Info
| Explore | We know plants like sunlight and water. We also know that plants need good soil to grow good. From our research in class, we know that photosynthesis is when plants turn sunlight into energy. One question that interests us is how plants get stepped on and not die. |
|---|---|
| Research Question | What kind of liquid substance does a pearl millet seed thrive best in? |
| Predictions | I think that the seed will thrive best in the tea because it is more than just water. But i think the seed that will have the most flause is the coffee, and I think that the plain water and dye will grow almost the same because it is just water mixed with dye and then it is just plain water. |
| Experimental Design | 1. We will label the cup according to the liquid that is watering the plant 2. We will fill the cup up to the line 3. push the seed in 1/2 an inch deep 4. Then we will water it and see when it sprouts. |
| Conclusion | Our conclusion is that watering the plants with coffee was the best. These plants grew the strongest and grew the fastest as well. Pickle juice was the one who did the worst, all the plants molded and only a few of them actually sprouted. But even then they didn’t grow very tall. And water... |

Hey we wrapped up our project and we are working on sending you data graphs!!!
Hi Maris,
I'm looking forward to seeing those graphs!
Thank you,
Ruby
Why did water #2 mold and no other water plants?
Why did dye #4 and dye #9 sprout before every other plant?
Hi Maris,
I sincerely apologize for not responding to these posts. Were you all able to answer these questions in class?
Ruby
Why did tea #6 not grow after day 15 when the rest did?
Pickle Juice Plant Questions-
How come half of the pickle juice plants sprouted and the other half mold?
How did the pickle juice sprout even though it was covered in mold?
Tea Plant Questions-
Why did tea #6 not grow after day 15 when the rest did?
How come half of the pickle juice plants sprouted and the other half mold?
How did the pickle juice sprout even though it was covered in mold?
Why did the Coffee Plants take less days to sprout than Water Plants?
Why were some Coffee Plants stronger than others?
How are Coffee Plants better in our charts than water?
Why aren't people using Coffee to water their plants rather than water?
Hi, good morning
Good morning! Today we learned about phototropism, tropism, geotropism, and thigmotropisms. Our plants reacted to phototropism when they because they grow up towards the light.
Hi Ava,
That's interesting that plants have these abilities to sense and respond to certain aspects of the environment! Do you all have a graph or table of your final results? I'm assuming your experiment is finished and you have given up on any plants that did not sprout? Or, are you measuring plant growth?
Ruby
No, we are still collecting data everyday. Most of our plants have sprouted actually except for a few pickle juices.
Our plants are growing up so I think that is a responce to Geotropism. The stem is growing up and the roots are not trying to grow out of the ground!
Good morning Matea,
I think you might be right that the plant is exhibiting geotropism (negative geotropism for the roots!). There are multiple guiding forces for these plants :)
Happy Thursday!
Ruby
Today we learned about thigmotropism. Though we learned about this none of our plants are in the state of thigmotropism.
Today pickle juice #10 sprouted
Only one new pickle juice sprouted, #5.
nothing too new today
we watered our plants
Hi Bad Bees,
You all have some interesting data! It looks like you have mold in multiple treatments, but it is most common in pickle juice. Why do you all suppose that is?
So, which treatment(s) seem to be doing the best so far, and which one(s) the worst (in terms of how long they took to sprout)... water, tea, coffee, pickle juice, dye?
Great work. I look forward to seeing how each group fairs on your health chart.
Ruby
Water and coffee are the healthiest. Pickle juice is moldy and not growing so well so that is probably the worst.
I think coffee is doing because the plants are about half a centimeter above the rest of the plants. I think the worst one is pickle juice. This is because only two have sprouted and the rest have mold.
Pickle Juice I think is defintly the worst so far, only two have sprouted and their all moldy. I think the reason is because all of our substances are mainly water mixed with powder or tea bags and the pickle juice is half and half so... I think the ones that are doing the best are water and coffee. They both are thriving and strong. Coffee- 4/10 sprouted by day 4, then they all sprouted by day 5. Also the health chart has mainly C's and D's as well as water. Water- 2/10 sprouted by day 4, then 7 more sprouted on day 5, and today(day 6) all of them have sprouted.
