Info

Explore Without previous knowledge of plants outside of school we know that plants need sunlight and water to grow. They have roots that help ground the plant, we also know they reproduce by producing flowers and spreading pollen. In school we learned that all plants go through photosynthesis and that...
Research Question Does the amount of fertilizer effect the phenotype of the plants being grown (plant height, leaf size, color of the stem and leaf, and trichomes)
Predictions Plants with more fertilizer would have greater growth, have darker leaves, and produce more seed pods.
Experimental Design We followed all the guide lines for planting the seeds given to us through the planting science site and only altered the amount of fertilizer between two groups. We gave one group four times the amount of fertilizer as what was considered normal, the other group received the normal amount ( 6...
Conclusion We can accept our hypothesis because there was a color change within the leaves and saw the same amount of growth within all plants. Plants with less fertilizer had more yellow leaves and the ones with more fertilizer had more green leaves.

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. 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.
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.

Those are great choices! Do you have any predictions about what the offspring will look like?

Today we decided on the plants we were going to cross pollinate, we are doing Purple/ Green with Green/ yellow and really hairy with hairless. when we got to school after the weekend a good bit of our flowers had actually pollinated themselves, so we had to choose ones that had not been pollinated.

Hi all! I hope that your test went well :)

Also, I'm glad to hear that the plants have flowered! That's great news!

I'm not sure exactly what you want to know more about regarding the pollination. Are you making "bee sticks" to pollinate with? That method works really well. Let me know if you want more information about how to do that. Or, were you asking about which plants to cross pollinate? If that was more of your question, I like the idea of crossing two plants with very different traits. If you do that, what traits would you expect the resulting offspring to have?

A lot of our plants have flowered. we had a test today, but we are going to measure out trichomes tomorrow. we are about to cross pollinate them and we have to figure out what traits to pollinate for. we can try and get a plant that is purple with yellow leaves or even a green plant with green leaves. We would love to hear your imput on how we should pollinate them.

Hi team,

Great to see those buds! You should have flowers very soon!

I was just wondering if you noticed any traits that are more different across the individual plants. For example, maybe all of the plants have approximately the same number of leaves, but some plants have purple stems while others have green stems. In that case, I would say that stem color is particularly (more) variable relative to leaf number.

I believe that the plants you are growing are expected to have some traits that are variable because the parents used to generate the seeds had different traits. Do you know what any of those traits are? And, do you see that pattern in the plants?

Please let me know if my questions are confusing, or if you have any other questions.

Cheers,

Kate

what do you mean when you say particular traits and what are some we should look out for. Thank You

Oh - that's great! Your plants look really healthy! I'm excited to see what the flowers look like. Have you noticed any particularly variable traits in the population so far?

Hi! It sounds like things are going very well! That's awesome!

Using the sticks to support the stems was a very good idea. It's really common for plants that are grown indoors to need a little extra support (in at least some plants, stems don't produce extra supportive tissue unless they experience wind and usually there isn't too much wind indoors!).

Also, did you add the fertilizer to all the seedlings or only to some of them?

I'd love to see photos next time if you have the chance to take some!

Best,

Kate

Hi! Today we got our plants and made more observations, we measured the stem height and the width and length of our true leaves. We did do a nutrient treatment by adding extra fertilizers. I'm so excited to see them grow even more! We even used thin wooden sticks to help support the stems from falling over and also support the ones that have already fallen. We noticed that our flower buds are showing up so we should soon be seeing some flowers! Maybe next time we get to observe them we can send you pictures.

It's great that your seedling are growing and that true leaves are starting to come in! 

Are you guys doing a nutrient treatment or simply looking at the F2s in one environment? 

Destiny

Today we measured our leaves and stems, created tables. some of our stems fell over, maybe because they were too heavy. we believe the color will stay the same, and we observed that some of the leaves have changed colors.  We noticed that our true leaves came in

Hi! That is great! It sounds like things are going well and that you have a good plan for measuring traits going forward. What are you expecting to see happen with the plant color/anthocyanins? Keep up the good work!
