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 Tuesday, November 24, 2020, 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

Analisis: 

Over the few weeks that my wisteria seeds were in the bag they did not grow. On the other hand my cucumber seeds that have been in their own bags for just over a week  are doing pretty well. The seeds that were closer to the light inside Grew more. 

 

Conclusion: 

    My wisteria tree seeds were in their own bags for just over three weeks, or just under three weeks somewhere close to three weeks. It did not show any growth and did not show any sign of germination. My cucumber seeds are just over there for the first week, so a week and a half of data and they have sprouted well.

    said

    Great, I'm glad that you got the cucumber seeds going so that you could see some germination and compare. Do you have any ideas about why some seeds would take longer to germinate than others? Can you think of a reason why a crop plant (cucumber) would germinate faster than the non-crop plant (Wisteria)?

Zivko Jovanovic
said

Dear team,

I hope you are doing well.

As you can see,some seeds germinate faster than others...and you also noticed that there was difference depending on the light source...

Keep doing...

Nick
said

as of today, my cucumber seeds are starting to sprout, and I have noticed that the ones that are closer to the light are doing better than the natural light 

Nick
said

for the floating disk lab, I had a question, Does the distance from the light matter for the floating disk lab?

    Nora Gavin-Smyth
    said

    Yes it should make a difference. You just want to make sure that when you are comparing between two treatments that the light is the same for both. You might get more clear results the closer your light is.

Rayna
said

we did a floating disk experiment and this is the data we collected: 

http://www.w3.org/1999/xhtml">
Time baking soda water + drop of soap- CONTROL
0 floating a litttle @ bottom no float
5 floating a litttle @ bottom no float
10 hovering at the bottom some floating
15 2 came up to the top more floating to the top (6 or 7)
20 6 floated to the top more floating at the top then at the bottom
25 9 at the top, 5 completely at the top 6 floating- (one floated down) they arent fully at the top, hovering at the top
    Nora Gavin-Smyth
    said

    That's so cool! How many floating disks did you use total for each treatment? Could you explain why the baking soda treatment would have different results?

Rayna

It is now day six and my seeds that are under the natural light have yet to grow. I am unsure if I am over water them or they just need to breath for 10 minutes or so without the damp paper towel. The seeds under the lamp are doing good, they are sprouting more and absorb all the water I dampen them with.

    Nora Gavin-Smyth
    said

    Ah, I see, so it's the seeds under the artificial light that were developing faster, but now that has slowed down since they have begun sprouting. Can you think of a possible explanation for this?

Rayna
said

For my seed lab I am using lemon seeds. I live on the east cost area so right it is changing seasons. We are having a lot of gloomy days. I started my experiment 5 days ago and the seeds that are under the artifical light have absorbed the water much quicker and seem to be sprouting. The seeds under the natural light are barely even absorbing the water.

    Nora Gavin-Smyth
    said

    A lemon tree would be a fun plant to continue growing even after the experiment! That's good that you're already seeing some development in the seeds under natural light. Do you think that the natural light and the artificial light seeds are experiencing the same temperature?

Rayna
said

When was the first experience that influenced you to know this is exactly what I want to do, be in the science field.

    Nora Gavin-Smyth
    said

    Thanks for the question Rayna, for me it was when I was an Americorps volunteer working on natural areas restoration. I was removing invasive species and planting native species and I loved being outside and learning about plants, knowing their names, their ecology, and the interesting things about their biology. I wanted to do this as a career because it was something I was passionate about, I could do it well, and the world needs people working on helping plants and natural areas. I wanted to be a scientist because I wanted to work on the unanswered questions in the field, and be one of the people who helps move the field forwards.

Hey, so my seed looks pretty mcuh the seed looked like yesterday, I have noticed that just in one day the root has actually grown alot longer. I also noticed that the there is a new stem growing from the pod under the lamp, just so you know the original stem have grown and left the that pod but now, there is a new one forming.

Nick
said

hey, so I have discussed it with Miss Cost, about my seed lab and I will be continuing the current seed lab and I will plant cucumber seeds. other than that my seed lab is going great I have seen minimal to no growth, is there a way for me to help seed up the lab other than heat? 

    Nick
    said

    my seed is showing no growth but I have used the cucumbers seeds as well as the wisteria seeds. 

    Nora Gavin-Smyth
    said

    Good to hear that you are trying a different kind of seed. From gardening, I know that it is a good idea to make sure that your cucumber seeds stay above 70 degrees F in order for them to germinate quickly. Other than that, just make sure that they stay moist! It'll probably take a week or more to germinate. 

Amber

 my seed in natrual sunlight is doing pretty well I would say, because  the pod that has a black stem is already starting to grow roots. I was really unsure at first when the black stem appeared I thought that this seed was not going to grow, but after observing it for 3 days, everyday I could see little roots starting to grow from the bottom of the pod/the end of the black stem which I thought was mold, honestly. The second seed placed in natrual light is just starting to grow ans begining to sprout in a week, I think it's because I didn't place it in the direct beam of sunlight. Or the fact that this particular seed was covered completly by the wet paper towel, whereas the other seed was covered partically. My seeds in the artifical light, as you can see the stem and the roots have completely seperated from the seed and it is growing on it's own with a leaf growing on top of the stem. Whereas, the other seed is just begining ot sprout but I think the problem here is the same as the seed placed in the natrual light. That this particular seed was covered completly by the wet paper towel, whereas the other seed was covered partically.