This is our chart that we go by to collect data for qualitative. Also how we are measuring strenght.
Hi Bad Bees,
I love how diligent you were to make it clear how you classified health. This is great!
Ruby
We split up the different treatments
Qulitiative:
Coffee: Maris
Dye: Ava
Tea: Metea
Pickle Juice: Metea
Water: Ava
Qunitative:
Water: Maris
Coffee: Maris
Dye: Ava
Tea: Metea
Pickle Juice: Matea
Love that teamwork!
We planted two seeds in each cup. Both of the seeds have sprouted for all the plants other than tea four. This is an update on one of the plants.
This tea three is the best one that has sprouted over the batch of tea plants. All of the tea have sprouted.
The rest of my pickle juice plants have mold. Like this one.
This is my one pickle juice that sprouted. It is very small, but healthy.
Coffee 6 and 2 are the best coffees, and water 3 is the best water.
Water 2 is molding I don't know how or why but it is.
Dye 4 is the tallest sprout and dye 1 is the smallest. Today is day 5 of planting.
The substances we are using are pickle juice mixed with water, dye, tea, water, coffee. This is from Maris, her laptop died.
We re-planted on Friday! We are collecting data today.
Hi, only some of our plants sprouted over the weekend. Coffee and tea, also water and dye sprouted. All of those plants are very small, but healthy. All pickle juice started to mold, even though we put water in the pickle juice. Some of the coffee also started to mold, this mold is green! We will water the plants tomorrow, and see if the plants grew more.- Follow up on what Ava said.
We are going to restart we relized that we didn't have a control and that the salt and pickle juice wasn't working. So we are now only doing water, tea, coffee, and dye-water.
Hi Bad Bees!
Oh okay. Well, mistakes and the unexpected are all part of doing science, just as they are part of life in general! It's okay when things like what happened with pickle juice happen and it's not necessarily a reason not to include it in your experiment! You are doing this experiment to learn about what happens in each situation/treatment, right? So, I think that mold caused by pickle juice is a very interesting finding!! I certainly learned something. Great job!
So, how are you all measuring strength?
Ruby
We are still doing pickle juice but we are putting water in it instead of just flat out pickle juice.
All the pickle Juice ones have mold everywhere but we ran out of class time today so we'll have to send them to you tomorrow! Also we are collecting data by what day they sprouted and how strong the are.
Tea 8 just sprouted today so it is almost so small that you cant see
Coffee 7 has mold but it is strong and is still growing
Yea so we sent you pictures of all the ones that have sprouted.
1. dye sprouted- 2 days to germinate
4. Coffees- 2 days to germinate
2. Teas- 1 day to germinate
Good morning Bad Bees!
I'm sorry for the delay in responding. I've been out of town since Thursday.
Thank you for the pictures! So, is this all of your treatments (dye, 4 types of coffee, and 2 types of tea)? Do you all have a control (just water without anything else)? What about pickle juice and the other treatment you all discussed earlier? Just curious.
I'd love to hear how things are going this week!
Ruby
we will show you pictures tommorow!!!
Thank you.
Good morning! We are starting our project today.
Hi Ava!
I'm glad that you all are getting things going. I can't wait to see some pictures of your experiment.
Good luck!
Ruby
Good morning, these are the things we are that we are affically watering the plants with coffee, tea, pickle juice, water with dye, handsanatizer, and salt with water.
no, we are not using handsanitizer anymore and have 10 plants for each substance
Hi Maris,
Okay. Thank you for the update. Wow! You all are including a lot of plants in your study. Great job!!
I saw that you all have posted your predictions and study design. Nice work!
Ruby
For our experiment we are going to use different types of water. Like sugar water, dye in water, and other substances. To see if it affects the germination rate of the mustard seed.
and tea
Hi Bad Bees,
I saw that you all got to do some research to learn about germination and photosynthesis. I hope you have everything you need to create and carry out your experiment!
