Project by group sffsporterspring2019

Info

Explore Work on this next!
What do we know about plants from our experiences outside of school? What have we discovered in class and background research? What questions about plants interest us?
Research Question If the quality of the water changes, will it affect the rate of germination?
Predictions If we Change the quality of water we give to 5 different Petri dishes of Ryegrass, then I think the Ryegrass will do best in the Petri dish with pure water (ph=7) or black coffee (ph=5)because Ryegrass is best in a ph of 5.5 to 7.5 water/soil
Experimental Design Soak 50 ryegrass seeds overnight Lable 5 Petri dishes with numbers 1-5. Put 2 layers of circled shape paper napkins in the petri dish. Put ten ryegrass seeds into each Petri dish and make sure that they are spread out and can’t get under the paper towels DO NOT WATER THEM YET. Only spray...
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?

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 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

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.

Toby, Kai, and Jaxon,

Thanks for being such great scientists and letting me join in your project. I hope you all learned some cool things and are excited to learn more about the natural world! Good luck in the rest of your school year:)

Like we predicted the coffee and the water were the best Petri dishes out of all of them, in fact they were the only Petri dishes that started to germinate. Out of these two Petri dishes water probably did the best because in trial one the radicals of the Petri dish with coffee just stopped growing after a 2-3 mm. A quantitative observation that surprised was that on day 5, trial 3 some of the radicals in the coffee petri dish were 20-45 mm. A Qualitative observation I made on day 1 of trial 1 was that some old the seeds broke out of there seed coats.

Hi Mason,

at the end of this experiment the most successful trial was trial 3 because the coffee grew. thank you so much for helping us the tips you gave us was great. and the link of what will happen if you spilled soda on plants helped me. Thank you Mason.

sincerely Kai

Our experimental question was, if the quality of the water changes, will it affect the rate of germination? Our hypothesis for the question was If we change the quality of water we give to 5 different Petri dishes of ryegrass, then the ryegrass will do best in the Petri dish with pure water or black coffee because Ryegrass is best in a ph of 5.5 to 7.5 water/soil. Our data supported our hypothesis. One example of qualitative data that supported our hypothesis is we had was, in every trial except number two we had the coffee germinate first. This anomaly may be the result of me not watering the right liquid into coffee. This makes me think since the liquid I watered the seeds with was soap then soap must be really terrible for plants. One example of quantitative data we had was that water and coffee in trial two and three were germinated by the second day. Overall this was a great experiment that tested organization and strengthened teamwork. I wish to have more labs like it.

    Here's the spreadsheet if you choose to use it. It's already labeled with everything. Also let me know if you'd like help making a graph.

Hey team,

It sounds like you guys are wrapping up your report and getting pretty interesting results. While coffee treatment seems to decrease germination, the difference in trials is definitely something to talk about!

As you guys start coming to conclusions and discussing the reason for your results I'd like you guys to consider making a graph of your data. Quantitative figures are the backbone to science communication and would really strengthen your results. I've attached a spreadsheet you guys can fill out with your data. If you need help making a graph, you can send the spreadsheet back to me filled out and I can make a graph from it. Let me know if this is something you guys would like to do. 

As usual keep up the observations/measurements/pictures:) Good job everyone!

Hi Mason,

today in class we looked at our trial 3 coffee and it is growing a lot. so far in the other trials coffee hasn't grown one bit.

    Hi Kai, 

    Nice pictures. It sounds like pH is a huge limiting factor in germination. I wonder does caffeine affect germination too? I wonder why the other trials haven't germinated compared to trial 3? Interesting things to think about, and consider writing about as you guys wrap up your report:)

Hi Mason,

I just updated the project!

Today was the 2nd day of trial 2 and the 1st day of trial 3. Something interesting that we noticed was that only trial 3 seeds sprouted and none of trial 2! We do not have an eplanation for this because we tried to greet the different trials the same way. In trial 3 about 16ish have sprouted there radicals, 10 of which are just plain water. I predicted like trial 1 the coffe sill stop growing after about the length of 7ish mm. Do we write the conclusion after all our trials or is it like another prediction?

    Hey Toby,

    Nice joke earlier, I tried to make a pun in my response but don't know if I was successful lol.

    Thank's for updating the info:) and that's great you're doing multiple trials. More trials = more confidence in results! That's curious that you trial 2 seeds aren't germinating but if the control treatment (I'm guessing water is the control?) aren't germinating either then you could speculate that those particular seeds were affected by a possible external factor that you didn't account for (those seeds are duds, they were exposed to unfavorable temperature, etc.). 

    Lastly, now that you're wrapping up your project you can start to make conclusions and discuss why you got the results you got. Here's what you should talk about...

    1. Why do you think you got your results (sounds like pH is a huge factor but why does pH/coffee affect those particular seeds?). 
    2. What other factors did you possibly overlook? (caffeine in coffee, temperature, amount of liquid, light, etc.)
    3. What would be a good future experiment now that you know the effect of coffee on seeds (for example: mechanisms of how pH reduces germination, comparing the effect of pH on different types of seed, etc.)?

    Sorry for the long response, but hopefully all this info helps you guys write up a nice report.

    OH I forgot to mention, in your discussion, it is very important to discuss why your results matter! What does this mean for people who grow ryegrass? Why is pH important for plants in general? 

    Good luck!
