Info

Explore The two main parts of a chloroplast are the grana and stroma The green color of leaves is due to chlorophyll , what interest me about plant is are Plants the only organisms that use photosynthesis.
Research Question Does photosynthesis occur differently when the plant is a color other than green? We came up with this question by observing the color plant and thinking where do they get their colorful color from? This question fit with the topic in class the topic we were talking about is chlorophyll which is...
Predictions Our prediction is that photosynthesis won't change when the plant is a color other than green. It would depend on the amount of sunlight the plant gets.
Experimental Design We are going to observe the growth of the plants. The variables that will be tested are penta plants. The variables that will be measured will be the color of light. The variable that will be kept constant will be the water. We will record our data in our lab notebooks.
Conclusion To wrap it up white (natural) light height got bigger by 5 more centimeters, width got bigger by 2 cm, depth grow 2 more centimeters also. Blue light for height grow 2 cm, the width grows just 1 centimeter, the depth grows 2 centimeters. red light height row 3 centimeters, the width got smaller...
About this Project

In brainstorming their research question these students utilized phenomena they observed in class to design their experiment. Their data collection is reflected in their conclusion. They utilized the suggestions made by their mentor. Most importantly, they were amazed by the results of their...

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

No, I'm not surprised by the results. I think they grew the biggest in white light because they were used to it already. And thank you for being there for us when we needed you and with our project.

Yes, I thought the natural red or blue light would have a big difference due to the color but the white/natural light grew the biggest in my opinion I think because it doesn't have a strong color. 

Mara Breanne McHaffie

I see that you've wrapped up your experiment! Are you surprised by the results? Why do you think the plants in white/natural light grew the biggest?

Hello we are observing three pentas plants under 3 differents light blue,white,red, we measures the height ,the depth,the width, we will be measuring the different height of the leafs and how the light effects the plants.

    Mara Breanne McHaffie
    said

    Sounds good! How many plants will you be growing under each light? How many days will you be observing them?

    Be sure to post pictures of your plants if you can - I would love to see them!

Mara Breanne McHaffie
said

Hi everyone,

It's great to see that you've added to your project info! So it sounds like you're going to try growing mint plants under different colours of light. Is that right? That's very neat!

How many plants will you be growing under each colour of light? What will you be measuring so that you can tell if the light colour is affecting the plant? Will you measure the time it takes for the plant to produce a certain number of leaves? Or perhaps you'll measure the height of the plant regularly over a number of days? I look forward to hearing how it goes!

Please feel free to ask me any questions. I'm always happy to help out!

yh can color lights affect different plants of any kind of plants 

Lleira
said

I have been thinking that does currently different lights affect current plants or plants in general; like different plants, not a specific plant.

    Mara Breanne McHaffie
    said

    I see. So you're wondering if different kinds of light will have an effect on the plants? 

VanessaO

Hey Mara,

My group and I are doing an experiment on weather photosynthesis occurs differently when a plant is a color other than green. 

We were wondering what seed do you recommend we use?

    Mara Breanne McHaffie
    said

    Hi Vanessa! It's nice to hear from you and hear that you are developing your research question. That's a really interesting question!

    Before we talk about seeds, I'd love to understand more about your thinking behind the question. I see that you've noted that many plants get their green colour from chlorophyll. What other colours of plants can you think of? Do you think that these plants could have chlorophyll too, or only green plants? If these plants don't have chlorophyll, do you think they are photosynthesizing another way, or not at all? Lastly, I wonder if you have any ideas about what else (other than chlorophyll) contributes to a plant's colour?

    I'm also curious if you've thought about how you might test out your research question. How will you observe if/how photosynthesis is occurring?

    I'm excited to hear more!

    Regarding seeds, I suppose it depends what colours you are thinking of. For example, I know that different varieties of lettuce have different colours, so that's a possibility (you could use some seeds of a green variety, and some seeds of a reddish variety).

Hi everyone,

I'm glad we've all had a chance to introduce ourselves! Perhaps you can tell me a bit about what you've been learning in class about plants? Has there been anything that has surprised you so far? Is there anything you're curious about?

I hope you all have a great weekend! It's a long weekend here in Canada since we celebrate Canadian thanksgiving in October instead of November.

Hi Mara I´m Thanialie

My  favorite subject is Medical.

    Hi! Nice to meet you! Do you think you want to work in medicine when you're older then?

VanessaO
said

Hi Mara,

I enjoy reading books more than writing them.

Lleira

what made you go for biology?

    Mara Breanne McHaffie
    said

    I've always enjoyed biology in school, and I also grew up with a great love of plants, animals and the outdoors. By the time I finished high school, I knew that I wanted to pursue a career related to nature, and work in a job where I could spend time outside. So I chose to major in Wildlife Biology and Conservation. And now, in the job I currently work at, I get to help conserve and restore habitat and spend time outside surveying plants and animals. It's a lot of fun!

hi sorry for not introducing me but i dont have a computer in class but my name is Lleira but its pronounced jada. My name is actually spelled in spanish.  

    Mara Breanne McHaffie
    said

    Hi Lleira,

    Nice to meet you! I also really enjoyed math in high school. In fact, it was the subject that I did the best in. Math is actually quite useful for many branches of science, especially chemistry and physics.

VanessaO

Hi Mara,

My favorite subject is English.

VanessaO

Hi Mara, 

Yesterday we discussed where the mass of a tree comes from and the von Helmont experiment. Can you tell me about an experiment that you did which didn't work out as expected? Also what changes did you make after that? We learned that the mass of plants comes from air and water.

    Mara Breanne McHaffie
    said

    That's a great question! In a recent research project, I was sampling soil from different areas that had been planted with different types of plants. I hypothesized that areas planted with certain plants that had deep roots would contain more carbon in the soil. However, my results were really wacky - I wasn't able to detect differences between most areas, except for one spot that had super high carbon amounts in the soil. I couldn't figure out why. I'd like to redo the experiment and change a few things. First, I would increase the number of areas I sampled from. You may have learned that the larger your sample size (the more samples you take), the easier it is to detect differences between groups. I also realized that the carbon amounts were probably also affected by things like moisture and soil texture, which may have been making it difficult to detect the effect of the plants. So in redoing the experiment, I would also measure the soil moisture and texture so I could account for them when looking at the results.

actually my favorite subject is math also

Mara Breanne McHaffie

Hi team,

I notice that you've all joined the conversation now. Welcome! Perhaps you can tell me what you're working on in class so I know what stage of your investigation you're focused on.

Hey Mara,

My name is Vanessa, what's your favorite plant? What was your favorite subject when you were in school?

    Mara Breanne McHaffie
    said

    Hi Vanessa,

    Nice to meet you! There are so many plants - it's hard to choose! I really like a plant that grows near me called the sassafras tree. It produces leaves of 3 different shapes (one is an oval, one looks like a mitten and the other looks like a dinosaur footprint!) and the leaves can be very soft and fuzzy. If you scratch the bark, it smells like fruit loops! Extracts from the tree were traditionally used to make root beer. Overall, it's pretty cool.

    When I was in high school, I really like math and science, which is probably why I pursued biology in university. I just find the natural world so amazing and fascinating!

    What's you favorite subject?
