| Explore | 10/30 - Radish seeds need a moist soil enviorment but you can't over water it. You need to water is every other day but you can't over water it. Watering it everyday can lead to the plant possibly dying. You also have to plant the seeds an inch to half an inch apart in order for the roots to... |

| Research Question | For our independent variable, we are testing the amount of water that we put into our plants. We're going to see how the water is going to effect the plant growth. We think that a little more water will grow faster but if we add too much, that could kill it to. If we don't add enough water, that... |
| Predictions | Working Hypothesis: If you water the pearl millet seeds a medium amount of water, then it will grow to its max height possible. Hypothesis: If we water the pearl millet seeds 40 mL of water, then it will grow to its maximum height. |
| Experimental Design | 1. Germinate seeds using a paper towel, water, and a plastic bag and wait until tiny sprouts grow, water if necessary Germination Process Steps: 1. Take paper towel around 30-36 centimeters long. It depends on the bag size. 2. Fold it in half and put it in the bag. 3. Take 10 mL of water... |
| Conclusion | Unfortunately, our hypothesis was not correct. But, that’s okay because a hypothesis will not always be correct. Turns out, the bottles with 60 mL did the best when we assumed it would be the 40 mL. We thought that 40 mL would be your “medium amount” of water but it turns out that 60 mL of water... |

The students of group 3 always try their best to explore scientific points and use to make predictions as per their observations. |
Updates
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.
We will be archiving groups and projects on December 17, after which time new posts will not be able to be added. Please come back and visit the PlantingScience Project Gallery anytime to view this project in the future. You can search the Gallery by key word, team name, topic, or school name.
Good bye for now.
Warm regards,
The PlantingScience team
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.
This is really meant a lot to me. This is morning here in Pakistan and i just woke up ... Reading your comments and compliments.... You really made my day. So sweet of you all. I couldn't explain how much i enjoyed with you all. The way you were investigating your observations and making predictions was marvelous. I also want to say a big thanks to all the stars of "the dark four" and your great teacher. You all are wonderful and amazing. I wish you all the brightest future ahead and many warm wishes for your Christmas.
Keep on rising and shining and stay blessed. Love you all.
Good bye
Amina,
Thank you so much for all the help and advice with our planting project. Sorry that we could not take a picture of our plants. Our teacher recently mention that we were one of the "star groups" and I feel like that would not have happened if we hadn't got your support and mentoring. With all the advice on everything we really have strived and our plants have as well. We tried to do our best on this project and not only was it fun but we also got to meet a great mentor and scientist that helped us along the whole way. We will not forget you and all your help.
For the last time,
Astrid

Hi Amina,
Our plant phase has officially finished. We aren't quite done with Surviving the Zombie Apocalypse and continuing to work on it for the next couple weeks. Our teacher recently told us that we were nominated for one of the best groups in Planting Science. We were one of the "Star Group Project" acording to our teacher. We just wanted to say thank you for all that you've helped us with and the advice you have gave us. You have been such a good mentor and so supportive. From all the adivce that you have gave us and the encouragment to keep going, we thank you. You influenced us to think deeper and go more into the investigation. Most importantly, you have been a good friend too. Thank you again for all you helped us through and with. This wouldn't have happened without you. We strived for greatness and surely got there. We probably won't be talking again but we just wanted to say bye and thank you. We can't express how thankful we are. Thank you again from The Dark 4. Bye. Hope you have a good Christmas and New Year. Live life to your greatest potential. We're always rooting for you and won't forget you! Bye now.
For the last time,
- Kate

I am thankful for all your help thanks again BYE:(
Hey Amina- I just wanted to say thanks for all the amazing advise on our project. I know that I didn't posted much but I just wanted to tell you that we are thankful that you helped us with our project and because we used your advice we are a star project thanks. Bye Aidan W.
Sounds great, in conclusion, you consider 60 ml water supply to be an adequate amount.
Kate, I want to see the images of your germinating plants.
Sorry Amina, we already disposed our water bottles into the garden. We got rid of them a few days ago already. Sorry again.
Hi Amina,
Sorry we haven't been on for a long time. We had to get rid of the waterbottles and plant them on our garden. Our prediction originally was that 40 mL bottles would have the best results. We assumed that since the soil was moist, it would do the best. Turns out that the 60 mL bottles did better. We thought we were drowning the 60 mL but it turns out that we were just watering it too fast. We think that if we water the peral millet seeds a little more water than necessary, then it will grow better. The 60 mL also were the only plants that started sprouting leaves from the stems. We lost a few seeds from the other plants and they didn't grow leaves either. Our original hypothesis was wrong and turns out that the 60 mL would do better.
Today we started talking about water filtration systems for surving the zombie apocolypse. We need to figure out how to filter water with sand, gravel, clay, a cheesecloth and cotton balls. We are learning the process of filtration and taking notes on it today.

