Info
| Explore | Vegetables usually require six to eight hours of sunlight a day. It also promotes vitamin D, which is a critical nutrient. Blue light helps plants with chlorophyll production. Red light helps with photosynthesis and plant growth. |
|---|---|
| Research Question | What is the best light to help with germination and plant growth? |
| Predictions | I believe that natural sunlight is always the best for the plant as that is how they began to thrive on land. But also I think once the seed germinates the red light will promote more growth. |
| Experimental Design | We will test three different plants with three seeds of each. Using an seed starter (small pot) and soil we will measure in inches and days. We will be testing sunlight, red and blue light. Each will have an equal amount of light for 12 hours a day. The lightd have timers to turn off at dusk and... |
| Conclusion | Overall the red light was great for germinating and grow first and long, but the sunlight helped the stems stand up strong, the blue was the in-between. |
| About this Project |
The students that did this project went beyond just analyzing which plants germinated the quickest and grew the tallest during their experiment. They observed that maybe while red light caused the plants to germinate early and grow very tall, they were spindly. While natural light was the... |
Updates
Thank you to the planting science for all your help. Thank you Hannah Berry for being our mentor. This was our first year participating. We will be back again next year knowing more what to expect.
As this research project is now in the final stages of wrapping-up, we wish to thank everyone who participated in this inquiry; the students, mentors, teachers and others behind the scenes. We appreciate all of your efforts and contributions to this online learning community.
Scientific exploration is a process of discovery that can be fun! There are many unanswered questions about plants just waiting for new scientists to consider, investigate, and share.
After the end of the session, we will be updating the platform and archiving groups and projects, after which time new updates/posts will not be able to be added to projects or groups. Please come back and visit the PlantingScience Project Gallery anytime to view this project in the future. You can search the Gallery by keyword, team name, topic, or school name.
Good bye for now.
Warm regards,
The PlantingScience team
Just as a reminder, the end of this session will be 11/29/2019. It’s great to see that teams from your school are wrapping up. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
Hi Team,
How is your data analysis going? How are you planning on analyzing your data if you have not done so already?
Hi Team,
Wow you guys are fast! Could you give me a little more detail about what you saw in your experiment? How are you planning on analyzing and presenting your data?
We have now stopped collecting our data we are going to make the graph soon. And update the page to let you know our conclusion.
Hi Team!
Your plants look nice. Could you give me an update on how things are going?
Hi Team,
Your plants and data sheet look really nice! Are you already ending your experiment or continuing collecting data still?
We have also adjusted our light timers to correspond with the sunlight when it comes up and sets. We are creating the graph now to record our data.
Day 2: October 21st
Sunlight:
-
Radish- 1.2, 6.4, 6.5 = 9.7
-
Peas- 12.5, 6.2 = 15.6
-
Nasturtium- not germinated
Red Light:
-
Radish- 13, 11.5, 12, 5 = 37.75
-
Peas- 26.5, 23 = 38
-
Nasturtium- 15.5, 13 = 22
Blue Light:
-
Radish- 10.7, 8.9 = 15.15
-
Peas- 14.4, 15 = 21.9
-
Nasturtium- 2.6, 2.6 = 3.9
-
All of the seeds now germinated except the nasturtiums with the sunlight. Now overall the peas are the tallest in each of the light. Most of the plants were tallest in the red light. The blue and red light with the plant's soil looked healthy and still a little damp, but when we looked at the ones with the sunlight the soil was completely dried up.
-
These end measurements are the overall average.

Hi Team,
I am a little confused about the numbers you sent me. I think they may be averages? Do you guys have a table you are using to collect your information? This may be the best way to share your data day-to-day. Looks like your plants are off to a good start!
Day 1:
Sunlight: 3.2cm
-
Radish- 1.3,3.5,3=2.6cm
-
Peas-.6cm
-
Nasturtium-not germinated
Red Light: 5.15
-
Radish-5.1, 4, 4.5=4.5cm
-
Peas-.6,.7=0.65cm
-
Nasturtium- not germinated
Blue Light: 2.55
-
Radish-2.5, .5=1.5cm
-
Peas-.6, 1.5=1.05 cm
-
Nasturtium- not germinated
Hey Team!
Could you tell me a little about the photos you uploaded?
