Info
| Explore | Some research that we did was to figure out what temperature best germinates the cilantro seeds based on our research it showed the 13-18 degrees celsius best germinates herbs. This helped us pick two of our five temperatures. |
|---|---|
| Research Question | What water temperature with best germinate the cilantro seeds? |
| Predictions | The room temperature water will best germinate the seeds. The colder water will germinate the seeds better than the hotter water. |
| Experimental Design | Our plan is to put the seeds in petri dishes so we can see when they germinate, we will make sure that our water temperature is at the temperature that we want which is 5, 10, 20, 35, and 50 degrees Celsius. |
| Conclusion | Our conclusion was that our hypothesis somewhat supported our first trial and did not support our second trial. In the first trial, it supported the experiment because the 10 degrees celsius ended up germinating the cilantro seeds better than the 35 and 50 degrees celsius. The 10 degree celsius... |

This group did a great job of designing their experiment and understanding the importance of multiple trials. They ran several trials of their germination experiment first and noticed some inconsistencies in data, so they ran several more trials of each variable. They worked well as a group... |
Updates
Hi Jessica, I wanted to update you on how our plant project went over these past several weeks. Overall, both of our trials gave us relatively the same results. The petri dishes that contained seeds that were watered with extreme temperatures (5 degrees C and 50 degrees C) showed the least amount of growth throughout our experiment. The petri dishes with the seeds that were watered with more moderate temperatures (10 degrees C and 20 degrees C) definitely showed the most growth and change during our two trials. We would all like to thank you for your help and great ideas throughout these past few weeks! Your opinions and thoughts truly helped us to improve our experiment and understand more about what setting up an experiment is like- as well as what should be included in it. We're really glad we had someone like you to help and guide us along the way. Thank you!!
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.

You have until Tuesday, April 25, 2021, for final posts to be added, so please be sure to thank your fellow teammates soon!
Jessica, thanks for the ideas! We have also started a new (second trial) late last week, and our results and observations are very similar to those of our first trial!
That's excellent! We love to see the same results in multiple trials. It means that you all had excellent technique and were able to replicate your work. That's very important in science.
Great job team!
Hi Jessica, our group has made a google doc where we add information for every temperature group each day. There was more than one temperature that germinated first. For the first two days we tracked, no seeds germinated at all. On the fourth day, however, we had seeds germinate from at least one petri dish in all of our temperature groups. Certain temperatures had just one dish germinating while others had all three, and some had more seeds germinating within each dish. I will upload a couple pictures so you can get a visual of how our experiment is set up and what it looks like!
That's very interesting! It's very common in science for things not to go the way that you expect them to. Especially with plants, they have a mind of their own. Since there wasn't a clear "best" temperature you can do a few things to select the "best". You can either measure the growth and calculate the average which might be the easiest. Or you can create a scale. For example, day 4 sprouting is worth 5 points then day 5 is 4 points, and so on. Each seed that is germinated gets the points corresponding to when they germinated. The temperature with the most points is the "best" temperature because the seeds germinated faster.
Great work!
Hey Jessica, here's an update on our project: A few of our seeds have started germinating in some of the petri dishes. We currently have seeds germinating from each kind of petri dish, except for the 50 degree dishes for which the seeds have barely started growing yet. The 10 degree temperature dishes have the most seeds that are germinating.
That's very interesting results! Which temperature group germinated first?
Do you know how you will organize the data that you are collecting into a visual format?
Hi Jessica, so far we have set up 15 total petri dishes with 3 petri dishes of each temperature. We put 10 cilantro seeds in each dish and watered them with the correct temperature. We will be measuring based on time- how fast it takes the cilantro seeds to germinate.
I like the different temperatures that you added to the project plan. I think this adds a lot to the project. I'd still love to hear how you plan to determine the "best" temperature. Are you measuring it based on time or length?
I took a look at your research proposal and I had some comments to improve it. Instead of having 3 different temperatures, have 5 different temperatures. These groups would have 2 extreme temperatures, 2 moderate temperatures, and the 1 room temp. If you are truly looking at how temperature effects the growth of seeds then you need more data points. Typically in science there are 3 biological replicates per group as well but that depends if you have enough seeds to set that up. But just having one replicate per group is sufficient. Are you using tap or bottled water for this experiment? That should be stated in the proposal.
Your hypothesis stems on the definition of "best". How will you be determining which is best? Are you measuring the growth and the most growth is the best? Is it the fastest to germinate? Or is it the most seeds to germinate within a designated time? You can make your hypothesis more specific to which criteria you will be using. e.g. 70˚F water will be the fasted to germinate.
Great work so far!