    Nora Gavin-Smyth
    said

    Sounds like you have some good ideas about why the seeds are growing at different rates. Do you think that it would be the same if the seeds were covered in soil / half covered in soil?

Amber

I have a question too, What made you guys want to be a scientist, and why? What areas are you guys studying right now or researching/making a project right now? I'm always curious about this!

    Zivko Jovanovic

    Hi Amber,

    Regarding your question-I have started just like you, with biology section in Elementary School, and I was "infected" by biology, especially plants. I studied molecular biology, finished my PhD in plant mol.biology and now I am working as a senior research associate at the Faculty of Biology. I investigate the interaction of plants with benefical bacteria isolated from rhizosphere (around the roots) of another plants. So, something like probiotic for plants. Those bacteria may help plants to grow (better) under normal and stress conditions.

    Hi Amber! That's a fun question to answer... I became a scientist a little later in my career. I became really interested in plants through natural areas restoration--I did this as an Americorps volunteer after college, removing invasive species and planting native species. I really loved being outside and learning about plants, knowing their names, their ecology, and the interesting things about their biology. I wanted to do this as a career because it was something I was passionate about, I was good at it, and the world needs people working on helping plants and natural areas. The big thing I needed to do to achieve this was getting research skills. That's why I went to graduate school and got a Master's degree. While I was doing the Master's degree, I got even more curious about bigger picture questions in plant biology like how we came to have such a diversity of plants across the world and why some parts of the world have more diversity than others. That's why I started my PhD, which is what I'm doing right now. I study a group of plants that has become very diverse in East Africa (Tanzania), and I sequence the DNA of these plants to figure out how the species are all related, sort of like making a family tree that shows how and when new species were born. I also use their DNA to figure out how healthy their populations are today so conservation can protect them better. I do a lot of field work collecting plant specimens in Tanzania, then I extract their DNA and sequence it back in the lab here in Chicago.

Hey so one of my lab mates result was around the same as mines, Nicks and Rayna. That the seed placed in the sunlight grew faster 2-3 days faster then the one in the artifical light.

Rayna
said

day 12; both seed samples have sprouted. the lamp seeds more than the natural light seeds, but both have sprouted. the seeds under the lamp grew at a much quicker rate than the natural light seeds. the amount of water differed due to human error, so that could have effected the natural light seeds growth rate. giving the natural light seeds a few minutes to come in contact with oxygen proved to help the growth of them.

Rayna
said

now day 11 and the seeds are both (seeds under the lamp and under the natural light) growing, I water them daily and make sure there is not vent or fan near them. The seeds under the natural light seem to benefit much more when I water them after I let them breathe (or come in contact with oxygen). The seeds under the natural light have began the sprout.

Rayna
said

seeds are the same on day 10. The seeds under the natural light are showing some sprouting but not much. I am letting the seed breathe for 3 minutes each time before I water them. The seeds under the lamp are not growing as fast as they used to but still growing. 

Rayna
said

It is day seven now and the seeds under the natural light are doing better. I let them breathe for 8 minutes without the towel so they could dry up a little and it seems as that helped. The seeds under the lamp have not grown in a day not sure if I put too much water yesterday by accident.

Amber
said

My plant looks the same this weekend, I checked it everyday. However, I am noticing that my seed growing in natrual sunlight looks more like an actual plant, the roots are much longer and the stem is much thicker and overall it is just doing better. Whereas, my seed in artifical light looks smaller and more fragile. What I mean is that the seed's roots are so tiny compared to the one in natrual sunlight, the stem is so much thinner and it is not growing that much. Like my seed in natrual light the black stem is fading away and there is a big leave growing from the pod.

Hey for my seed lab I am using wisteria tree seeds, I am in the New England area, and I started my experiment on Sunday of this week. I can see slight condensation while my seed is fully covered with a damp paper towel. Other than that there is no major change in the seed itself.

    Nora Gavin-Smyth
    said

    You will have to be patient with those seeds! With their tough outer hulls, Wisteria seeds can take about a month to sprout. Can you think of anything you could do to the seeds to speed up germination?

    Nick
    said

    I can keep the seeds warm as well as get some seeds that will grow faster if that is what you would prefer. I am still recording data for the seed. 

    Nora Gavin-Smyth
    said

    I'd like to get your teacher's input on whether you should get another kind of seeds, and Zivko's. My thought is that it would be better to find another kind of seed to plant so that you can get results before the end of this unit. However, I would continue to germinate your Wisteria seeds and measure them, and you could compare them to another kind of seed.

    sounds good

Hey,so it has been 10 days since I first planted my seeds, I am noticing that all of my seeds are growing really well even that one seed that the stem is black, it actually have grown alot from Monday. I'm notcing that my seed in the artifical light is growing so much better then my seed in natrual sunlight, because the ones under the lamp is actually starting to grow leafs where as the one from the sunlight is still sprouting. It's actually really weird to oberve how soybeans is growing because the stem of all of my beans are sprouting in the weridest shape possible, Like there is one that sprouted from the end of the seed but then it started to grow in the middle (this was placed under the lamp), I have another one (Placed in sunlight) that is already growing a tiny little new stem from the orginal stem it sprouted from!
