| Research Question | Would the buckwheat plants still germinate if they aren't subject to sunlight? |
| Predictions | I don't think they will grow-Kayden I don't think they will grow-Lizzy |
| Experimental Design | Our plan is to plant the Buck wheat in plastic bags with a wet paper towel.Our control group will be in the full light while the other groups are locked in a cupboard.Our materials are plastic bags,Paper towel,Water,Cupboards,Sunlight/another light. |
| Conclusion | Did the Buckwheat and Alfalfa grow?Yes it did!So in conclusion our hypothesis were wrong the plants did grow.The sunlight ones show a 4 inch(10.16 cm) difference from day 1 and the sunless ones show a 3.2 inch (1.128 cm)difference from day 1!That's the buckwheat,we ended up doing some Alfalfa... |

thinks stephanie for being out mentor have the time and answering our question and making us know what to do for our project hope to see you again
You're welcome! Hope to chat about science again someday!
Thank you Stephanie for being our mentor while Evan was away.Thank you Evan for being our mentor and helping us along the way.Thanks to both of you for asking questions to challenge us and help us along the way.
My pleasure! Good luck with your science in the future!!
Great job guys! Thank you to Stephanie for helping you guys before I was able to start commenting. I am sorry for being late, but I hope that my comments were helpful. You guys did a really good job asking questions, making observations, and collecting data. These are all great qualities for a scientist to have. I hope that you can continue to learn about plant, seeds, and photosynthesis. Good luck!
thank you for being our mentor Evan
You are welcome! Sorry I was late to the party.
Hi Evan when i mean that i plants grow in means that the roots go to the other plants roots and they combine and they grow together and its awesome because what in seed because how they grow from sunlight and water because its weird because plants have many ways to grow but why cant there be one and how does the plants get energy from the water or the sun
Wow Kayden that is really interesting! The seed usually has all of the necessary materials to jump start the growing process. There is enough energy, or stored carbohydrates, in the seed to help it grow to find water and sunlight. Once the seed can start taking up water, carbon dioxide, and sunlight a really fascinating process called photosynthesis can occur. Photosynthesis is basically how plants take carbon in the form of carbon dioxide out of the air and turn it into carbon in the form of structural and nonstructural carbohydrates.Plants also need nutrients from the soil to help them grow big and strong. I think that this processing is so fascinating, and there is a lot to learn about it if you want to look into it on your own.
If we expose our plants to the sunlight would that affect things drastically?Should we try and keep them in the shade or do we quickly bring them out measure them and then get them back into pitch black asap?
Hi Lizzy-see my other comment, but for your experiment I think working quickly to minimize the amount of light the plants from the dark treatment receive will be best.
Today the plants without sun are 3 inches and the ones with sun are 3.5 inches!Our plants are making progress but I still think that there is one flaw with this,when we measure the plants we have to bring them out into the sun.Do you think this could be an issue that would affect the experiment greatly?
Hi Lizzy-you identified what may be a "confounding factor" in your experimental design. If you wanted to be extremely serious about keeping the plants in total darkness, you could use a red light to illuminate them while taking your measurement. That way you could still see them, but they wouldn't be getting less of the light spectrum.
thanks
Hi Evan thanks for being our mentor it was great having you to answer our questions and to tell us what is in plants that make them grow thank you
I just uploaded some pictures,enjoy!!
hi Evan our plant don't have any sparks because some of our plants have died and some joined together but we gave both of our plants water the one with out sunlight and the one with sunlight but the on with out sunlight the alfalfa seed died but the buck Weat is still barley hanging on but were still trying our best to make our plant stay alive answer this question please how do the plants grow into each other and how do they make seeds grow flowers like what is in the seeds i really want to know
Hi Kayden-you have a lot of really good questions! I'm not exactly sure what you mean when you say the plants grow into each other. Are you talking about the ones in your experiment? What do you think might be in the seeds that help them grow? Is that something you can talk about an explore with your group members and let me know what your thoughts are?
The plants without sun are 2.8 inches tall!The ones with sun are 3.0 inches tall!These plants show a .4 growth for the ones without sun and a .0 growth for the ones with sun.The measurements I compaired these with are the oldest ones that I recored besides when they didin't grow at all!
Great job recording your observations! This is an important part of the scientific process. Having notes and data to look back at can be really helpful as you are trying to understand why your experiment happened the way that it did.
i never knew roots have hair but some of our plant grew all together and some of the alfalfas plants died like some of the roots just fell out of the seed.
Hi Kayden-the roots have hair, but they provide a different function than our own hair. The plant's root hairs help to absorb water and nutrients.
5 plants were planted in each bag.5 with sun,5 without sunlight. That's not how many grew though.5 plants grew with the sun and only 4 grew in the bag without sun. The plant grew into the paper towel because the roots needed something to dig into besides soil.
