Updates
It looks like the problem is resolved and everything should be back to normal. Please feel free to resume posting, and do let us know if you experience any issues posting to your projects.
Hello everyone!
We are aware of some technical issues with the platform, leading to an issue with posting to project pages and issues with users' dashboards. We are working diligently with our developer to resolve them as quickly as possible. Please be patient and keep checking your projects so you can post your hellos, updates, reports, thank-yous, and goodbyes.
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. You have until Tuesday, April 25, 2021, to post ALL of your updates, comments, and goodbyes. 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
Hi team!
Great work!
In your data table, are the measurements growth since the last time it was measured or the total length of the sprouts?
Also, what were the condition of the stems and leaves as the experiment went on? Sometimes if a plant is not getting enough light it will grow fast and turn a whiteish color as it uses up it's stored energy.
Hi Kevin,
Over the course of the experiment we learned that the beans getting germinated under colored light did better than the ones under the plain sunlight. Somethings that were experimental errors we had were that some Petri dishes and peas got a bit dry at times and so we could have watered a bit more regularly. We also could have labeled a bit more thoroughly just in case. Thank you for all of you help over the course of this experiment!

Dear Kevin,
We have concluded the experiment.
We learned that the green light is the best, then blue, then red, and then normal light. Before, I thought that the normal light would do the best, but actually, it did the worse. The other part about the order of the colored light was all correct.
If I would have done it again, I would try to log more days. There were many days we missed. I will post the hypothesis and the graph.
Thank you so much for your guidance. You were very helpful.

Hello,
We learned so much from this experiment. Including the fact that seeds germinate faster with different colored light wavelengths! Thank you so much for your help. We couldn't have done it without you! One thing that I would do differently next time is to do more trials so we can get totally accurate information.

Hi team!
Thanks for your updates. Sometimes science takes patience. Another thing to keep in mind is that not all seeds will germinate. There are bad seeds. that's way replicating your experiment is so important. Hopefully adding some more water will help the others bounce back.
Hi Kevin!
This is our 4th time logging the experiment. We missed a few days. It seems like the peas need more water. Some of them shrank by a lot. So now, we're gonna do 30 drops on Tuesdays, and 40 drops on Fridays. The red one is doing the best. The green is the 2nd best. No new peas germinated. For the red, there is a 5cm radicle, 3, and 4 1/2.

Hi Kevin,
Today we watered all of the seeds with 30 drops of water. Still, only two of the control seeds have germinated, and the seeds that didn’t look shriveled and dead. The radicals on the seeds both measure 4 cm. All of the seeds were pretty dry so hopefully, the water will help them grow!
-Joseph
Hi Kevin!
Today the green light-box grew a little bit more. Some of the other peas from other colors are starting to sprout new radicals from the first radicals. The radicals from the green box measured 6, 4, and 2 centimeters. Today we also changed our watering schedule to 30 drops on Tuesdays and Fridays due to lack of growth and dry dishes.

Hi Kevin!
Today we watered our peas, they were looking dry so we did 30 drops of water today instead of 20. The blue ones are looking pretty good. Their radicles are 5, 3, and 1/2 cm. One of them is really small (1/2). We don't know why, but we do know that it has been bigger before. So either we measured wrong, or it is somehow shrinking? Do you know anything about that? We are working on our presentation for Friday, and we are almost done!

Hi Kevin!
This is our 2nd day observing the seeds! So far, the green one is doing the best, yesterday and today! (I made a mistake). We watered the seeds (20 drops). For the red, 3 out of 4 seeds have germinated. The one that hasn't looks dark green instead of beige. I don't think it will germinate. The radicles of the peas are 1cm, 3 1/2cm, and 3 cm. It is the 2nd best out of the peas. The normal one is doing the worst. How I know it's the best is I add up all the centimeters and see which one is the largest. Green has 9cm, red has 7 1/2cm, blue has 6 1/2cm, then the control one has 4cm.

Hi Kevin!
Today the green lightbox experienced some more growth, their radicals measuring about 2 1/2, 3, and 3 1/2 cm long. All of the colored boxes are growing faster than the normal dish, but this could be from lack of water or other variables. Today we also watered each dish with 20 drops of water. We will do the same on Friday.

Hi Kevin,
Today the radicals on the control peas measured 2 1/2 and 1 1/2 cm. We watered each set of peas today with 20 drops of water. Still, only two of the control peas have sprouted, but they were pretty dry so hopefully, the rest will germinate now that they got some water.
-Joseph
Hi Kevin!
Today we checked our peas again. The peas under the green light are now 2 1/2, 3, and 3 1/2 cm. Still, only three have sprouted. I am surprised and happy at how fast they are growing. With the new knowledge, we can now guess that since the peas radicles have each grown one centimeter, the peas may have sprouted on Saturday. Of course we can't be sure, but it seems like it is a strong possibility. Today we watered our seeds. We gave each petri dish 20 drops of water, and we put a drop of water on each pea to ensure that it had enough water. Any suggestions?
-Nora
Thanks for the updates! Seems like you are on your way to answering your question.
Hi Kevin!
To answer you questions, our prediction is on one of our posts, and we have 4 seeds in each petri dish. We are watering 20 drops of water on Tuesday, and 30 drops on Friday. We have checked on our seeds today, and every petri dish has 3 germinated seeds, except for the control. The control has 2 seeds. The red magna tiles have 2 1/2, 1 1/2, and 1cm radicles. The red and blue have that too. But, for the blue and green, the pea that has not germinated is strangely dark green. I think the reason why it was green except for the red, was because it is the darkest color out of blue, green and normal.
-Minyoung
Hi Minyoung,
Your prediction isn't how you are going to test your research question, but how you think things will shake out and reason you think that.
Hi Kevin!
Today we recorded our first data for our project. I am in charge of collecting data for the green lightbox. The peas in the green box had pretty average-sized radicals. They were 2 1/2, 2, and 1 1/2 cm long. The red box experienced the most growth.

Hi Kevin,
Today was the first day we measured the seeds. I measured the control seeds. Two out of the 4 peas germinated with the radicals measuring 2 cm and 2.5 cm.
-Joseph
Hi Kevin!
When we measured and checked our experiment, the peas put under the blue light had radicles that were 2 1/2 cm, 2 cm, and 1 1/2 cm. Three of the four peas sprouted. Our watering schedule is 20 drops of water on Tuesday, and 30 on Friday. Any suggestions? What do you think so far?
-Nora
Thanks for the updates and new picture. I like how the enclosures turned out. Make sure to check the seeds have water.
Any guesses on which one of the colors will be best for growing the plants? Also, how many seeds do you have per petri dish?
