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 | What do we want to test or study? How did we come up with the question(s). How does the question fit what we know about the topic? |
| Predictions | What are the possible outcomes of our study given the variables we are working with? What is our explanation for why and how we think this will happen? |
| Experimental Design | What is our plan? Be sure to include enough detail that another group can replicate our experiment. What variables will we test? What variables will we measure and observe? What variables will we keep constant? How will we record our data? |
| 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 |
This team consistently shared enthusiastic updates about the progress of their experiment and seemed to genuinely care about understanding the plant growth differences between their phyB mutant plants and control groups. In addition, they uploaded photos of their experiment on a nearly daily... |

Beautiful poster, team FISH! I hope you're all very proud of this work. Great job and Happy Thanksgiving!
Susan (Dr. Bush)
Thank you!! We will present tomorrow!!
Dr . Bush, I'm very upset that our experiment is coming to an end, first and foremost I would like to thank you for taking time out from work to help us and make our experiment be successful. You have helped us from the start not only did you help us by educating us about our plants but you also sent us articles that would help us and you also responded very quickly which was very helpful! I'm sure our group (FISH) would've been totally misguided and upset when we came to see that our Cotyledon variable was a bad decision. And without you we wouldn't have known what to do. Thank you so much for your help once again Dr.Bush! We'll make sure to upload a rough draft of our poster so that you can see our amazing work that you helped create! I hope you have happy holidays and an amazing rest of the year!
Hi Safa,
Don't cry! You'll enjoy your next project too I'm really happy that you all learned so much and I'm impressed that you're such terrific plant growers. I will be looking forward to seeing your amazing poster. What makes my job fun is you, asking questions and finding answers (and more questions) and drawing graphs and making posters! So keep up the good work. Happy Thanksgiving!
Susan (Dr. Bush)
Dr. Bush, as this project is comes to an end, I would like to thank you for helping us with our planting science experiment. In the times when we didn’t know what direction to go in, you were there to guide us. I am so grateful for all the information that you supplied, you made us think more in depth into the topic by telling us which questions to ask ourselves , like how you told us that the measurement of the plant color would be a great way to collect data on how the light has impacted the plants, which helped us so much into perfecting the experiment. You have encouraged us along the way which boosted our moral and motivating us to move forward. Again, thank you for all of the insight and providing us with your expertise within this field of science. Thank you for all of your work and for being such a great mentor through out this whole experiment. Happy Holidays :)
Of course, Itzel! I'm happy I could help you with the project. You knew just what to do with all the information you were getting and questions that were coming your way - really nice work! Thanks for working so hard on this project. Great job!
Susan (Dr. Bush)
Dr. Bush, our project is coming to an end! :(( Before anything, I would like to thank you for welcoming me into this group after mine had fallen apart. The time that you had put in, to help us was just amazing and without it I know that we would be completely lost! From the beginning you help us by explaining more about our plants, sending over other articles that we had not yet seen or just stating what you had found. Making suggestions to our experimental design, that we ourselves had not thought of, helped us see things "outside the box". The communication that had in a large part had been me, on behalf of Team FISH, you had been very responsive and always responded within a 24 hour period, which in itself was very helpful!! Once again A BIG THANK YOU FOR ALL OF YOUR HARDWORK AND TIME PUT INTO THIS PROJECT!!! We will try to upload a rough draft of our poster, that will be presented on Tuesday. If we do not communicate again, have a happy holiday season with the upcoming holidays and a great 2018 year!
Hi Filip,
I'm happy you found group FISH - without you they would just be ISH! But you all worked together very well (it seems to me) and I hope you're very proud of the project you put together! Beautiful graphs, beautiful plants, beautiful science. Great work! I'll be excited to see your poster of course. Happy Thanksgiving and good luck with the rest of your school year!

Dr. Bush, as this project comes to a close, I would like to thank you for taking time to help us with our experiment. Without you, we would have been lost! Thank you for suggesting the statistical data as well as explaining our actual mutants to us. You also suggested experimenting with the ziplock bags (even though that did not entirely work out) and I really appreciate that you were thinking of ways on how to make this project better! Whenever you asked us questions, it encouraged us to think deeper into the study and we have you to thank for that! This project went by incredibly fast; it seems as if we just started last week! I'm glad we got you as our scientist mentor and I hope that you enjoyed this experiment as much as we did :)
You're very welcome, Heba! I have definitely enjoyed working with you. I'm impressed by your hard work and scientific thinking and plant growing abilities! You all should be very proud of this project. Keep up the good work!
