Mask Wearing Plant Geeks

Project by group dmsgrayspring2021

Info

Explore We knew that plants needed water, sunlight, and space to grow! plants take in co2 plants do photosynthesis and cellular respiration.
Research Question How does the sugar in lemonade, lemon juice and sugared water instead of plain water affect how fast the pea seeds sprout and how long they grow?
Predictions If there is too much sugar in each of the liquids, then it will not grow as quickly, because plants grow on water, not sugar. Sugar is an unnatural input to help seeds sprout and grow, so it could make it die.
Experimental Design Independent Variable = type of liquid Dependent Variable = how fast it grows Variables to Control = type of seed, dampness of paper towel, type of liquid Materials: paper towel, petri dish, sugar snap peas(4 or two in each),lemon, toothpick, lemonade, water (20 drops for each),...
Conclusion Claim: My results are mostly inconclusive, but the bottled water grew on the last day.  Evidence:  On every day except for on the last day the seeds didn’t grow at all, but on the last day the bottled water grew 1.3 inches. This was a lot because the lemonade, lemon juice, and the sugar water...

    Day 5 is when a seed sprouted 

    Only one seed out of the five sprouted (in the bottled water).

    Robert Louis Hirsch
    said

    Ok, thanks!  Are you able to continue this experiment or is 6 days it?   I imagine that these data will continue changing if you give the pea seeds more time. 

    Christine
    said

    We had an option to, but since we didn't know that we could have possibly saved the seeds, we made our last observations and threw them away.

Explanation:

Claim: My results are mostly inconclusive, but the bottled water grew on the last day. 

Evidence:  On every day except for on the last day the seeds didn’t grow at all, but on the last day the bottled water grew 1.3 inches. This was a lot because the lemonade, lemon juice, and the sugar water didn’t sprout at all. Also over the weekend all the petri dishes and seeds grew mold.

Reasoning: This outcome was explained when I did a little research. I found out that it was the sugar that affected the growth of the seeds. When the liquid a seed is trying to use to grow has too much sugar then the sugar will suck up the liquid and make they seed die from “dehydration”. This result is pretty much what I had expected. I had expected for the bottled water to do the best because it had no sugar, but i didn’t think the other ones wouldn’t grow at all. I also never expected for them to get moldy at the last minute. It wasn’t really a fair test because we didn’t always add the same amount of liquid and we didn’t really measure the sugar so it wasn’t super fair.

    Hi Paige,

    Great observations!  I always say that experiments can never fail, they can just provide inconclusive data!  The only way that science fails is when scientists do not take their observation and improve their next experiment.  It sure seems to me that you all are well positioned to do this again differently, and probably get more consistant data.  Great job.

Some errors that I think were made during this investigation, are as follows!

We did not clean the pipet after we used it. We used the same pipet for all the seeds and we did not clean it before using it in another liquid!

So I think if we would have cleaned it or used different ones for each liquid it would have been better because the remains of one liquid could contaminate another!

The liquids we gave the seeds had too much sugar, and if a seed/plant gets too much sugar it will not grow! I think we should have done some research on how much sugar a seed/plant can handle and balanced it out! ( although that was the whole point of our investigation)

We used a lot of similar liquids, I think if we used liquids that were a bit more different from each other!, it would have given more individual results! 

I am not very confident in this investigation, because as you can see there is quite a few things, we could have done differently!

 

    Robert Louis Hirsch
    said

    Hi Yvette, I agree that it looks like there was too much sugar.  I agree with your great suggestion of looking at different concentrations of sugar for the next experiment, which can impact the seeds in addition to all of the infesting fungi that you all cultivated as well!

    They all molded :(

    Robert Louis Hirsch
    said

    I am really sorry to see that, but mold is something I know a little bit about!  Can you send me some better pictures of the moldy seeds so I can maybe tell you something interesting about it!  Also, what do you think you could have done differently in the early part of your experiment to kill/remove any external fungal spores that may be contaminating the outside of the seed coat?

    Christine
    said

    So we had to through the seeds away but we can try and zoom in on the picture for each dish if that would help.

    Robert Louis Hirsch
    said

    Hi Christine,

    It's all good, no worries.  I think if you would have soaked the seeds in a 10% bleach solution, that would have been enough to kill most of the infesting (i.e., on the outside) fungal spores that are naturally occurring on seeds.

    Ok, so the seeds are starting to germinate?  You are right that the picture is a little blurry.

    Thanks Christine!  Looking good.  Is the bottle water dryer than the lemon juice and the lemonade?  Keep up your observations!  

    Christine
    said

    I think so. None have sprouted yet, but hopes are still high! We started on Monday, not Thursday so ours will take longer to sprout.

    Robert Louis Hirsch
    said

    Ok, great.  You may have some germination occur over the weekend, so just do the best you can. 

Christine
said

Update: Mrs. Gray said we should add more liquid to the dishes so that's the little change to the investigation. 

    Christine
    said

    It's a little much, but now from 20 drops we are doing 40. I agree that it was quite dry so hopefully this will help they germinate and sprout.

    Robert Louis Hirsch
    said

    Ok, great!  As long as the water treatments are consistent across all the samples, you should still be good!

    Ok, looking good!  Be sure to record your observations at least once a day, because you may see a difference in the timing of germination in addition to the eventual growth.

    Christine
    said

    Will do! P.S. we changed the amount of drops for the liquids to 20 drops. When we did 10, it didn't seem like enough.

Robert Louis Hirsch
said

Great prediction!  What specific ingredients in the lemonade do you think are bad for the plant?  What type of lemonade are you using (natural is quite different than dry mixes)?

