Info
| Explore | Without previous knowledge of plants outside of school we know that plants need sunlight and water to grow. They have roots that help ground the plant, we also know they reproduce by producing flowers and spreading pollen. In school we learned that all plants go through photosynthesis and that... |

| Research Question | Does the amount of fertilizer effect the phenotype of the plants being grown (plant height, leaf size, color of the stem and leaf, and trichomes) |
| Predictions | Plants with more fertilizer would have greater growth, have darker leaves, and produce more seed pods. |
| Experimental Design | We followed all the guide lines for planting the seeds given to us through the planting science site and only altered the amount of fertilizer between two groups. We gave one group four times the amount of fertilizer as what was considered normal, the other group received the normal amount ( 6... |
| Conclusion | We can accept our hypothesis because there was a color change within the leaves and saw the same amount of growth within all plants. Plants with less fertilizer had more yellow leaves and the ones with more fertilizer had more green leaves. |

Updates
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. 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
Just as a reminder, the end of this session will be 11/29/2019. It’s great to see that teams from your school are wrapping up. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
Those are great choices! Do you have any predictions about what the offspring will look like?
Today we decided on the plants we were going to cross pollinate, we are doing Purple/ Green with Green/ yellow and really hairy with hairless. when we got to school after the weekend a good bit of our flowers had actually pollinated themselves, so we had to choose ones that had not been pollinated.
Hi all! I hope that your test went well :)
Also, I'm glad to hear that the plants have flowered! That's great news!
I'm not sure exactly what you want to know more about regarding the pollination. Are you making "bee sticks" to pollinate with? That method works really well. Let me know if you want more information about how to do that. Or, were you asking about which plants to cross pollinate? If that was more of your question, I like the idea of crossing two plants with very different traits. If you do that, what traits would you expect the resulting offspring to have?
A lot of our plants have flowered. we had a test today, but we are going to measure out trichomes tomorrow. we are about to cross pollinate them and we have to figure out what traits to pollinate for. we can try and get a plant that is purple with yellow leaves or even a green plant with green leaves. We would love to hear your imput on how we should pollinate them.
Hi team,
Great to see those buds! You should have flowers very soon!
I was just wondering if you noticed any traits that are more different across the individual plants. For example, maybe all of the plants have approximately the same number of leaves, but some plants have purple stems while others have green stems. In that case, I would say that stem color is particularly (more) variable relative to leaf number.
I believe that the plants you are growing are expected to have some traits that are variable because the parents used to generate the seeds had different traits. Do you know what any of those traits are? And, do you see that pattern in the plants?
Please let me know if my questions are confusing, or if you have any other questions.
Cheers,
Kate
what do you mean when you say particular traits and what are some we should look out for. Thank You

none of our plants have flowered yet
Oh - that's great! Your plants look really healthy! I'm excited to see what the flowers look like. Have you noticed any particularly variable traits in the population so far?
Hi! It sounds like things are going very well! That's awesome!
Using the sticks to support the stems was a very good idea. It's really common for plants that are grown indoors to need a little extra support (in at least some plants, stems don't produce extra supportive tissue unless they experience wind and usually there isn't too much wind indoors!).
Also, did you add the fertilizer to all the seedlings or only to some of them?
I'd love to see photos next time if you have the chance to take some!
Best,
Kate
Hi! Today we got our plants and made more observations, we measured the stem height and the width and length of our true leaves. We did do a nutrient treatment by adding extra fertilizers. I'm so excited to see them grow even more! We even used thin wooden sticks to help support the stems from falling over and also support the ones that have already fallen. We noticed that our flower buds are showing up so we should soon be seeing some flowers! Maybe next time we get to observe them we can send you pictures.
It's great that your seedling are growing and that true leaves are starting to come in!
Are you guys doing a nutrient treatment or simply looking at the F2s in one environment?
Today we measured our leaves and stems, created tables. some of our stems fell over, maybe because they were too heavy. we believe the color will stay the same, and we observed that some of the leaves have changed colors. We noticed that our true leaves came in
Hi! That is great! It sounds like things are going well and that you have a good plan for measuring traits going forward. What are you expecting to see happen with the plant color/anthocyanins? Keep up the good work!
hello we looked at our plants today(day 3 after planting) and our tallest plant stem was 2.5cm, and in 3 of our 8 cups all 6 seeds germinated.
We made a table and we are going to look at the following characteristics
.stem height(cm), first leaf length/width (cm)
and we are doing color using a scale on 0-4 where 0 is green stem and 4 is a dark purple and the darkness increases as you go from 1 to 4, so we can measure Anthocyanin
Hi team,
I'm glad to hear that the plants germinated!
Usually, the traits that you choose to measure are somewhat determined by your research question. For example, if you want to know how the amount of sunlight affects plant growth you would measure general size traits (e.g. plant height, stem thickness, or the number of leaves). Alternatively, if you want to know something about how salt concentration affects plant root health you would measure root characteristics (e.g., root length or the number of "root hairs", which are smaller projections that come off the roots). So, do you have any research questions in mind that might help guide this choice?
That said, the traits that you suggested are both good! The rate in which the plant grows is often an interesting thing to measure no matter what research questions you choose, and color is something that is studied less often, which makes it interesting in a different way! If you choose to measure one or both of these things, think a bit more about how you would actually measure them (e.g. Will you measure color using descriptive categories like "green", "green-yellow", "yellow", "brown" etc ? or How will you measure size to determine growth rate? Would it be useful to measure plant height or the number of leaves?).
I hope this gives you some more ideas, and please let me know if you have any more questions.
Keep up the great work! I'm looking forward to hearing more,
Kate
Today our plants germinated, but we are still determining what we are going to measure. We have some ideas in mind like the color and the rate in which the plants grow, but we would love to hear your input on ideas of what to measure.
Hey my name is Zander, I go to Lincolnton High School and am in AP Biology. I enjoy to cook and do sports, I play 3 sports at LHS such as Varsity Soccer, Swimming and Tennis. My strong suites are math and science and I always want to have fun.
Hi Team! It's so nice to meet you all!
My name is Kate, and I'm a biologist that works on questions about how new plant species are formed. In my free time, I like swimming and reading.
I'm glad to hear that you have started your investigation. Do you already have a question in mind for your project? What do you want to know about how plants make a life?
I'm really excited to work on this project with you!
Cheers,
Kate
Welcome to your PlantingScience project page!
Welcome to this community of plant researchers. As your team plans and conducts your own research project, you will be mentored by a scientist. The mentor's role is to encourage and guide you through the process of scientific discovery. The more you share your ideas and research information online, the more your mentor can help.
