What do we know about plants from our experiences outside of school? What have we discovered in class and background research? What questions about plants interest us?
Research Question How does water percentage effect growth of soybeans?
Predictions If the water conditions are ideal(75%-80%), the soybean growth will proceed at optimal rate. If exposed to standing water (100%+), then growth rate will be stunted. If enduring less then 25% water, growth rate will decrease.
Experimental Design Our group germinated three separate trials of three seeds in groupings of three pots each and only two trials ended up germinating. Once germinated, we proceeded to expand the time between watering to one of the groups to 25 mL every seven days. Another group we kept as control group, which we...
Conclusion In the end our flood trial had the biggest and boldest leaves as well as grew to be the tallest and had the best overall growth rate. Our drought trial slowly stopped absorbing water and towards the end started dying from the top down showing that water was no longer being transported throughout...

We were one of the winners of the star awards for planting science!! Thank you so much for helping us along the way we couldn't have done it without you!!

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. 

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. 

Please come back and visit the PlantingScience Research Gallery Archive anytime (Found under Community>Projects) to view this project in the future. You can search the Archive by key word, team name, topic, or school name.

Good bye for now. 
Warm regards,
The PlantingScience team

Hi Muskateers!

Thanks for letting me accompany you on your science journey this semester it. I am glad you had fun and learned a lot I also had a great time and would not have guessed the flooded plants would grow the best! Stay curious and keep science-ing!

Today is supposedly our last day of communication so I'd just like to express how thankful all of us in the group are for you being our mentor, you've helped us so much with conducting information and solid evidence as well as been just down right wonderful at responding in a quick and informational manner- so thank you from us to you! We'll be following you on YouTube and hope you the best!

Ideal growth rate: 2.5% each day (stoped calculations after decapitation because this stopped growth completely) 

This is also our control group and the trial that we used to base optimal growth off of.

Drought growth rate: growth slowed down until complete depletion of nutrients on 26 April, 2017.

growth rate at beginning = 2.5%

after 1 week 0-25% water = 1%

after 2 weeks 0-25% water = .5-0% 

Flood growth rate: best growth over-all! ( this portion of our hypothesis was rejected: that the standing water would stunt the growth of the plant)

Growth rate at beginning = 3% 

after 3 days w/ standing water = 3.5% 

after 1 week w/ standing water = 4% 

End growth rate = 4% 

In the end our flood trial had the biggest and boldest leaves as well as grew to be the tallest and had the best overall growth rate. Our drought trial slowly stopped absorbing water and towards the end started dying from the top down showing that water was no longer being transported throughout the entire plant and lack of nutrients in the area with lack of water died off.

It's our belief that the are paler and limper because the aren't actually rooted in the soil, their roots are floating. We believe this is effecting the amount of nutrients they are able to absorb, as for the limpness this could be because their roots aren't offering them any real support because they themselves aren't really stabilized in/ around anything

    Fantastic hypothesis! That makes a lot of sense.

Sydney
said

One of the biggest differences I have noticed is that the ideal trials soil is mainly dry on the days we have to water them (every other day) and the drought trial, which we have only watered on fridays, soil seems to almost be rationing the water if that makes sense, the soil is still damp even though we haven't watered it since Friday but the beans are still growthing just at a slower rate. The flood trial seems to have gotten even paler and gone almost limp like.

    said

    Interesting observations! Why do you think the flooded plants might be pale and limp?

Jennifer Robison
said

Oh no! I'm so sorry to hear of the decapitation! It is possible the weight of the growing seedling was too much for the stringy stem. Other than your one loss do you see/measure any differences between the groups?

Sydney
said

We have loss amoungst us. One of our thinner and tall beans in the ideal group was decapitated.... we are guessing that the effect the classroom lights have on their growth also effected the strength of the stem..

Nice photos! I see what you mean about paler for the flood. Have you been measuring length? Another aspect you can measure is how many nodes, the part of the stem the leaves attach, to see if one is growing faster or slower developmentally than the others.

Ah yes growing under classroom light makes sense why the look stringy Are there any differences between the treatments yet?

    Jasmine
    said

    The plants that are under flood conditions are looking paler then the other plants. The ideal and drought conditions have not had significant differences yet.

Your seedlings look a little long and stringy, how bright is the light they are getting? The seedlings will reach towards light so if light is low they will grow longer trying to find it.

    We aren't allowed to use are school greenhouse due to some "misbehavior" our fellow classmates chose to partake in so the are really only exposed to the classroom light

Sydney

We have officiallly started our experiments and they are growing really well so far. At what point do we need to transfer them into bigger pots? 

    Jennifer Robison
    said

    Once they have their unifoliate leaves you should be ok to transfer. If you see roots sticking out of the bottom of the pot you can damage them by moving them to new soil.

Can't wait to see them grow! Thanks for sharing photos I greatly enjoy seeing them Also good catch and fix for your off-set planting!
