Info
| Explore | We know that the seed needs water, soil, and a good environment to grow. Will peeling half of the seed coat affect the growth of the seed more or less than peeling the whole seed coat. When we conduct this experiment I would like to learn the affect the seed coat has on the seed. |
|---|---|
| Research Question | How does the absence of the seed coat affect germination rate? |
| Predictions | If we peel the seed coat than the seed will grow faster than the seed with the coat because the seed won’t have to push through the seed coat when it is germinating and the seed will be exposed to the water more. |
| Experimental Design | Step 1. Fold a piece of paper towel and put it at the bottom of the Petri dish Step 2. Put five seeds in each Petri dish and space them out evenly (six Petri dishes) Step 3. Water the seeds with five milliliters of water Step 4. Repeat step three every other morning |
| Conclusion | Peeling the seed helps speed up germination. The peeled seeds started with 3 germinated seeds and ended with 9 seeds. In the week that we conducted this experiment, there were 6 seeds without the seed coat that germinated. The seed that had the seed coat started with 2 seeds and ended with 3... |

This team came up with a creative investigation question that tested their prior knowledge, and showed persistence and curiosity as they figured out how to test their question. They communicated well with their mentor, especially when working to design their investigation. They showed great... |
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
It’s great to see that teams from your school are wrapping up and posting conclusions. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
Hey All,
It was wonderful working with all of you. I really liked the way you worked and especially enjoyed your graph. I like how you chose to make a bar graph rather than a line graph, since the bar graph is more accurate as you have data for discrete days. In short, I really enjoyed working with your group.
Good luck!
Thank You for helping us with our planting science envistigation.
Thank you Sonal, for helping us with our project and teaching us more about plants and what the seed coat does for the plant. Thank you so much. I had fun with this project, I hope we do something like this again soon.
Okay, thank you. We will definitely talk about that.
This looks beautiful!
But another thing to think about would be why do half-peeled seeds do worse than not peeled seeds for the first two days.
This looks awesome!
Do your predictions align with what you are observing?
Our seeds are doing GREAT!! We already have a few seeds starting to germinate. They look amazing.
When we checked up on our seeds today, we watered them because they looked a little dry. Over all they are doing great.
We will definitely be careful when we use the clippers. We changed the prediction so that it included how the water will affect the seed without the coat. We were also thinking about having ten seeds where the seed has the whole coat, ten seeds where half of the coat is peeled, and ten seeds when the whole coat is peeled.
Great!
Just a minor suggestion: I think rewording the research question would be a good idea. Maybe something like "How does the absence of seed coat affect germination rate?". But this is just a suggestion.
I am also attaching a basic seed coat-germination presentation that might help the team gain some more insights into the role of seed coat. You dont need to into the details of the presentation, but I thought just going through it would help.

We are working with Nasturtium seeds. We just tried pealing the seed and we got some off. Also, we looked online and found that we could use some nail clippers or sand paper to get the seed coat off. We expect that peeled seed will grow faster because the coat is not on the seed so it wont have to push through the coat. Yes, we are planning on comparing how long each seed takes to grow/which seed will grow faster.
Using nail clippers is an excellent idea! Just be careful to not damage the seed.
I like the reasoning and the predictions, but also think about what the absence of sead coat does to the accessibility of water.
Oh nice! What seeds are you planning on working with?
I like your question about what effects will peeling a seed have on the germination rate. It is possible to 'peel' some seed, but this has to be done very carefully so as to not damage the seed. Basically, seeds have something called a seed coat (to protect the seeds), which can technically be removed. I would suggest that instead of peeling the store seed, peel only a part of it. Also, how are you planning to do this?
What do you expect will happen if you peel the seeds? Are you planning on having a control (an intact seed)?
We are hoping to learn about what different things will effect seed growth. We will not be working with sunflowers, we just like them. In class today we were coming up with questions for our investigation. Our favorite one is, How will peeling the seed affect how fast the seed grows? We were wondering if it is possible to peels the seed.
So great to know all of your interests. I am a plant biologist, so I love plants and have a lot of them at home. I work with sweetpotatoes, yum!
For the project, I am assuming we will be working with sunflowers? Also, what are we hoping to learn from the project?
Looking forward to hearing more!
Hi, I´m Sami. I like volleyball, drawing and reading. I have a dog and a cat. There are 6 people in my family, my mom and dad, my sister, and my brothers. My favorite subject is ELA. I also like social studies.
Hi, my name is Mia. I love to dance and have been doing it for a long time. I have 3 cats and love most animals. I look forward to working with you as we learn about seeds.
Hi, my name is Mia. I love reading and playing with my twin sister in my free time. I have always loved plants and science so I think that I will like this project. I'm looking forward to working with you!
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. You can also find out more about your mentor. What is their research about? Why did they go into science? What do they like to do when they are not working?
You may also hear from this classroom’s assigned scientist liaison. Liaisons work with several mentors and help make sure the conversations are going strong. They may also offer some extra advice or encouragement.
Two resources can help you get started:
Best wishes as you start this scientific journey. We are all pleased to share this experience with you. Have fun!