So, are you all really going to test the effects of all of these liquid treatments on seed germination? That is a lot of tests! Before you do these tests, it is always good to have some prediction about what you expect to happen. You all are the scientists and I'd love to see you tell me what you expect to happen for each of these treatments. So for example, how do you predict that coffee, dye, sugar, oil, and pickle juice will affect germination compared to plain water? Do you think that sugar will make germination occur at a faster rate, or slower? What about pickle juice? When answering these questions, you want to make an educated guess that is based on some knowledge. So, for example for pickle juice (which is vinegar), what kind of chemical is vinegar? Do mustard seeds require vinegar to germinate? Could vinegar interfere with the seed's ability to get the things it needs to germinate? Thinking about questions like this can help you create a prediction about what each treatment you listed will affect seed germination. I'm excited for you all to get started on this experiment!

these are the subsances we are mixing with water
I think we should put different types of seeds into different cups near the edge and give them the same amount of sunlight and water and see why it takes longer for different plants to grow
Today we research about photosymthisis, Respiration, and Germination.
We are going to research about photosynthesis. This is my idea,
if we plant a seed, we should plant it in a clear cup and mark where the seed is then see how it changes and grows bigger.
Hi Matea,
That seems like a good idea to plant seeds in a clear cup so that you can watch how the seed changes as it grows. I've never done that. You'll probably have to plant the seed right near the edge to make sure that you are able to watch it as it germinates.
So, what type of experiment are you all going to do to help better understand photosynthesis? Do you all have a good understanding of what photosynthesis is, and what a plant needs to do it?
Ruby
Today I learned that there is a difference between growing plants in ground-level gardens and raised gardens and that chives and mustard seed thrive best between 55-70 degrees and what the difference is between dicot, and monocot. Also what germination rate means. Have a good day!!!:)
Maris and Ava,
That is interesting that temperatures vary for some species, but seem to have a more narrow range that they like for other temperatures. I wonder why that is.
Glad to hear that you are learning so much! I hope that you all are able to spot monocots and dicots in your neighborhoods, now. You can teach your family ;)
Ruby
Today I learned that radishes best thrive in the 60 degree fahrenheit range.
Hi Matea,
Oh well I guess that makes sense given that they grown underground! Very cool. Thank you for sharing.
Ruby
Good morning for the question on how plants communicate I think that it is the chemical. I don't know how exactly that would work but I can research that we are quite busy today in class but on my off time maybe, I do have a soccer game today but hopefully I'll be able to fit it in tomorrow. During the Osmosis experiment we put egg in different liquids and saw and recorded how the egg changed then we graphed our data. We first put the egg in viniger for 1 night, then we put it into corn syrup, then water. It was really cool!!!
Hi Maris,
Yes! They can communicate by use of chemicals. I'm so glad to hear that you all enjoyed the egg experiment. I'll have to try that one myself!
Ruby
During research, I learned about Leek plants. They thrive in temperatures around 60. They like sunny environments.
Hi good morning! What part of the plant absorbs the sunlight?
Hello Ava,
It really depends on the species, but one structure in plants is generally the most absorptive. It has a lot of surface area? Any guesses?
Ruby
Morning!!!! Sorry I have one more question, how do plants communicate with each other? Also we just went through a science lab looking at how osmosis works using an egg!!!
-Maris
Hi Maris,
Way cool! Glad you all got to experiment with osmosis. What was involved in the experiment?
Were you able to find any answers about how plants communicate? To answer this question, think of some of the ways that animals communicate: visual cues (dancing), sounds (alarm calls, singing), chemical (marking territories like dogs, signaling danger or getting rid of predators like skunks and ants and jellyfish), and touch. Which of those do you think plants should be able to do well?
I have one more question! How do plants grow back every year even if you don't plant them again?
