|If we use the blue light it will help the radish plant grow the most.
|Our hypothesis is If we use the blue light it will help the radish plant grow the most. Based on our experiment, the data shows that our hypothesis was incorrect.
|1. In all 4 Seed trays, use a shovel to put soil in each of the sections, so the soil is filled a little more then half way. 2. Then with your finger, or using a seed stick, make a small hole in each section in all of the seed trays that a seed can fit into. Make a hole in the middle of the...
|The purpose of the experiment was to find out if blue light helped the radish plants grow more than the other lights, pink, red, and sunlight. Since sunlight is important to plant growth, we wanted to experiment with different colored lights to see if different colored lights affect plant growth....

|Solid communication, and good thinking went into the conclusion, including an impressive discussion of the potential sources of error. Nice work! -- Jennifer Hartley, Liaison
Since your blue light plants were similar in height to the sunlight plants, I think you have the right idea that the other lights were trying to get more light by growing taller. Plants with access to less light will grow longer in an attempt to reach the light source. While I have not seen this with color, only amount of light, it would be a reasonable assumption. Perhaps instead of height being a "good" measurement of growth, you could think about these data as relational to "normal" conditions aka sunlight. Your sunlight plants measured 8.47, with blue 8.99, pink 9.73, and red 11.52 (inches? centimeters?). Thinking about sunlight as the control, how would you interpret these data?
Do you think that even though the blue light had the lowest average, it might have been because the plants under the other lights were trying to reach more light? Or the plants under red light actually had the best growth because we were measuring height?
I filled out the blue boxes. Anyone can change them if they feel the need to. I hope the information is good!
For the red light, our average was 11.52 cm. Pink light: 10.69 cm, Blue light: 9.16 cm, Sunlight: 10.58 cm
What were your averages?? I would love to see your data and hear your conclusions! Don't forget to fill out the project information above!
Today we measured the plants height and watered them. After we found the average of the plants. So for the blue light plant, we took the height from today, (the last day to measure the height) heights data, and found the average!
Result sections are my favorite! That's where you showcase all of the amazing data you collected. Graphs are a wonderful way to visualize your data. I would suggest a table that has all of your raw data (each measurement), then use a graph to show the average height every day. I don't know how much Mr. Kessler has talked to you about graphing so if he would rather you do tables then please follow his lead!
We're glad to hear you're back! Today is our last day of data collection. Tomorrow we will be focusing on the results section of the writeup. What should we include in our result section?
I'm back! Seeing all your progress has put a huge smile on my face. Don't forget to fill out the information about your project above!
That's good. Plants love water, but there's such a thing as too much of a good thing!
I've never heard of a plant shrinking, but maybe you've discovered something new. ;). How much did the plants 'shrink'? If it wasn't very much, it could have simply been a difference in the way you measured one day versus the next.
Your mentor should be done travelling after this week. I'm sure she'll be happy to hear about the progress you've made!
Again today we measured the height of all of the plants. But we did not water them because they were already pretty good from yesterday.
The lights have been on for 3 days now.
We oberved are plants today and some of them got shorter. How is that possible. We have recording data for all 4 plants, control, blue, pink, and red.
We measure the height of the plants and one day one, we missed measuring the control plant. I know it is okay but I thought I should say it!
That works! "What we can get our hands on to use." is a big consideration for real scientists too.
Just one suggestion: you might talk to Team 11 about plant height. Their radishes are growing some really long stems, but it isn't because they're healthy right now. Height doesn't always mean a plant is healthy; sometimes a tall plant is actually an unhappy plant that is putting on a lot of stem length because it's trying to reach the light or something else it needs to survive.
It might be worthwhile to think about other things you can measure about the plants. Otherwise, it sounds like you're doing a great job! (Don't forget to complete the fields up top!)
Now we are changing the violet (suposed to be outside light) with pink light because we have that light.
We have been watering the plants 4-5ml per seed. We have to change the violet light to white, since we don't have violet light. I belive then we will have blue, red, white, and one outside. Lotem is measuring the height of each of the plants and recording the information in a table. In our notebooks we would right down the quantitive data from the plants.
Hey Team 10! Jennifer is travelling this week, so I'll be checking in with you until she gets back.
How are things going? Did you start your seeds under the lights, or did you sprout them first and put them under the lights this week?
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!
Growth already, how cool! Any trends popping out on how the colors are impacting the growth?
We used radish seeds. Our seeds have already germinated. Most of the seeds have already grown roots and some have very long roots while other seeds have shorter ones. Most of the seeds have already grown very long stems and have leaves. Some have longer stems than others. Some have around 2-3 leaves and others have 4-5 leaves.
Also we are testing 4 different colored lights. Blue, Red, Violet, and control group White. There will be 12 seeds per each colored light, and we are watering each seed 5 ml per day.
Like Lotem said, the colored lights will be on from 7:30-8:00. That is what Mr. Kessler said. Every day we are recording the height of all the plants, and finding the average of the plants. Average of the 12 plants per each color.
So average of Blue, Red, Violet< and White.