Susan (Dr. Bush)
Nice updates to the conclusions, team. I like that you included your stats this time!
If you were to add anything else, I would like to see you add WHY you found the results you did (with respect to white light, of course). Why is there a small p-value when considering the difference between Landsberg and phyA? Why were the phyB plants larger? Or less green? You've shared your statistics, but you can also interpret those stats - explain why.
Really nice job!
Susan (Dr. Bush)
Day 27 (11.14): We have been watering them and they are doing soooo well!!!!!
They look amazing!
Hi Team FISH,
A shame that the far-red light plants died, but I really enjoyed your conclusions from the white light plants. And I think the idea of measuring leaf color is still the smartest :)
Why do you think the phyB mutant plants grew the tallest? In your proposal, you said that phyB is involved in shade avoidance and is a mutation in a photoreceptor gene. Shade avoidance, as I think you know, is growing really tall to try to get out of the shade. You also told me that phyB is involved in de-etiolation, or when plants get enough light to turn green and grow normally. Does the phenotype of your mutant phyB plants make sense, given what phyB is normally doing?
In your proposal, you mentioned plants growing "to their full potential." Do you think that the Landsberg plants or the phyB mutants grew best in the white light? Why? What does "best" even mean??
Thanks for sharing your conclusions! I'd love to hear about the stats if you do them. Great job!
Susan (Prof. Bush)
Excellent! Just what I wanted to hear. Let me know if you have questions about interpreting your stats, etc. Good luck!
Susan (Dr. Bush)
Good afternoon Dr. Bush!!
Day 22 (11.09): We had watered all the plants! We will do both anova and t tests!
-FISH
Hi FISH -
I love what you did with your line graphs! That shows a really nice trend. Are these averages that are plotted?
I think it's cool that you can see that phyB mutants are taller and less green throughout most of their development. Is that what you predicted? Why would the phyB mutants have less chlorophyll, do you suppose?
Last question - are you planning to do any statistics on your data? It would be possible to do t-tests or anovas on each day's data to find out whether the phyB plants are different from Landsberg.
Great work, team! I'll look forward to reading some more of your data analysis and conclusions!
Susan (Dr. Bush)
Good evening!!
Day 21 (11.08): We are no longer gathering data :(( but we are still trying to keep the plants alive, and all of them are still thriving!! What we were trying to let you know that we had finished our final data along with line and bar graphs!!
Thank you,
FISH (Filip, Itzel, Safa, Heba)
Hi team,
Such excitement! Your plants are looking incredibly different at this point, aren't they!
I think it's interesting that the phyB mutants are so tall, but you think they have fewer leaves, huh? It makes sense to me that if they only have so much energy, they have to choose: do we make stems or leaves? Seems like phyB chose stems, and phyA chose leaves.
Now about your mutations: phyA-201 is a SNP mutation that causes a change from a glutamine to a STOP codon - likely a C->T change. If there's an early stop codon (it truncates about 200 amino acids early), then the phyA protein won't be able to completely do its job correctly (or at all). The phyA protein is a total of 1122 amino acids, and the mutation is at amino acid 980.
The phyB-5 mutant is also a SNP mutation of G->A that changes a tryptophan amino acid (TGG) to a STOP codon (TAG or TGA). This mutation occurs at amino acid 522, out of 1172 amino acids.
I got this information off the arabidopsis.org website:
https://www.arabidopsis.org/servlets/TairObject?id=115308&type=polyallele and
https://www.arabidopsis.org/servlets/TairObject?id=115300&type=polyallele
Hope this helps, guys. Let me know how your data analysis and conclusions are going! I'm happy to give you some input :)
Keep up the good work,
Susan (Dr. Bush)
Happy Monday!!
How was the extra hour of sleep?
Day 17 (11.04): Mrs. Beardsley watered all the plants before we had come in, found a new independent variable (flowers), far red in white lights for about five minutes (assuming they are dead anyway) but anyway added 400 mL of water.
Day 19 (11.06): Photographed all plants, white had all data recorded, along averages which had been added for all the other days that are found in the most recent data charts, there will be no more data taken until the end of the project but they still will be watered!
PS: I would recommend looking at the Day 19 photos in Phy B-5, because they are doing so well, height wise but leave wise not as much!
Hello there!
Dr. Bush, we were wondering if you know the exact characteristics of our mutants, phyA-201 and phyB-5. We have tried looking everywhere for it but cannot find it. We know predicted results as well as the fact that they are photoreceptor genes. However, we do not know what the mutants lack/ have different than the wild type photoreceptor gene.
We were wondering if you could help us on this issue.
Thank you!