Hi Ava,
Hmm. I'm not sure exactly what you are asking, but I'll try. So, annual plants (plants that only live for one year or season) will flower, be pollinated, and make seed that are dispersed on the ground. The following season even though that "parent plant is dead", the seeds from it will germinate and a new generation of plants goes through the same annual cycle.
Hope that helps!
I've learned that grass can't be ruined just by stepping on it because it is flexible and can bend. But sports being played on it such as soccer and football can compact the grass, which reduces drainage. And if a field doesn't have a good drainage system then the field could flood which ruins the grass.
Very interesting, Maris.
Thank you for sharing!
Hi all! Sorry to interrupt; I just wanted to quickly introduce myself. My name is Jennifer Hartley, and I am the 'liaison' for your class this session. My job is to support your teacher and mentors.
I work for the Botanical Society of America, and I'm a graduate student with Miami University in Oxford, Ohio. My research there is on soil health and macroinvertebrate communities (which just means I look under rocks to see what crickets, worms, and other critters I can find there). I'm also a former middle and high school teacher, so I really enjoy working with PlantingScience.
You may see messages from me from time to time, especially if your mentor has to take a few days to do some work. Great job so far, and I'm looking forward to seeing what you all come up with!
Okay!!! Thank you so much!!!
Hi Jennifer,
It's nice to meet you. We're happy to have you here. Your research sounds really fun and interesting. I hope it is all going well.
Feel free to participate as much as you want!
Ruby
Something I didn't know about plants is that some plants can react to sound. I also didn't know plants can recognize their siblings! One more thing I didn't know is that there are over 300,000 types of plants!
Hi Ava,
Oh, wow! You all are learning some really neat things. I'm jealous! We did not do that when I was your age. I'll have to read more about how plants react to sound. I didn't know about that ;)
Ruby
I also have a fear of bees. I think our team name should be "Bad Bees". I have a few questions too, How does grass get stepped on but does not die? and How do plants drink water?
-Maris
Cool name!
The sort of short answers to your questions are 1) plants have very different organ systems than we do, so damage to some areas of a plant are not always detrimental to another part of the plant. 2) Plant cells are able to take up water directly into the plant through the plants' outer layer or cells, or skin (a process called osmosis), usually in the roots (but it can happen elsewhere). Actually, amphibians bring water into their body in a similar way and don't drink water like we do. Due to our different lifestyles, our skin doesn't allow us to take up as much water through osmosis. These are good questions and you could try to find more information about them yourselves! Reading more about these processes (such as osmosis and plant vascular systems) would be great ways to try and figure out what hypotheses you might want to test as your project!
Hi my name is Matea. I love sports, I like track and cross country. I have one sister, and a lot of cousins. I love art, and I craft a lot. I also like math.
Hi Matea,
You must enjoy running more than me... I'm impressed by cross country! Math might be a useful skill for your project so the other Bad Bees are fortunate to have you I look forward to learning with you all as you develop your project!
Ruby
Hi I'm Ava. I have one brother. I love cheerleading. I have two dogs and a cat. I also have two bunnies. My favorite food is pizza. I don't know much about plants.
Hi Ava,
Brothers are the best. I have 2! Sounds like you also have a lot of wonderful pets, and must have some good balance being a cheerleader. Just like anything, you can learn about plants pretty quickly with a little effort. I look forward to working with you!
Ruby
Sounds good
Ok
Okay for the name.
I also have a fuzzy cactus.
Hi my name is Maris. I do a lot of sports such as basketball, soccer, track, and softball. I also do a lot of other sports with my older brother and younger sister, and I have 2 dogs. I spend most of my time playing on sports teams and playing with my little cousins. I also like to hangout with my friends. My favorite sport out of them all is basketball, then soccer.
Hi Maris!
My name is Ruby. I love playing sports, too. My favorite is softball, but basketball is a close second. I'm glad that you have the opportunity to be so active with friends and family. I hope you love your science project as much as basketball I'm looking forward to hearing about the science project you develop in the coming weeks!
Thanks,
Ruby
