|We know that the 5 important aspects of plant growth are sun, water, soil, nutrients, and carbon dioxide. Our experiment is testing sun and carbon dioxide.
|The question that we are testing is, do different environments affect plant growth?
|Our hypothesis is, If we plant our plants outside, then they will grow taller. We think this because it will have access to fresh air and nutrients.
|Procedure: Put soil in our plant trays Poke a holes in the soil (pencils will work) and put in the seeds (12 different sections per tray – 1 seed per section) Put the plants in their individual areas and make sure they all get the same amount of sunlight. Water them daily (use the moisture...
|The overall goal of our experiment was to find the best environment to grow a plant. We judged which location was best by which plants were tallest. As a result of our experiment, we found that radish seeds grow best outside with direct sunlight and average amounts of carbon dioxide. Our...

|A good conversation, and a solid conclusion in which they incorporated elements of the mentoring provided into their thinking about what they discovered. -- Jennifer Hartley, Mentor
Thanks for the feedback! Multiple of the plants in all the locations put out the spiky adult leaves, but we didn't want to judge it based on that because from the beginning, the size of the plants differed, because we germinated our plants.
Hi Dahlia (and team) -
You did a great job filling out the fields above. Nice job!
I also like your graph below. It's very clear and easy to read, and that's important for communicating data.
Did your radishes put out any additional leaves, did you notice? I'm just curious. The healthiest plants should have put out more than the two you saw initially when they first sprouted and were winding all over.
Hi Dahlia (and all) -- Try uploading the data to the Files section. Then I'll be able to see it.
Hm. Well, can you share your data with me? Your conclusion is where you tell the story of what you think happened during your experiment. I'd love to see how the three areas turned out.
This was our last day of measuring! Tomorrow we're going to start writing our conclusions. Do you have any advice on how to write our best possible conclusion?
Wow, they sure did!
Incidentally, are you measuring anything about the environment in each case? I'm wondering if you might want to at least check back to see how the temperature outside compares to the temperatures in the other locations you're using.
Another thing to consider is how many hours of light they're getting. Outdoors, the plants are probably getting around 11 hours of sunlight. You might ask Mr. Kessler how long during the day the lights are on in your classroom and see if it's different.
Sadly, no. This is what I meant by 'leggy' -- they haven't had enough light so they are growing all over the place trying to find some. ;). As a result, their stems are really weak.
But it's okay! You can start again if you want to, but you also might want to just keep going with these plants and focus on their leaves.
Those first leaves you see in the photo are their 'seed leaves', (also called 'cotyledons'). They're like baby teeth, in a way - smaller and thicker than the plant's normal leaves, and just there to help it get going until it finds enough light.
They will put out another, 'real' set of leaves once you have them in the light. You might consider tracking how long it takes each plant put out their real leaves? That would tell you something about how happy they are in each environment?
This is one of our seed trays. our plants have been growing really well and we're starting the experiment! Do you know of any ways we can stop them from bending as they grow?
Hey Team 11! Just checking in this morning. I heard from Mr. Kessler that you had a day off yesterday. I hope you were able to do something you enjoy. This time of year here in Missouri is when the leaves are turning colors and the air is turning cool in the mornings and evenings. Its nice.
Hopefully your germinated seeds are doing okay after the break, but if not, try not to be discouraged. That sort of thing happens often to scientists who study seeds, and fortunately, radishes sprout quickly
Hey teams! I gather things are going well in the classroom!
I just wanted to post a reminder to everyone that you can - and should - edit the blue fields at the top of your project pages. Click on 'Info' in the left-side menu and then look for 'Edit Project' on the right side of the Info page.
At the end of the session, I get to nominate groups with those fields completed to be considered for 'Star Project' status. If your project is selected as a Star Project, you'll receive prizes from PlantingScience!
There are questions posted with each of the fields to help guide you regarding what to write. Mr. Kessler and I are also happy to help explains, so let us know if you have any questions!
The germination went really well! The white roots have pushed through the paper towel to our plastic bag, and the shoots have broken out of the seeds and are thriving in the paper towel. We will plant them and begin our experiment tomorrow!
Hi all! How did the germination go?
It was a beautiful weekend here, much cooler and more fall-like than previous weeks have been. My soil critters seemed especially enthusiastic. One of my test site pavers looked like slugs had some kind of rave overnight. ;) I'll try to post a photo to show you.
Hope it was a nice weekend there too!
