THE COUNCIL OF JIMOTHY

Project by group bcsboylefall2020

Info

Explore That plants form photosynthesis that produces oxygen for man kind. That there are many plants that I thought were from Maine but ended up to be an invasive plant. How do they make their own food?
Research Question we want to see which light will help the plant and which will kill the plant. well we thought of how the sun has a lot of different colors. so we were going to see which works the best. they fit because the topic is about the lights so we were going to break down the colors of the sun into there ...
Predictions What are the possible outcomes of our study given the variables we are working with? What is our explanation for why and how we think this will happen?
Experimental Design We will have four cardboard boxes, each with a volume of 216 cubic centimeters. Each will have ten cups, which will be five nasturtium seeds and five corn seeds. each box will be equipped with a two lights, and each box will have a different light. We will use blue lights, red lights, fluorescent...
Conclusion What claim can we make from our experiment? What are possible explanations for our results? How do the data we collected and our reasoning with scientific ideas support our claim? What future experiments could be done to expand on the results of this experiment?

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

Looks like you are in the final stages of your projects.

It’s great to see that teams from your school are wrapping up and posting conclusions. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.

Hi Team,

Thank you for sharing your claims and the evidence you are using to support those claims! These are thought out and expressed clearly!

Thanks also for sharing the images of your drawings, tables, and worksheets. This helps me see what you are seeing.

I'm looking forward to hearing about what you discuss about the project as a whole, and to see the line graphs that you make. I think your plan for a line graph and for your x and y axes is great. I think it will show the data very clearly.

so in class we were doing CER on are the plants that we did and I hade blue light so my claim was that blue light was not very fast at growing the plants evedance was only one plant sprouted the entiare week was the ble light was slow to sprowt

For data collecting, we will be gathering all the data into a table, and most likely graphing it, too. For graphing we have been thinking from the start to do a line graph. for the data itself we  would have height off the y-axis with the day/germination time on the x-axis. We will most likely be color-coding the different pieces of data as well.

Today in class we did CER. My claim is that the red light plants did not germinate. My evidence is that there was no growth and that there were no seeds. My reasoning states that because there were no seeds and no growth, my plants did not grow. Next week we will make claims, evidences, and reasonings on the project itself.

Hi Team,

Wow! Brody, that would certainly explain why nothing sprouted from the pots under red light!

Will you all be gathering your observations into a table? If you do, it would be great to see all of those height measurements when you've finished.

Great updates!

so my final langth of my plnt was 12 1/2 cm tall

Mt plants grow phenomenally. One of them grew 16 centimeters tall.

Hello. Today we cleaned up our plants and found out why the red plants refused to grow. When we were planting we completely forgot to seed them, while adding about 5-6 seeds in each LED cup. This explains why the LED plants grew so well, and none of the red lights grew. almost all of us have decided to keep growing some of the plants, and Gabe had given me some of his to grow. Thank you for all the advice you have given us thus far when planting.

so far the only plant that has grown under the green light is BD5 that is 10cm. tall

I've got my plants in a window facing south, but its cold here and fall.  The natural light isn't as long or warm, so only one plant has sprouted but it's about 1 cm tall and I uploaded a picture.

Hi Team,

Those are great ideas! I think you're right about both the angle of the light as well as how much light is being given off by the bulbs. The LED lights are likely giving off both red and blue light, as well as light from across the visible light spectrum. The plants under the LED lights will be able to make use of most of this light. Those that are growing under only red or only blue lights, will have just those wavelengths of light to use!

The angle is also important. Since LED lights typically shine light in a particular direction and regular bulbs will shine light in all directions, it's good to make sure that the regular red and blue bulbs are placed where the plant will receive most of the light from them.

Good observations, and great brainstorming!

Brody

Hello. I have discovered what we think is the main reason for the LED growing the fastest. when setting up the experiment we ended up having the light from the red and blue bulbs going in from the side, and the LED bulb going in from the top. We think this makes the plants grow faster, as it seems plants would probably grow the best with the sun in a position imitating noon than imitating sunset or sunrise. We will probably need to adjust our experiment so that all the lights come in from the top. If you have any suggestions, please let us know.

Gabe

Will I think that the L.E.D. light is making the plant grow faster, now that I think about it, the L.E.D. shins more light then the other lights so the plants get more light to grow in. That is what I think.

KyleS

so I think that the LED light is working best for it looks most like the sunlight.

Chloe Pak Drummond

Hi Team,

That's great you're already getting some of the seeds to grow. Even though you predicted that the LED lights would make it take longer for the seeds to grow than regular lights, it seems like they are making the seeds grow faster than the red and blue lights. I know you had to stop the regular light experiment, but why do you think the LEDs are making the plant grow faster than just red or just blue light?

For the water, this can be a tricky problem. Sometimes people will put their plants into a shallow pool of water so that there is a constant source that keeps the soil wet, but I think this might make your cups soggy and it might actually be too much water for the plants! As long as the red, blue, and LED experiments are getting the same amount of water, I think you can still compare them, even if the soil gets dried out over the weekend.

so far only 2 of are plants have grown and bothe were under the LED light
