Results! Hi there, Your results are interesting! Maybe you could make a graph of the changes in a quantitative trait through time - perhaps the proportion of healthy to sick leaves? |

Just so you know, all of the days and observations are in one journal file to make it easier. |

Ok that sounds like a good idea, we will do that. :] |

Good! That sounds like a good design - you're going to be essentially testing the effects of short-term acclimation on photosynthesis. Since photosynthesis can ramp up and down fairly quickly, I'd recommend having the solutions the leaf discs will go into at temperatures equivalent to those the plants experience, so you aren't shocking the leaf discs with another temperature. :) |

Ok well my group and my teacher helped decide that during the full school day we will keep the plants in the sunlight, then at the end of the day (2:40) I will put the warm plants under tin foil (to keep the heat in and sunlight out), then room temp will go in a cabinet and finally the last one will just go in the fridge. Leaf disk test and thymol blue tests we will do basically what you said, but we barelly got to do a demo of it so i would assume thats what we will do. We also have a paper describing it but currently i do not have it with me. We have pre-grown pansies, two for each temperature. They will be in the temperatures from the end of my school day, through the night, until the next morning when I get to school. |

Cool! That sounds great! One thought - how are you going to control the light that each treatment gets? It is important to hold all other variables constant besides the one you're investigating. If you don't, we say the multiple varying variables are "confounded", and you can't tell which variable caused the effect. Will you use lights? Can you explain the leaf disk and thymol blue tests? Are you going to submerge the leaf disks in water and measure the change in pH as CO2 is absorbed and O2 is released. Are you growing the pansies from seed, or using pre-grown plants? How long are you going to keep them at the given temperature? How many plants are you going to assign to each treatment? |

Hi again. Well we decided that we would use three temperatures 1)cold [refriderator] 2)room-temp [classroom] 3)warm/hot [greenhouse] We have pansies as our plant. To measure we already have to given tests that we have to do, a leaf disk and thymol blue tests on the leaves. My group and I also figured that we would use a ruler to measure how the plant has grown over the course of the week(s). Thats about it so far. |

Research Topic Hi everyone! I see you've put up a research topic! The effects of temperature on photosynthesis (as measured by plant growth) is a great topic to investigate. Now that you have an idea, you need to think of a few things: (1) What kind of plants are you going to use? (2) What temperatures are you going to test? (3) How will you alter the temperature? (4) How will you measure growth? (Height, # of leaves, etc) Think about these given what supplies you have available and we can plan a solid experiment. :) Also thanks Jessica for answering my questions! I actually study photosynthesis in sunflowers, it's one of my favorite topics. |

Hi. I'm Jessica R. 1)My favorite plant is the magnolia tree because i grew up with one in my grandparents yard and always loved picking the flowers out of it and watching them bloom, even though its the tree i broke my arm from. :] 2)The topic i like most from plants is photosynthesis mainly because its the one I've learned and heard about the most. |

Hi there! Hi everyone! My name is Chase Mason, and I'm a PhD Candidate in the Dept. of Plant Biology at the University of Georgia. I study adaptation to stressful conditions (drought, low nutrients, salt, etc), using wild species of sunflowers as my study system. I look forward to working with you all! To get started, could you all please introduce yourselves, and tell me (1) what your favorite type of plant is and why, and (2) what topic you find most interesting when it comes to plants specifically, or biology in general. :) |

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 Chase Mason from University of Georgia. 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 |
