Explore | Plants need water, soil, and sunlight to grow. Mrs. Martin came into our class from UNH to talk about agronomy. She told us that this could be another year without peaches because of to many growing degree days. She also told us about grafting plants. Were interested in learning if we put two... |

Research Question | Would two seeds in the same spot, radish and corn, radish and mung bean, and mung bean and corn, grow better then one seed on its own? |
Predictions | We predict that the plant with one seed will grow faster than the plant with two seeds. We think this because the plant with two seeds may be affected if the two plants are trying to grow together to form into one plant. We think that the radish and corn and the radish and mung bean will compete... |
Experimental Design | Materials: -6 containers, 9 radish, 9 mung bean, 9 corn, soil, water Spacing: corn: 4 inches apart, radish: 2 inches apart, mung mean: 3 inches apart Depth: all: 1 inch deep Soil: about 6 cm. Water: 20 ml. per seed There will be six pots and three seeds in each one. First get 3 bottles... |
Conclusion | After digging up the roots to see if our experiment worked, we noticed that the roots did not grow together. A possible explanation for our results is that the roots of the plants competed for resources such as space and water.The data that we collected shows which plants grew best assuming that... |

Updates
Hi Team,
As we are finishing up, please make sure that each team member has updated and uploaded their journal, and that you have posted a short summary of your conclusion and how it relates to agronomy, and then upload your final presentation (ppt) - you should be completely done by Tuesday. Make sure you thank your mentor, too!
Hi Team,
You might not log back in at this point, but I wanted to ask you a follow-up question for your conclusions. You originally started this project in hopes of getting to plants to grow together and become one. That did not happen, but what did you learn from this that might still be useful to a farmer or someone with a garden?

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
One more item. I went through your graphs. If it were me I wouldn't use the graph with numbers written all over it, the numbers of the axes are fine. Also, your y-axis is labelled, but you haven't indicated your unit of measure. You want someone to look at your graph and be able to tell if you measured your plants in inches, centimeters, millimeters, or whatever unit you used. In science we often put that in parentheses. Example: Plant height (cm)
Hi Magnificent Melons,
This is your liaison Kayla. Your mentor, Jamie, has had to take a leave of absence, so I will help you out while you finish up your experiment.
It looks like you are working very hard on your project! I still need to look through all of your data, but one item I want to caution you is regarding your re-planted seeds. I saw a few weeks ago you averaged the shorter seedlings into the treatment data. My question for you, if the data is averaged and your re-planted plants cause the average to decrease, do you think that average would be a good representative of the actual treatment or not?
Also, how are you coming along with your conclusions?
Keep up the great work!
Kayla
Hello! Today we had growth in most plants but in the experimental radish and corn plants the average height decreased because we averaged in the new growing plants. The control corn plants have not yet grown since we replanted them.
Hi! We only have one number because we averaged the plants height. We will try and communicate more on our journals. Thank you!
Hey Team!
Glad to see more plants growing! Two VERY important things:
1. Communicate with each other...you still have different information in your journals, so some of you need to make corrections about the amount of water added to the containers.
2. For the combination plantings, how are you telling the height of the mungbean or corn; corn or radish; and mungbean or radish individually? I just see one number in this column...so how will you compare this to your control, if you don't know what plant this number refers to?
The growing plants look good! Adding soil can't hurt, unless it covered seeds that haven't germinated yet. BUT, you replanted those that haven't emerged yet so all should be ok. Make sure you've thoroughly wet the soil to encourage germination of the seeds, and that the amount added to each container is the same. What is the height of your soil now? Instead of saying the plants shrunk because you added soil...you could use the difference in the depth of the soil to adjust your plant heights so growth is consistent. If you need help with this, let me know! :) Happy growing!
Hi, today we added some dirt to are plants to help them grow and we replanted corn an radish. hopefully they start growing.
Hello! Today we have more plants and higher heights of the previous plants. We watered them and took observations. We only have the question about the soil. Thank you!
Hi! Our teacher noticed that there was not much soil in our pots. We were wondering what you thought. Do you think that we should add more soil? Right now we have 5.08 cm. Thank you!
Thanks for updating the info about the grafting and your journal updates. If roots are growing nearby or even twisting and twining together, they will stay separate to each plant. But, the degree of intermingling of the root structures might be more or less depending on the root type. A tap root...like a carrot might not intertwine as much as the corn, which is fibrous. Hope this was helpful!
How much water are you adding to each container? You have 20 or 60 ml listed. Does the soil feel dry when you touch the top or is it slightly damp? If the soil is dry you might have more plants germinate if you increase the amount of water for the next watering maybe add 60 or 100 ml (depending on how big your beaker is!) at a time until the soil is moist. Then repeat that amount for each of the remaining containers. Then at the waterings after this one just add a little water to keep it wet.
Are you having fun? How long will you grow the plants? Anyone willing to grow these until they make grain or pods?
Hello! When Mrs. Martin came she did talk about methods that she used to graft melons. We don't think that the plants will grow into one as if they were grafted. We do think that the radish and corn and radish and mung bean will compete because there roots will not grow well together because they are not similar. We also think that the corn and mung bean will not grow into one as if they were grafted but might try to grow together into one because there roots are similar. Thank you for the useful information! We uploaded our journals so that you can see our observations and measurements. Thank you!
