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 |

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. |

Measurements and data Hi Dream Team! I looked over the power point presentation that you uploaded to the website. Do you have time to conduct this experiment again? If so, I think you need to refine your methodology to be more specific about what you are observing and measuring. It is not clear to me what kind of data you were collecting. From your results, it looks like you were observing the height of the plants. But what is germination? Were you measuring germination rates? You didn't explain how you were doing this in your power point. Also, can you please add your data to your power point? Even if you think your results are inconclusive, you need to present your data. A graph would help us understand what happened. And don't worry, inconclusive data can be interesting! I wish we had communicated more often while you were setting up your experiment so that I could have helped you more. If you have time to repeat the experiment, please let me know and we can work together to improve your design. I hope to hear from you soon, Morgan |

Experimental design & research conclusions You have a lot to finish up here Exp. design--list materials and steps to complete experiment journals and data---graph & chart & description research Conclusions--explain your data and what it means to you. Presentation--explain experiment and offer further research at the end--ppt or photostory work well I really like this experiment and cannot wait to see your presentation |

Replication Dear Dream Team, My name is Morgan and I'm a graduate student at Cornell University. I study how people manage the wild plants they gather for food. I work with Native American elders in North and South Dakota and farmers in Ethiopia. I just finished my Master's degree and I'm starting research for my Ph.D. I like your research question! You might make an interesting discovery. One way to make sure your experimental results are strong is through replication, which means you repeat the same experiment many times to make sure any differences you observe are caused by the factor you want to study. If you think about it, there are many reasons why mung beans might germinate faster or slower, and some might never germinate, even in ideal conditions. Let's say you only have one seed planted in soil with an electric current and one seed planted in soil without any current. Imagine the one with the current never germinates. What conclusion would you make based on this observation? I hope you think about this problem as you design your experiment. It's nice to meet you and I'm excited about your experiment! Morgan |

Experiment Setup We have a general concept of how to set up this experiment. We need your advice on how to make it work correctly. We are planning on using a 9-Volt battery and connecting an electrical wire into 2 ends of the soil. The soil contains the Mung bean seed. We plan to keep the soil moist at all times in order to keep the current flowing. Please let us know if there is a more efficient way to do this. Thanks! |

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. Have fun, and remember the entire digital world sees your work and comments. Your scientist mentor for this project will be Morgan Ruelle from Society for Economic Botany. Please introduce yourself to your mentor to get a conversation rolling and post some of your team's brainstorming ideas and interests in investigating germination. 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 |