Hi Lizzy-this is a great idea as to why the plant grew into the paper towel.
Great results guys!! Keep on measuring and recording!
hi stephanie we grew 5 buckweat and 5 alfalfa in the shade and 5 buckweat and 5 alfalfa in the sunlight but the ones in the shade are barley hanging on but were trying our best to keep them alive
both our plant grew but one grew in the paper towel how did it do that and what is the fuzz on the seeds that are on the growin g part
How many plants did you have in sunlight and out of them how many grew? How many plants did you have in shade and how many grew?
Without seeing it, I think the fuzz is probably fungus!! In my lab we often get fungus when we sow seeds. It shouldn't affect the seeds too much if it doesn't get out of control.
When you say that one grew in paper towel, and why did it do that, was it one that didn't have sunlight?
Hi Kayden! It sounds like you got to see the incredible power that is stored inside of each seed! Just think that even the biggest trees start out as little seeds. When a seed germinates, or begins to grow, it is kind of like a tiny explosion that keeps on going!
Like a firework, the seed needs some kind of 'spark' to get it going. For seeds, the 'spark' is usually light, water, temperature, or a combination of each of these factors. These are important 'cues' for telling the seed when to germinate, so that the 'explosion' can be fueled.
What kind of 'spark' did you give to your seeds? It sounds like you gave them water, and some got light and others didn't. These are your 'treatments', or conditions that are applied in a controlled way to test your hypothesis or experimental question. How do you think your treatments affected the ability of the seeds to germinate?
If someone were to come up to you and ask how to germinate buckwheat seeds, what might you recommend? This is an example of a practical application of your experiment, or how your experiment can benefit someone in real life. For me, this is the most exciting part of doing scientific research!
p.s. the 'fuzz' on the seeds might be root hairs. try googling root hairs to learn more!
but what if they don't grow do you have any ideas for another way
Do you think maybe you could try partial light?
We have ended up using the lights from our classroom and locked the plants that don't get light in the cupboard.
Ok great! Did you take some pictures of your set up? I would love to see them!
Ok so that sounds like an interesting project idea. Are you going to put it in direct sunlight? Or use a different type of light source? What's your hypothesis for your experiment?
the idea we have is to put the seeds in plastic baggies with some water and paper towel and put one in a drawer and block out the sunlight and let the other stay in the sunlight
Also, do you think for sunlight you could test more than simply full sun and no sun? How about shade?
Can Buckwheat grow without soil?Its snowy here and we cant get any!
Do you not have access to soil for the project? Can you guys make a list of all the equipment you have available and post it into "Info"? That would help with choosing what sort of questions you are able to ask.
Did you guys change your name again? I couldn't find you on my list!
My guess of what will happen is the Buckwheat wont grow at all because it doesn't have enough nutrients to grow.
What about the nutrients in the soil? Do you think seeds need sunlight to germinate?
Nice work... great discussion... making good progress!
As you make decisions and finalize portions of your project, don't forget to write them up in the Info Tab section... the link is found on the left under the Updates Tab!

Think of the ‘Updates’ page of your project as your ‘blog’ or ‘chat’ area to communicate with your mentor but NOT as a place to post random, silly, or personal messages. Its a group conversation and needs to be treated like a ‘whole class’ conversation… no ‘side conversations’ and stay focused on your task! Solving problems and finding answers can be hard but rewarding work and it will require your full attention!
Its time to roll up your sleeves and get your hands dirty! :)
We have decided to do the sunlight experiment.We need one control group which would be the plants growing with a normal amount of sunlight.The test groups would have a cup or cooking pots over top of them proventing them from getting sunlight.We would have to make sure to water the plants equally and have the same amount of soil in the cups/pots.We would need to do two or three tests to make sure we don't make a mistake when we do it.
Sunlight is important to plants because it helps them to create nutrients and food for themselves.We will be growing Buckwheat.
And about your possible questions for the project, I have some questions about your questions!! If you changed the pots/soil would you be changing any of the variables? I think bugs are an interesting question but what bug would you use and what would be the variable you want to test? And as for sunlight, what do you think plants needs sun for? And what about a seed?
i think the plants need the sunlight because the plants use the energy to make food for them selves
My favourite thing to do is to hang out with friends and my favorite subject when I was at school was Biology.
Hello Fire Breathing Rubber Duckies!! My name is Stephanie and I am going to fill in for a bit until your mentor Evan comes online! I am a plant biologist working on flowers and flower genetics and I work at the University of Washington in Seattle. I am actually from Australia and went to college at The University of Melbourne. I did my PhD there and then moved the US for work! I love nature (esp plants) and making pottery and dogs.
We have 3 questions we are considering.What would happen if we moved the plant/soil from one pot to another?What would different kinds of bugs do to the Plant?Would the plants die if they didn't get sunlight but got everything else it needed?
I don't think we have decided on a specific project yet!
were did u graduate at.