Hi Jessica, we're not exactly sure what our final research proposal will be yet, or what kind of seed we will be using. We should have a final idea with details ready by the end of this week. Thank you for your feedback!
Thanks for the update! Let me know when you know more :)
Hi Jessica! As a team, we've come with two potential ideas for our research project. One idea we came up with was to test each plants growth with different types of soil. Our second idea was to test each plants growth with different temperatures of water. We still have yet to figure out the measurements and details, as well which idea we plan to go with. Please let us know your thoughts, thank you!
Those are both great ideas! They are very important criteria when investigating seed germination. Different plants have different requirements for growth so it is always good to know which one is optimal for the specific plant you want to grow. If you look at different types of soils, do you mean sandy, clay, chalk, or loam soil? Or are you thinking more of the nutrients in the soil from commercial soil bags. If you are looking at water temperature, you need to make sure to use the same water source to eliminate other variables (same bottled brand vs tap water).
From my understanding, you will be watching your seeds germinate without changing any variables and then going ahead to design a project with independent and dependent variables. Is this correct? Also do you know what seeds you will be using for the project yet?
Hello Jessica! My name is Nicole and I am a junior in highschool. My favorite hobbies include working, playing volleyball, reading, and spending time with my friends outside of school. My favorite plant would have to be roses, because they come in many different pretty colors! What is your all time favorite book/book series? Also, how did you decide what you wanted to research while you were in college?
Hi Nicole! I love Tuck Everlasting, the City of Ember series, and the Mortal Instruments series. From the end of senior year in high school until junior year of college I wanted to work in pharmaceuticals specifically cancer. I have always loved doing experiments in school and in my free time so I knew I wanted to do research. When I took organic chemistry it was really hard and I didn't love it which you need for pharmaceutics. But then I took a genetics course in my junior year and fell in love with genetics. Working with plants kind of picked me instead of me picking plants. I had an opportunity to work on a project about the genetics of a plant bacterium. From there I could choose to work on human molecular genetics or plant virus genetics for my masters. I loved everything I learnt about plants during my old project so I wanted to continue working with plants. Now I am even looking into doing a PhD with plants :)
Hello Jessica! My name is Ryllei and I am a Junior in high school. I love playing soccer in the summer and going to museums. My favorite type of plant are sunflowers. Are there any books you never get sick of?
Hi Ryllei, I love sunflowers too! I own so many books that I haven't read yet and I keep buying more. I am currently trying to work my way through all of my unread books. But I read this book in grade 4 for class (it's not a very sophisticated read) but I still love the book. It's called Tuck Everlasting.
Hi Everybody! I'm Jessica, and I am a Masters student at Brock University and Agriculture and Agri-Food Canada located near Niagara Falls. A bit about my research, I am studying the viral implications in an emerging disease affecting stone fruit trees in the Niagara region. I also investigate genetic variability in Tomato ringspot virus (plant virus) and its prevalence and distribution in fruit trees.
After studying plants so intensely, I am finally starting a collection of plants of my own. In my limited free time, I tend to my plants and read. When it is not the dead of the winter I enjoy hiking and being outdoors.
I'm so excited to work with all of you this term! To go with the theme, I have a question for you guys too. What is your favourite plant?
My favorite plant is probably lavender because of its color and smell! Pine trees are a close second.
Riverdale and All American are my favorite TV shows
Hi I am Cheyenne
I am a Junior in high school. I really like to be in musicals and to sing in choir.
Who is your favorite singer and what is your favorite TV show to watch?
Nice to meet you Cheyenne. My favourite singer is Demi Lovato right now. I have quite a few TV shows that I could rewatch 10 times and still love. My top 5 are Grey's Anatomy, House, Gilmore Girls, Friends, and NCIS (the original). And no I cannot pick an all time favourite. What is your favourite TV show?
Hello my name is MacKenzie!
I am a Junior in High School. I play Volleyball, Basketball, and Track. I enjoy Curly Fries from Arby's!
What is your favorite thing to do in the winter?
I played volleyball in high school too! I still love it but don't get to play much anymore. Nice to meet you MacKenzie. In the winter I love skiing when possible but I think my favourite thing is ice skating outdoors!
Welcome to a new session of PlantingScience! I am the liaison for this group, and my role is to facilitate the conversation between this group of students and your mentor when it is needed. Other than being your liaison, I am a graduate student at California State University, Fresno (Fresno State). For my research project, I’m looking to see if virtual field trips impact how interested students become in STEM (Science, Technology, Engineering, Mathematics) subjects. In the past, I have worked on plant projects too! I look forward to working with you all!
Best wishes,
