Final Product Margaret thank you for answering all of our questions and helping us out. Is there any thing else that you would like to know about our experiment? |

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. |

Research Conclusion Great answers to my question. Can you now complete your Research Conclusions? Based on your data and the figures (graphs), what is your conclusion? Is your Research Prediction correct? Think also about how you could improve this experiment i.e. if you were to repeat, what would you do differently? |

Answer Three elements most frequently found in fertilizers are nitrogen, phosphate, ans potassium. I also heard sulfur is an important element in fertilizer. If plants have too much of these elements then it stunts their growth. It relates because the use of fertilizer is important to everyday farming. this fertilizer affects our oceans and rivers after it rains by putting chemicals in the water. |

Project I like your ideas, maybe you can spruce them up a but with more details in your research question. What exactly are you doing? Are you testing if an amout of fertilizer affects the length of the seed? |

Good Answer What three elements are most freqeuntly found in fertllizers? What happens to plants when there are too much of these elements in the soil? How does this relate to growing plants year afyer year in the same soil with increased fertilizer i.e. think about what farmers? How does this fertilizer affect our oceans and rivers after rains? |

Answer The lower fertilizer seems to be working better because it gives off just enough nutrient to help the plants growth and development of height. While the high fertilizer is providing too much nutrient and causes the stunt of growth and development. This is what I think is happening and why the low fertilizer plants grow better. |

Mean Use the mean for each plant in the plots for each treatment. Therefore, you should have the heights for all plants in your low fertilizer treatment; do one mean for this treatment. Then do one mean for the other treatment. Why do you think that your low fertilizer plants are flowering before the high fertilizer plants? |

Update Should the mean be from all of the data of each pot or just the heights we have now? Our high fertilizer plants do not have flowers yet. We also lost a plant in our high fertilizer pot. It was pulled out. Our low fertilizer plants have started to grow pods on one plant. |

Flower buds What about the high fertilizer plants? Are they flowering? Once you have the mean heights (averages), you can then represent the data on a bar graph. |

Update The plants have flowers. The low fertilizer plants all have flowers or at least flower buds. |

Light The amount and quality of light does affect growth. However, the plants will eventually recover. If the plants are falling over, you may have to stake (tie them to a stake). Do you see any differences in the data that you are collecting? Find the mean for each treatment (low vs. high fertilizer). This will help you to see the data more clearly. Are they starting to flower as yet? |

update Hello Dr.Margaret Young, Our plants have grown very well and have gotten to a mature age. We couldn't control the lighting system but our plants are just fine now. Thank you for the suggestion and do you think if we couldv'e controlled the lighting system it would have made out plants grow better? |

update Dr. Margaret Young we are on day seven and are plants seem to be growing just fine. We are measuring the hieght of each live plant, how many leaves, and the color. Two of our plants are starting to sprout. |

Fertilizer Students, From your comments you have two treatments: high fertilizer and low fertilizer? What data are you taking? plant height? It may also be good to look at color of leaves. Also, ensure that the light is close to the plants; as the plants are growing move the light upwards. Please fill in your Research Predictions and Experimental Design. |

Update Our high fertilizer plants are doing worse than the low fertilizer plants. we think that the high fertilizer plants have too much fertilizer and this is causeing the plants to not do as well. we also switched the lights to see if that was our problem. the other classes' plants are doing better than ours. we measure our data every class period and we will be doing this for 6 weeks. |

Hypothesis Hello students, You should be thinking about what the past literature says that is, has anyone done similar experiments and their results? However, we can work together on this. What fertilizer rates (treatments) are you using? How many plants per treatments? How often are you planning to take data and for how long? The plants may be planted too deep (may take more time to germinate); also not every seed will germinate. Fill in the experimental design. |

Research Question We are not ready for our research question yet. Here is where we are at. I posted a picture to show you exactly. Both plants have 3 sproutlings. They range from 1.5 to 3 cm. One had a seed coat but fell off today. A new sproutling on the high fertilizer side also has a seed coat. Why do you think the others have not sprouted yet? the other teams have had their 6 all sprout. |

Hello Students Good to hear from you. Brittany - Genomics is the study of chromosomes, DNA, genes and the parts of the DNA that the function are unclear. Scientists are interested in the genes that cause diseases etc. and genomics help them to find the location on the chromosomes (they will eventually be able to fiugre which genes and traits are in ecah individual). They are also doing the same work with plants e.g. drought tolerant genes. Kristina - I am also excited about working with you and your group. Jaisha - plants can be identical. If you take a pice of stem from a plant e.g. a rose, and place in water to allow roots, this plant will be identical to the original rose. This is called asexual reproduction (cloning) and many plants do this naturally. Please fill in the Research Information. |

Hello Students I am Dr. Margaret Young and I will be your scientist mentor for this project. I teach plant biology primarily to undergraduates at Elizabeth City State University in NC. My research interests are plant tissue culture (cloning) and introducing new genes into plants. Please fill in the Research Information so that we can start the experiment. |

Welcome! I am happy to welcome you to this community of plant researchers. Your team has the opportunity to be mentored by a scientist to help you develop and perform your own research project. The mentor's role is to encourage and guide you through the scientific process of discovery. The more you share your ideas and research information online, the more your mentor can help. Your scientist mentor for this project will be Dr. Margaret Young from Elizabeth City State University. Please introduce yourself and post some possible research topic ideas to get a conversation rolling. These resources are available to help you get started: Thinking Like a Scientist / Working Like a Scientist Designing Experiments Guide to Using A Spreadsheet Best wishes as you start this scientific journey. We are all pleased to share this experience with you. Have fun! Sincerely, The PlantingScience team |
