Info

Explore In the photosynthesis process the reactants are carbon dioxide and water. The products are oxygen and glucose. In cellular respiration the reactants are glucose and oxygen and the products are glucose and carbon dioxide. If the seeds are fresh then seeds can grow as little as 1 day.
Research Question Does the type of seed affect how fast the seed germinates?
Predictions If the type of seed is "corn" then it will grow quicker.
Experimental Design We will be using the bottle's edge method. We will be using 7 different types of seeds per person. We will also be using water, soil,bottom of a plastic drink container, paper towel, and the light from the room. We will be changing the type of seed and we will be keeping the time that is...
Conclusion What claim can we make from our experiment? What are possible explanations for our results? How do the data we collected and our reasoning with scientific ideas support our claim? What future experiments could be done to expand on the results of this experiment?
About this Project

This team did a great job of planning their project and communicating with their mentor. When they were planning their project, they realized that their original research question could not be done properly and so they pivoted to a new research question. They also communicated their results...

Updates

Get to know your team’s scientist mentor, who will encourage and guide you through the scientific process of discovery. The more you share your ideas and research info, the more your mentor can help. You may also hear from a scientist mentor liaison who will be helping all the teams in your class.

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.

Here is my explanation.  If you use corn then it will germinate the fastest.  Many plants were close with two days but corn germinated in one!  The day after planting the corn it had already germinated.  This happened because the corn grows best in warmer temperatures.  If we kept the corn growing then it would have reached 37 inches.  Corn grows very slow in 50degrees or lower.  The other plants did not grow as fast because they cannot grow as fast in cold temp.

    Hi Taryn,

    Thanks for the update. So your hypothesis was that corn would germinate the fastest, and it did. And you think it is because it grows well at room temperature? Do the other species not grow well at room temperature?

    I would also encourage your team to consider the effects of different species. Different species have different DNA and different genes that tell them when to start to grow. You might also want to tie that in to your explanation. 

    Good work!

Taryn

Yes our prediction was correct. We thought the corn would germinate first and it did.

Hi Teams and Mentors! First thank you so much for helping us out in this project. Today students began to update you with their explanations/conclusions for their investigations. Tomorrow, we begin spring break. My intention was originally that we would be done at this point, however, we are going to be wrapping-up after break. Please feel free to add any feedback on their conclusions, and they will view it when they return.

Thank you again!

Why do different seeds germinate at different rates?

    Hi Maddie,

    Thanks for the update. That's a pretty sweet looking graph! It's a little hard for  me to read it, but I think it says corn germinated first and then some other species germinated last. I can't tell exactly which species are written along the bottom, sorry. Very nice! Is that result in line with what you expected to happen? Is your hypothesis supported? 

Taryn
said

Yes! We have measured the plants today which is the last day.   Our prediction was actually correct, the corn germinated the fastest.  The corn was also 7 inches!

After coming back from the weekend, we found our plants have grown a lot over the past 3 days and they have actually started to become real plants and have started to grow leafs.

    Hi Maddie,

    That is so exciting! Isn't it amazing what little seeds can do? :) 

    Are you taking measurements or making comparisons between your treatments yet? 

    Keep me posted!

Taryn
said

So all of our seed have germinated and some have even started to grow as well. 

    Angela Jean McDonnell
    said

    Hi Taryn,

    All of  your seeds have germinated! wow! That's pretty neat. Did they all germinate at once? Do you see any differences among your treatments? 

    What kinds of things are you recording and measuring?

    Maddie B
    said

    We are measuring the rate of how fast they have germinated. Which they are all coming at different rates and some are not moving past its roots but some have started to grow and become quite large

We just sent some pictures to you of the germination process. We also used buckwheat, soybeans, peas, ryegrass, fabacae, alfalfa, and poacae.

We had a little malfunction on our pictures. The seeds did not end up showing up on the photos (obviously).  We will send them again,  thank you.

 We actually have just updated our question.  We realized that the freshness is not a 100% sure process to figure out.  So, we changed it to, "Does the type of seed affect how fast a seed germinates?"  We were also wondering, how do we know when a seed is germinating?

    Angela Jean McDonnell
    said

    Hi Maddie,

    No problem changing your question; I think that's very fair given that you don't know the age or conditions of the seeds you have.

    So you'll be testing different seeds and their germination rates? I think that sounds very reasonable and like a great idea, too. What seed types will you be using? How will your group treat the seeds?

    Keep me posted!
