform and archiving groups and projects, after which time new updates/posts will not be able to be added to projects or groups. You have until Friday, November 19, 2021, to post ALL of your updates, comments, and goodbyes. Please come back and visit the PlantingScience Project Gallery anytime to view this project in the future. You can search the Gallery by keyword, team name, topic, or school name.
Good bye for now.
Warm regards,
The PlantingScience Team
Hello, thank you so much for your help and advice. P.S we are making a presentation next week. From the Dragon Blood Tree's
Dear DBTs -
Thanks for uploading those photos of your graphs. I have three suggestions/questions:
1) For the height data, I think the line graph is more successful than the bar graph. It's easier to read - to see the differences between treatments.
2) Also for the height data, is there a way in your graphing program to make the x-axis give the number of days after planting rather than the date. For example, if you planted on 10/8 and took your first data on 10/14, then you could call 10/8 day 0 and 10/14 day 6. Then you would count the days from day 0 and plot your x-axis a continuous variable between 0 and 21 (three weeks from planting). I'm suggesting this, because the measurements were not evenly spaced in time - some were two days in row and some were a week apart. The plants have more time to change in a week than in a day.
3) On all graphs, I suggest adding units of measure to the y-axis label, such as "Height of plant (cm)".
4) For the data on plant weight, are the data shown in the graph the averages for each concentration, or did you put all the plants together from one treatment and get a total weight? I think the correct way to collect and analyze these data would be this: a) measure the weight of all plants in each pot to get 2-3 measurements for each salt treatment; b) divide those weights by the number of plants in each pot to get a weight per plant, because some pots had 4 plants and some had 5; c) take the average weight for each salt treatment.
I'm going to try to upload the graph I made of your data. This may or may not work. I included only 6 of your measurement days in the graph - I think I'm missing one week of data.
Best regards,
Andrew Schnabel
Hi Team,
I noticed that your experimental design is still in draft form. Please update that today. Make sure your salt to water ratio is clear - I see .8 salt but no explanation of units of measurement and how much water you were dissolving the salt into.
Journals: Make sure you are writing about your conclusions as you discuss the results with each other. I should see updated journals posted from everyone. Luke's is missing. Post your graphs, too.
Next, go to this Planting Science resource page . Your group needs to answer these questions - in writing. Post your answers here on the blog so your mentor can give you feedback.
Keep up the good work!
Our group just discussed the article because our sub told us to. Let us know if we needed to answer the questions either way.
Thanks!
Jazzlyn
Hi Everyone,
You have been working hard with documenting your experiments, so please make sure that your most recent journal has been uploaded to your Planting Science Files tab. The file name cannot contain your last name, and it needs to be downloaded as a pdf. Please do not attach Google docs!!
Good morning Quinn and team -
Yes, I've made a line graph for the height data as well. If you can upload your graph - either a screen shot of the graph or perhaps the actual file you used to create the graph - then I'd be happy to compare mine to yours to see if we agree.
Best regards,
A. Schnabel
Hi,
We did line graphs for our height data, and I think that we are doing bar graphs for the total weight.
Dear DBTs -
Very cool photos of those roots. Did you measure them? If you did, what were the procedures you followed? If you are going to do a presentation, perhaps you could include those photos and label them with their treatment, as they show multiple differences in plant size and other features.
Best regards,
A. Schnabel