    Christine
    said

    Possibly the sugar in the lemonade. I am not sure what type, but when Mrs. Gray gets it, we will let you know. Most likely natural.

    Robert Louis Hirsch
    said

    A cool control for your sugar idea is to figure out how much sugar is in the lemonade and then just make a solution containing the same concentration of just sugar. Doing so should be pretty easy (probably you or one of your lab mates has sugar at home they can bring), and then you could compare the differences between sugar and powdered lemonade mix.  If you used real lemonade, that would be much more acidic since it is made by mixing real lemon juice (full of citric acid) and sugar. 

    Christine
    said

    I'm a little confused. Could you elaborate?

    Paige
    said

    So what you mean is that we should figure out how much sugar is in the lemonade and try to balance it?

    Robert Louis Hirsch
    said

    Hi Paige and Christine, I am so sorry for missing these comments when you posted them!  I was asking because depending on the type of lemonade, there could be multiple different chemicals impacting the seed germination.  Natural lemonade will have lots of sugar in addition to citric acid from the lemons, whereas lemonade from a powdered mix will have just sugar.  However, it looks like you worked on this issue without my input, so great job!

I'm not sure if anyone else posted these, but here are our thoughts on what questions we might ask: Can sunlight help a plant sprout?  How much water does it take for a plant to sprout? What out of the box things can help a plant sprout? 

    Robert Louis Hirsch
    said

    Hi Christine, great questions!  Here are some questions that may help flush out your thoughts more: 

    1) What plants (seeds) are you working with?  Some plant seeds require specific wavelengths of light to germinate!

    2) Water amount is a good variable to measure!  I am interested in learning how you will set this up.

    3) What are some items that you think may have an impact?  Again, it depends a lot on the type of plants you are working with. 

    4) How about temperature?  Do you have any way to incubate your seeds in different temperatures (this does not have to be super well controlled, but somewhere cold, room temperature, and warm)?

    Christine
    said

    1) We have options of using Alfalfa, Buckwheat, Pea, Corn, Fava Bean, and Pearl Millet.

    2) We were thinking about doing something that's related to the water one! Seeing how quickly a plant could grow with a certain amount of water or something.

    3) Well, one of our teammates, Paige, talked about using lemonade or some other liquid in replacement of water. Seeing how it would turn out?

    4) Mrs. Gray said that we don't really have a way to change temperature, as in heating. It could be possible putting it in the fridge, but were not sure. 

    We will keep you updated.

Hi Everyone!  

My name is Lou Hirsch, and I am faculty member in the Department of Plant Pathology at the University of Kentucky (I study plant diseases and the microbes that make plant sick, so I am like a plant doctor).  I teach several classes to college students and graduate students (future scientists earning their Masters or Ph.D.s, and am the director of two different degree programs (so like the equivalent of your school's Principle). In my free time I play on a (very bad) adult kickball team, and I am also a scuba instructor when the weather is nicer.  I am really looking forward to helping you all out with your project, so let me know if you have any questions!

Hi, my name is Christine. In my free time I play piano, sing, play soccer and form time to time write stories. About 3 years ago, I moved to Michigan from Seattle, Washington. I look forward to working with all of you!

    Robert Louis Hirsch
    said

    Hi Christine, thank you for the introduction! My grandparents lived in Grays Harbor County (about two hours west of Seattle), and I spent most of my summers as a child in Washington.  Cold and rainy most of the time, but I loved spending time outside!  Great memories.  What are you favorite type of stories to write?

    Christine
    said

    Well I don't have a major preference but I do normally write horror stories. A few days ago, we had a English project and I wrote a story called Jangles. It's kind of about a killer jack and the box that kidnaps teenagers... I know it's not everyone's favorite genre, but it's mine!

Hi, My name is Yvette, in my free time I enjoy baking, spending time with my family and friends, and crafting. I look forward to learning more about plants with you!

    Robert Louis Hirsch
    said

    Hi Yvette!  What is your favorite food to bake?  Have you gotten into the sourdough craze that everyone seems to be doing now during the pandemic?  Also, what do you craft?  I have taken to cross stitching recently (mainly to make funny pieces that I give to my friends)

    Yvette
    said

    I really like baking cakes!

    I have not gotten into sourdough yet but my mom and I wanted to try it out!

    When I craft I usually make things like rings, necklaces, and bracelets.

    Cross stitching sounds fun!

Hi my name is Paige. In my free time I like to read fictional books, sketch, and play on my phone. I also play soccer and basketball. I am learning how to crochet and sew so that is fun. I am crocheting a blue blanket for my baby brother. I have 9 siblings (but luckily I don't share the same household with all of them). I am reading the Shadowhunters series and I really like it. I am really excited to learn with you!

    Robert Louis Hirsch
    said

    Hi Paige,

    Thank you for introducing yourself!  Nine siblings sounds just insane, I have no idea what that is like (I only have one younger brother).  I crocheted a bit when I was a kid because my grandma did and she showed me, but I wouldn't know how to start anymore.  Also, while I have never read the Shadowhunters series, my wife has, and she LOVED them!  What are you going to crochet next?

    Paige
    said

    I am going to try to crochet a pair of socks or maybe just a bigger blanket. Also I think it is really cool that your wife loved the shadowhunters series they are really great books.

    Robert Louis Hirsch
    said

    That's cool Paige!  Have you tried knit caps?  My wife bought a circular loom, and she can complete a hat in about 90 minutes if she uses thick yarn.
