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. Please come back and visit the PlantingScience Research Gallery Archive anytime to view this project in the future. You can search the Archive by key word, team name, topic, or school name. Good bye for now. Warm regards, The PlantingScience team |

New Overview -It seems that the “wet” plants have the most growth -Four seeds were planted - All four seeds of E2 sprouted; it is also the second tallest plant -E1 has the most growth; but only two seeds sprouted -C1 was the first plant to sprout, we were surprised that it was the first to sprout; unfortunately it died -The wet plants have the most growth |

Overview Although C1 sprouted first, it seems that the "wet" plants have the most growth, and healthiest appearance. E1 has the most growth. E2 has is the second tallest. It seems that the "wet" plants have the most growth. |

Okay, thanks for your suggestions. We were thinking the same thing, from now on the Control cups will receive 10ml of water and the Experimental cups will receive 25ml of water. Thanks! P.S. we will get back to you in about the overview. |

Hey Guys, Me again. I just look over your most recent journal entry. Could you give me a brief overview of what you are observing in each of the cups at this point? Thanks. |

Hey Guys, Your design looks pretty good overall. I do have a couple of suggestions. First, in a 250 mL cup, the difference for the plant between 10 mL or 15 mL is probably not that great. I would suggest increasing the 15 mL to 25 mL, which should be a more substantial increase in the amount of water in the cup (compared to the plants only receiving 10 mL). Second, where are the cups being stored and what is the source of light? Just make sure that they have a light source and that both groups receive the same light (and are placed in the same area). Other than that, it looks like you guys are on the right track. If you have any other questions, please let me know. Good luck! |

1) Yes, we will be measuring the length of our plant each day. We have a Quantitative and Qualitative data chart. 2) We will be growing them in the same, soil, light, and temperature, but they have different amounts of water. 3) The plants are receiving the same amount of light. They are sitting on a windowsill, that receives a good amount of sunlight. Thanks so much! |

Hello Folks, Your experimental design looks pretty good. But, I do have some suggestions for improvement. I'll come back to that shortly. I want to address your previous comments/questions first: (1) You said you will simply measure which plant had more growth. Do you mean you are going to measure the length of your plant? If that is the case, then the data you are collecting will be amount of growth per day? (2) My question about control groups refers to the fact that you need to eliminate as many variables as possible that affect growth OTHER than the one you want to test. That is, for example, both groups of plants should be planted in the same type of soil, receive the same amount of light, receive the same light quality, exposed to the same temperature, etc. Your experimental design seems to bear this out. The two treatments seem to be the SAME except for the amount of water you are adding. This is how the experiment should be set up. You want to make sure that there is nothing else that could explain growth rate EXCEPT for your independent variable (amount of water). And, it looks like you guys are on the right track. (3) With regard to your experimental design, what is your light source? If you are using fluorescent lights (or whatever type of light you are using), just make sure that BOTH groups of plants receive the same type of light. For example, don't sit one group on a windowsill and then sit another group on a lab bench with a fluorescent light shining on it. Make sure both groups receive light from the same light source. I hope all of that is clear and that the information helps out. Let me know if you have any other questions. Keep up the good work! |

Answers Here are the answers to your questions: 2) We think we will just simply measure which plant has had more growth 3) The wet soil will receive a good amount of water daily or possibly every other day (we have to research more about how much water is needed and how many days a week to water it)..The dry soil will have a little water, and it will be watered daily 4) Could you please explain this question more clearly 5) The plants will be grown inside, near a window, and we will have different fluorescent lights on it (example: ultra violet) -Thanks for your thoughts as you can see, will have a little more research to do |

Hello Folks Hey Guys, Great to be working with you. It looks like you have things rolling with your project. I would like to ask a few questions about your project and offer a few suggestions and general comments. (1) You have correctly identified your independent and dependent variables. That's great - you need to have these correctly identified before you begin your project. (2) How are you going to measure growth rate? Will you simply be measuring the length of the growing seedling? Or, will you use a different metric. There are a number of ways to assess growth, so you need to be as specific as possible when measuring. (3) When you say "wet" soil vs. "dry" soil, how "dry" are you talking about? Does this mean that the soil will receive no water at all? If that is the case, what is the likelihood that a seed on dry soil would germinate at all? (4) Could you please describe for me your control group(s) and experimental group(s). What are you going to be controlling in your treatments? You need to try to control as many variables as possible to rule out alternative explanations. Make sure that this is very specific. (5) WHERE will your plants be growing? Will they be outside or indoors? What is the light source? Those are my initial thoughts/questions about the project in its current form. If you have any questions for me, please don't hesitate to ask. I'm here to help, so please let me know if I can be of service. Good luck! |

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. Christopher Adams from King College. 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 |
