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...

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. 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

Looks like you are in the final stages of your projects.
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 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.

    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.
