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 |

I'm glad you enjoyed working with C-ferns - they are really interesting plants! It was great hearing about your project. |

The water where the sperm was released the slowest was the hot water measured at approximaly 102 degrees fereignheight the differance was about 1.1 seconds. I don't think the rain water is as cold but it definatly i think is cooler then room temperaure. I think this resulted this way because they are released through rain they have to be adapted for the cooler temperatures. Thank you for your time and help through out this project i enjoyed learning new things about the plants. |

A few more questions Hi team! Interesting results! Totally not what I would have predicted. At which temperature was the sperm release the slowest, and how much slower was it? I have a few more questions for you. In your prediction, you make an assumptions: that rain water is cool. C-ferns are originally from warm, tropical areas - do you think rainwater there is as cool as your experimental conditions? That being said, do you have any ideas that might explain your results? |

update today we tested our hypothesis and found the sperm come out faster in the cold water we did this by taking 9 slides and putting the males on them. We then took three slides for each temperature range three for cold three for room and three for hot. We then put them under the microscope and dropped two drops of the water on each one at a time and timed it. |

Journal questions You have some really interesting questions in your research journal. Are you doing some reading and investigating to answer them, or are you asking me? I'm happy to answer, but I don't want to take away the fun of looking for answers. |

Great start! Nice images of your spores! It sounds as if you have a good experimental design, but can you clarify a few things for me? You have four cultures and three temperatures - are two of your cultures at room temperature? Which of the three temperatures is your control? I really like the idea of video capture of the swimming sperm - that's cool. I've never done that, since most of the research I've done is on plants that have been dead for a really long time! Once you have your videos, how are you going to actually measure how fast the sperm are swimming? I apologize for the delay in responding. Evidently there has been some problem with my getting updates about your project, so I will try to check our page more frequently. I look forward to your next update. |

Our question we are currently culivating 4 cultures. We think we should have one colder then room temperature maybe 60 degrees one at room temperature and one at 90 degrees. We could use video analysis in logger pro and we will video the sperm swimming to get a swimming rate. |

Interesting Question! Hi TJ, Brittany & Mo, I think you have come up with an interesting question. It looks as if you have a good population of spores in your plate(s) (how many cultures are you cultivating?). Can you tell me about your experimental design? How warm will the water be? Do you have a way to measure how fast (or how slowly) the sperm are swimming? I look forward to hearing more about your project! Cheers, Sharon |

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. Sharon Klavins from University of Wisconsin-Platteville. 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 |
