Info

Explore We know that plants need photosynthesis in order to grow.
Research Question We want to test whether or not colored light will affect the growth rate of a plant.
Predictions The rate of germination will increase under Red light
Experimental Design Our plan is to take seeds that germinate fast and put it under different colors of light and measure if the rate of germination changes between them all. 1. Put seeds in a wet paper towel and put them in different colors of light. 2. Measure the rate of growth between the seeds. 3. After a...
Conclusion The claim that we can make is that under different colors of light the rate of germination will increase. After 2 weeks we can conclude that the color of light does effect the rate of germination by seeing that the plants have sprouted and the colors of the seeds themselves have changed. And...

Updates

Get to know your team’s scientist mentor, who will encourage and guide you through the scientific process of discovery. The more you share your ideas and research info, the more your mentor can help. You may also hear from a scientist mentor liaison who will be helping all the teams in your class.

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. You have until Thursday, December 09, 2021, to post ALL of your updates, comments, and goodbyes. 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 Trevor and Zaire,

Thank you for your kind words.  I have enjoyed working with your Team.  Nice job so far.  Your observation that seeds under red LED light exhibited greater germination rates in comparison with the other colors of LED lights is cool.  Put that together with your observation that seeds germinated inside a bag.  Your conclusion that photosynthesis can grow anywhere is fantastic.  Now you know something about photosynthesis and seed germination that you are learning on your own.  If you think about plants that are grown inside greenhouses with glass, plastic, plexiglass or other transparent or semi-transparent roofs, what can you say about photosynthesis going on inside a greenhouse? 

Keep up the great work and keep me posted.

Plants are cool,

Donna Hazelwood, Ph.D.

That the red LED light germinated more seeds then the other LED lights and Photosynthesis can occur anywhere even if it is inside a bag. We are going to keep on going with our experiment for a couple more days to see what will happen and thank you very much for being our mentor.

Good morning! First and forest thank you for the responses and helping us breakdown our project. My group and I truly appreciate it. I personally like how our project is growing in a classroom and not in its natural environment with a different source of light.

First and foremost thank you for your service and guidence during our project. Your responses really helped us understand our project more.

Hi Team and Mrs. Sweeney,

Nice job, team. I enjoyed seeing the photos of your results.  High five.   Fun questions for you.  What did you learn from doing this project?  What did you enjoy the most? If you were going to do a follow-up study, what would you like to do?  Scientists like to design new experiments based on information from the experiment that they just finished.  This is a fun part of doing science.

Enjoy the satisfaction of a job done well.

Plants are cool,

Donna Hazelwood, Ph.D.

    We learned that different colors of light affect the rate of germination, I enjoyed watching my plants grow over time, I would limit the amount of colors to two different kinds of colors and a control. Our experiment is ongoing we wanted to see if the different colors changes the colors of the bell peppers when they grow, and thanks for always answering our questions when we asked and intrigue our curiosity.

Hi Team,

thank you for your photos and updates.  Good thinking that bubbles indicate that photosynthesis.  What can you tell me about the bubbles?  What is in the bubbles?  Do you think that whatever material is inside the bubbles dissolves easily in water? 

Good observation that the seeds grown under white light are showing signs of germination.  Carefully observe those, and any other seeds that are germinating.  Did the seed get larger in size or swel  before the first structure emerged? What color is the first structure that you observed emerging from the seed?  Is the direction of growth of the structure up (away from gravity)  or down (toward gravity.  Keep watching and make the same observations for any additional structures that emerge from the seed.  Seeds are amazing and seed germination is even more amazing.  

Changing the paper towels with fungus growing on them is a great thing to do.  When fungus grows on the paper towels, the paper towels are said to be contaminated.  Something to think about; the fungus can come from touch, perhaps hands, so washing hands, and anything that comes into contact with the seeds, is a good thing.  The fungus can also come from. the air.  Many fungi, (plural of fungus) produce tiny structures that are called spores and are easily carried by air currents and germinate if they land on a suitable surface.  New word for you.  a surface, such as a moist paper towel, would be called a suitable substrate  (one that can support the growth of the fungus).  Have you seen fungus growing on bread, usually older bread?  If you did what color was it? 

Have fun with your project and keep me posted.

Plants are cool,

we have had to change the paper towels in our experiment because there was a fungus forming

For our seeds there hasn't been any change for the past four days. However we observed that photosynthesis has taken place. Also, for our controlled variable which was one of our seeds under a white light, showed signs of germination.

HI Team

 

thank you for your update.  Your project will be interesting to follow.  May I suggest a couple of modifications to give your project what scientists call controls?  A control gives your project something to compare red, blue and green light against.  A negative control would be darkness and a positive control would be white light, that is no filters.  What would you expect for seeds grown in darkness?  What would you expect for seeds grown under white light.   Then you can compare rate of growth for your variables, red., blue and green light against the controls and against each other. This makes your experiment more robust.  A robust experiment takes your experiment to the next level. 

have fun and keep me posted.

Plants are cool, 

Donna Hazelwood, Ph.D.
