It's been great working with you, Crazy Coconuts. I was excited each day in anticipation of your posts, and I was pleased that you were able to be creative about your projects.

I thought that your results were very interesting, although you didn't draw very many conclusions about the weight of the plants, only growth. As silly as this sounds, if I were a radish farmer, I would want radishes, and the bigger the better, and I'd care less about the above ground biomass. While you didn't have enough time for radishes to develop fully, I wonder if your weight data, where the control weighed more than both experimental groups, suggest that these control conditions would produce bigger radishes. It would be something to possibly test in the future.

I hope you all maintain your excitement and enthusiasm for science! Keep up the good work!

This session of planting science has been such a great learning experience. We would have hoped for better results but that is just what happens in an experiment. We all greatly appreciate the help and encouragement that you gave us and our project. In the end we could not have had a better more helpful mentor. 

Thank you,

Michael, Michayla, and Emmie

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!

Michayla,

I saw your post - the radishes did grow, but yours had not developed enough to be recognizable as radishes - they were still pretty young. They would have to grow longer in order to develop fully. 

Thanks for keeping me updated and letting me know you are finished with the experimental part of your project (and will be on vacay next week).

I noticed that you suggest in your conclusions that the warmer plants "grew healthier and taller," but is this statement actually reflected in your data? I agree that the cold plants performed less well than both, but, with the exception of the final 2 days, the control plants were taller (but not by much). Also, you noted that the control plants were much heavier than the heat/cold treated plants. Does this suggest that heat or cold was beneficial or not to the plants?

If you were to change your conclusions based on your presented evidence, what would you say?

Hi Steven, 

We have vacation all of next week. Just wanted to let you know because we will not be working on our project during this time.

Thanks, 

Michayla 

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 steven 

Today we dumped out our plants, unfortunately we had no radishes growing. We weighed the plants and the warm was 0.3 grams, Cold 0.2 grams, and controlled 1.6 grams. 

Glad to hear things are starting to wrap up for you. Thanks for sharing your data and figure with me. What does your graph tell you about your plants and treatments? It seems unusual to me that height decreases... I assume this doesn't mean that somehow your plants actually got smaller! Is this an effect of your plants dying or lodging too much?

Hi steven, 

Today is the last day of measuring. However, this will not be the last day of the whole thing.

Today we will update our journals as we do every Friday. Next week however is the last week of our project, so our conclusions will soon be written. At the moment we have been struggling to keep some of our plants alive. The nitrogen rich soil has caused them to grow up to 15cm tall, but due to this some stems have bent over the weight on the pants tiny stems. i think that one way we could straighten the plants would be to ask our teacher if she has any little straws that we could cut up and put around the plants stems. over the weekend the plants should end up watering themselves as they had the past two weekends so we are not completely concerned with watering them today. Hopefully all goes smoothly,

Michael

I'm glad to hear things are moving forward! It looks like you are seeing above-ground differences among your treatments, though perhaps not too much between the control and warm bin. Do you know how much longer you will monitor your plants before you pull them out and weigh them/look at their roots? I am curious to see if the roots actually develop into what we know radishes look like. If they do develop, you may consider measuring the size of the radishes... perhaps take a string, loop it around the widest part of the radish, and then measure the length of the string. Just another suggestion.

I was also elated to hear of each of your interests. The common theme among them for me was that you all understand and are interested in the idea that plants are living organisms that respond to differences in their environments just like animals do (it's just that plants don't move... which actually creates a special problem for plants - for example, they don't go from one place to another to find good temperatures for growth and development)! 

Steven,

Today we did the normal stuff. We measured, watered, and got the temps.

Soil temperatures:

Cool soil- 23.3 degrees celsius

Normal/ controlled- 26.1 degrees celsius

Warm soil- 30.9 degrees celsius

The reason the plants were a little warmer was because the ice packs melted, and it was very warm out the past 2 days.

Hope to hear from you soon,

Crazy Coconuts 

Steven,

This project is very interesting to me. I think that what interests me most is learning what different plants need to live and be healthy. Since I want to be some form of scientist when I grow up, the whole experiment is pretty exciting to me.

Emmie

Steven,

Thanks, we ave been rolling smoothly since the watering problem cane to a conclusion. I'm not sure if anyone has told you yet but we are only going to water our plants when they have to be watered from now on. 

Right now I am most interested in why our plants are growing so so tall. The warm and controlled bin are over 10 cm! After all this is not normal fr radish plants. When I took research on why this was happening, I found out that the soil we are using is super rich in nitrogen. When plants get to much nitrogen they tend to grow tall  and are more open to infections. See you on Monday.

Michael

Hi steven its Michayla 

I am interested in the cold bin. It is pretty common that the warm and controlled bin would grow, but i didn't think that the cold bin would grow at all and it did! Lately the cold bin hasn't been very cold. Do you have any suggestions on how to make it colder? 

Steven, 

Today the temperatures were closer than usual.  

Control- 20.6 degrees Celsius

Warm- 23.3 degrees Celsius

Cold- 17.3 degrees Celsius

It may be due to the fact that the light bulb for the warm bin went out, but it was replaced. We got more snow for the cold bin also.

To answer your question, we do think that we could weigh the plants in the end.

- Emmie 

Hi Steven!

There is a difference in the warm and room temperature bin, the difference in temperatures is one. Another thing is there seems to be more growth in the warm bin.We are not yet sure when we will be ending the project

- Michayla

Turns out our plants absorbed a lot of moisture from their bins over the weekend. When we watered them they were super soggy, and were in a pool of water. Due to this we decided to drain the plants so that they do not drown. The cold bin temperature went up over the weekend, but that is to be expected because the ice packs melted. We finally gt a sprout in our cold bin, and the other bin's plants are climbing up to nearly three inches tall. Just keeping you updated.

Michael

Hi

We have been collecting the temperatures and the average height in each bin. We have no plants in the cold bin. Today the temperature in the cold bin has almost doubled in temperature.yesterday it was 9.9 degrees celsius and today it is 16.2 is that ok? 

Michayla 

Steven, 

Today we have sprouts in the controlled bin and the warm bin. The temperatures in the soil were 9.9 degrees celsius (Cold), 21.3 degrees celsius for the normal one, and 33.6 degrees celsius for the warm one. We are rotating the cups so that they get equal amounts of light.  Thank you for your opinions,

Emmie

You may also want to consider rotating your cups each day. Based on your photo, it looks like the light source is more under one area than another. This could mean that the soil directly above the light gets hotter than the soil farther away. Be consistent where you are measuring soil temperature (may not be in the same cup if you rotate them, but should measure in the same spot within the bin, e.g. the soil over the light).

However, because of the light source so close to our plants, the light will have to be shut off more often. This means at night, possibly short periods during the day, and weekends. (The weekends one would have to happen anyways... fire hazard.) Still this should increase soil temperature more rapidly.

Michael

Hi Steven. 

I know the main focus for our project is seeing how the soil temperature effects plant growth. When we see the end result should we do the average temperature for the whole project in each bin.

Thanks Michayla.