Thank you for the detailed updates.This is what we called research. The planting seeds now leading you towards learning of water filtration.
Also update the information in above columns of experimental hypothesis and design.
Hi Amina!
We're just giving you a heads up that we're back from break today. To answer your question, the 20 mL bottles didn't have as much growth. We assumed this because most days, the soil was really dry. We lost some plants and we actually don't know where they went. It's like they dissapeared. Do you have any idea what could have happened? It also happened with our 40 mL bottles. The 60 mL bottles did fine and did the best out of all of them. Thanks again.
- The Dark 4
Welcome back, I hope you had a wonderful thanksgiving break.
So, it seems like your seeds need an adequate amount of water to grow properly. When seed is not provided with proper amount of required water, it fails to germinate. See, in your case, seeds in bottle with 20ml water supply failed to germinate due to drought stress. Drought means the dryness of soil or absence of required water quantity.
Can I have an image of these three experimental bottles. I would also like for you to make a prediction/ hypothesis on the basis of these results.
Hi Amina,
Today is our last day. We've seen some really good growth but we might have to change our hypothesis because today, we actually saw more growth in the 60mL bottles. Today is also our last day at school. We're going to Thanksgiving Break next week and won't be on. Hope you have a good Thanksgiving!
- The Dark 4
Bye for now!
Sounds good. You' re making predictions on the basis of your observations. What about the growth of plant in 20 ml water supply.
Thank you for sweet wishes. Have a wonderful break.
Hi,
Just yesterday, we watered our plants and we noticed the 60 mL plants are literally drowning. The water didn't subdue very quickly and we're concerned that the plant is going to die. The 20 mL seems really dry but the 40 mL, the plants are thriving. We're just updating you on yesterday's observations. We'll update you again sometime today if there's any drastic change.
-The Dark 4
Hey Amina!
So, we're on day 2 or 3 of our growth experiment. We have confirmed that most of our plant grwoth comes from the cups that we watered with 40 mL. The 20 mL seems really dry but the 60 mL seems too wet. The 40 mL seems just right. We've been trying to send a picture to you but we haven't quite found a way yet. A lot has changed since we planted them. We'll update you again tomorrow if we see a drastic change.
- The Dark 4
Hello!
So yesterday, we officially planted our seeds. We filled the water bottles with soil and put the seeds in. We watered each of them the assigned amount of water and left them out under the sun. Today, we saw a small growth in some of the plants. The bottles with 40 mL of water seemed to grow the most so far. We're missing a few of our sprouts from the 20 mL and the 60 but we are watering them again tomorrow. We skipped today. Do you think we should water them more since we'll be gone for a 3 day weekend? We don't want them to dry out or die for that matter. Thanks for the help.
-The Dark 4
Sounds great. You got sprouts in bottles with 40 ml water supply. You are now going towards optimization of water quantity. If you think the soil will be dried out you can apply water in more quantity.
Hey Amina,
Sorry, we haven't updated you sooner. Today we started germinating our seeds and setting up our experiment. It's just like the germination we did with our mystery seeds earlier this year. Turns out, our teacher lost the radish seeds somewhere so we have to start planting something else. I don't remember what it's called but I'll get back to you on that one. Our first official day is tomorrow. We'll update you tomorrow on the germination if there is any. Any tips on planting for us that could be useful? Thank you.
- The Dark 4
good luck !
Yes, we are measuring the amount of water we are putting in. We have an idea on how to set this up and we'll try to attach a picture or something. Heres our brainstorm:
Trials: 5 radish seeds per waterbottle = 5 trials for each amount of water
Levels: 20 mL, 40 mL, 60 mL, - 3 bottles
- Same amount of soil in each.
- Water every other day with the different levels of water.
Dependent Variable: The height of plant
Materials:
- Soil
- Water bottles
- Water
- We'll continue adding more as we go.

sounds great. Looking forward to hear the further updates and pictures.
