The Light of Life

Project by group rhsnicefall2019


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...

Farewell and Best Wishes
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

Hi Team,

How is your data analysis going? How are you planning on analyzing your data if you have not done so already?

Hannah Berry
said

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 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!

Hi team!

I like your new experiment and looks like you guys have thought of a lot of components of the design. How long will your lights be on and will they be on a timer so they get some light over the weekend? What colors of light are you testing? Looks like you guys are doing sunlight and red but are there others too? Looking forward to your results!

Hi Team!

Thanks for providing more information about your experimental design. How long do you think your experiment will take to see results? I like the idea of using multiple types of seeds to test your hypothesis!

Hi team!

I noticed you have filled in info for your research question and predictions and are off to a good start. Could you describe your experimental design in a little more detail, please? What directions will you be testing? How many seeds per direction? How often will you be watering your seeds and what will you be planting them in? All of these things are important for experimental design and something I think about for my own experiments. I really like your research question!

Hi Hannah,

This is Ms Nice.  To give you a little background on the questions they were asking you, we started the Corn Competition activity.  Most of their corn grew very fast and then turned brown and wilted.  They were planted in the brown seed starter containers and kept by the windows in the classroom for most of them.  I had them take a question about that competition to help them introduce themselves to you.

Today we will be going through the Student Guide set up steps and each group will be trying to narrow questions about seed germination down to 1 testable question for their projects.  Our project is on the Wonder of seeds.

Hi, I'm Julian, I was wondering how the steam's of seeds breakthrough when the seed is hard? 

    Hannah Berry
    said

    Hi Julian,

    When you germinate seeds, a lot of things are happening so the seedling embryo can break through the seed coat and develop into a plant. One of the main things that happens is the uptake of water that activates some enzymes initiating plant growth. With all the water intake, the seed softens and allows the root to break through first, so the seed isn't actually hard anymore when you see the roots and stem.

What can of light, such as artificial or real sunlight, would be best for a plant that is just getting started. Like it started roots as well as have leaves just a few inches tall.

    Hannah Berry
    said

    Hi Maddie,

    Real sunlight is always best for plants since it is what was available when plants evolved. As for supplemental light, it really depends on the species of plants. The color green you are typically seeing is the wavelength of light reflected from the plants and is therefore not used by the plant for photosynthesis. In these plants, red light is most absorbed and used for energy. So what colors of light do you think a purple plant reflects and absorbs for photosynthesis?
