|Research Question||We want to test how crucial water is to plants. We want to learn the side effects of adding the appropriate amount of water, little to no water, and more than enough water to the radishes. How does the amount of water in the soil affect the growth of radishes?|
|Predictions||Radishes that receive little to no water will eventually stop growing, radishes with too much water will result in drowning and rotted roots and radishes with the normal amount of water will succeed.|
|Experimental Design||Procedure 1 Find the adequate soil type for growing radishes (Deysi) Sandy or Loamy Add the same amount of soil to the 6 containers Get 6 containers of the same size and make sure they are clean. (Fatima) Wash containers before filling them up with soil. One partner will then fill up the...|
|Conclusion||What claim can we make from our experiment? What are possible explanations for our results? How do the data we collected and our reasoning with scientific ideas support our claim? What future experiments could be done to expand on the results of this experiment?|
|About this Project|
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. Please come back and visit the https://plantingscience.org/projects/browse”>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
Thank you so much for continuing your PlantingScience work during the pandemic. You've all done some amazing work! We have made it to the final week of our session so it is time to start wrapping up your projects. Please share your final reports or conclusions with your mentor this week. They are excited to see how your experiments turned out! Don't forget to thank your mentors as well for their help!
Stay healthy and thank you again,
The PlantingScience Team
Thank you! It was really nice working with you. Take care and stay healthy!
I wanted to take a moment and reach out to you, in light of the current COVID-19 crisis. I know that there is a lot of uncertainty and fear going around right now, and it is perfectly natural to feel that way. Your lives may be disrupted, and your experiment may not be as much of a priority. As scientists, we are only human, and it is a normal part of the scientific process for life to get in the way. Go easy on yourselves during this time, and focus on staying safe and healthy. You learned plenty from this project with the amount you were able to accomplish, and I was genuinely impressed with how prepared you all are for careers in science. I am sure that you will all succeed in your chosen fields, and that your experience with science will continue to serve you well. Stay safe!
Your mentor is excited to review your reports!
Please share files (Word documents, Excel spreadsheets, Power Point slides, images) in the "Files" tab to the left of this text area, but remember to EXCLUDE last names, email addresses, links to Google or Sharepoint documents, and social media handles.
Thank you for your cooperation!
Great job on the photos! In your most recent pictures, you can see that the new leaves have a different shape and texture than the first few leaves. The rest of the leaves that your plants grow will look more like these new leaves. I am curious: what sort of soil mixture are you using? I noticed as I was looking through the photos that it looks really nice, but it is different from what I have at home.
Keep up the good work!
Hi Team 12,
I will look forward to your slideshow! It sounds like you've been very consistent in your methods so far. The records you've been taking both here and in class will help you to be more confident in your conclusions at the end of the project. Great job!
We have noticed that there has been some changes in the seedling sets. We have taken a few pictures of when the plants first started growing. The project is going very well and we are also being consistent on watering the plants everyday. By the end of this week we will be providing you with a slideshow with information on our plants growth.
Now that you're back in the classroom for the week, have you noticed any changes between your seedling sets? My favorite part of growing plants from seed is when the first true leaves start to emerge. The cotyledon, or embryonic leaves, are those first little ones that pop out. You may notice that the true leaves are more complex in shape than the cotyledon. I like to take pictures of the leaves while they're still little, so I can look back at how big they eventually grow. I hope you'll take some time to enjoy the small parts of your experiment this week.
Our prediction was that set 1 would take longer to germinate and not grow as big as set 2 that is receiving the correct amount of water. But set 1 germinated right after set 2 and the plants are growing big. We thought set 3 wouldn’t grow because they are receiving a lot of water but it just took longer for the seeds to germinate.
Hello Deysi, Abel, Monserrat, Fatima, and Roberto,
Your watering schedule sounds great; you have plenty of variation between the groups. As you progress through your project, keep your predictions from the beginning in mind. You can already see a difference in the rate of germination between groups. Is it what you expected to see? Is it somehow different from what you thought? As the plants continue to grow, you may change your mind several times about which set you think will be the most successful. It can be helpful to make a short note whenever that happens, so at the end of the experiment you have a log of both your observations and how they influenced your thinking.
If you have any questions about your experiment, or plant science in general, please let me know. I’ll look forward to your next update!
It’s going to be a pleasure working with you! Gladly our school does offer some amazing programs that help its students expand their knowledge in agriculture. Thank you for your advice in just concentrating on how water affects the growth of the plant. Now that we have discussed among us, it would be complicated to determine what is affecting the growth of the radishes.
Set one is receiving 500 ml of water Monday through Friday. Set two is receiving 500 ml of water every Tuesday and Friday. Set three is receiving 500 ml of water in the morning and another 500 ml of water in the afternoon Monday through Friday.
A little update about our experiment is that today the two containers for set 1 and set 2 the seeds have already germinated and only one container from set 3 has germinated. The average height for our seeds from set 1 is ¾ inches, from set 2 is ¾ inches and from set 3 is 9/16 inches.
My name is Tracey, and I'm an ecologist doing research in a botany lab at San Jose State University. I'll be one of your mentors on this project, and am looking forward to working with you. I'm not a PhD (yet!) so please feel free to use my first name when we chat.
The agricultural programs available at your school sound so cool; I wish my high school had classes like these! Its clear that you had a good idea of where to start with your experiment. In regards to soil temperature, it is possible that it would affect the growth of the plants. Your main question is about the importance of water to plants, so it might make sense to keep the soil temperature the same for all of the plants. That way you will know that temperature is not the cause of any variation between the groups. If you test for more than one thing at the same time, such as testing for both temperature and water amount, it can be difficult to know which of the things is really causing your observations.
I just want to double check: are you currently giving all of the sets 600ml of water each, or are the different sets currently receiving different amounts of water?
Looking forward to seeing your progress!
Hello Dr. Rodriguez,
It’s going to be a pleasure working with you!
A little update about our experiment is that today set 1 and set 2 the seeds have already germinated and the seeds from set 3 have not. The average height for our seeds from set 1 is ½ inches and from set 2 is 10/16 inches. We are watering 600 ml of water to each of our containers. Should we consider testing other aspects, for example soil temperature?
Thank you for presenting yourselves, I am pleased to meet you!
I am Aline Rodrigues de Queiroz, a PhD student in Biochemistry at the University of Nebraska-Lincoln. I do research on various aspects of plant physiology and development.
I will serve as your liasion and I look forward to starting working with you!
I am glad you guys already have a plan for your experiments. Some things to consider:
I loved your experimental design! Just be careful with the amounts of water you'll use, I would actually measure them and keep it constant across your treatments.
