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 |

What types of trays are you using? Are they the kind with 6 or 9 cells each? Each seedling only needs a few milliliters of water per day if it is planted in shallow soil. If the soil is deeper, then you will need more water. The soil should be moist to the touch. It is difficult to quantify color. I would photograph the plants against a white background a few times each day as a supplement to your Excel data. April |

Ok guys! Now if you've settled on an investigation you should begin to describe what you are doing in your proceedures section above. Tell us how you are making it a 'fair test'. BTW do you think the colors will change the plant to the color of the dye or to some other color? Do you think the whole plant will change or just one part of the plant? Keep up the good work! |

Hi class, Sorry it took me a few days to write back. I was traveling. I don't mean to leave you hanging! :) As for your project ideas: 1) Does putting food coloring in the water and soil affect the color of the plant? This would be pretty straightforward to test. You could grow several plants of one species (you could choose, for example, tomato, lettuce, bean, or pea) with different food colors in their soil. The tricky part is that it would be hard to make sure that the food coloring didn't get washed through the soil and out the pot. 2) Does seed size(matter) affect the shape or groth of the plant This is a good one, and it would be easy to test. You could find (or purchase from a seed rack) seeds with a variety of shapes, making sure you have several different species representing each seed shape. Then you could plant them all in a controlled setup (same soil, temperature, humidity, etc) and compare the shapes of the plants that germinate. One thing, though, is that the plants will probably germinate at different rates, so you'll want to record the plant's shape and size as it grows (perhaps every day) with drawings, measurements, and photos. 3)How do seeds grow with out soil This one is much more complicated because there are many different ways in which plants can grow without soil. Usually these plants have special adaptations that allow them to do so. Most plants can't survive for very long without being in soil. That's all for now -- those airplane rides sure are tiring! Until next time, April |

Hey April, we are kinda thinking of different questions. we were wondering if you could help us figure out which question is easiest and most fancinating. We already posted them but i will type them anyways. 1) Does seed size(matter) affect the shape or groth of the plant 2)How do seeds grow with out soil I hope u can help us figure it out, By Kyla, Brandon, And Carmen |

team question Does seed size (mass) matter to the growth? Does changing the soil matter to the speed of the seed germination? |

Hi Carmen, My name is April, and I am one of the people mentoring your team. Your question was about how we know plants reproduce sexually, even though the seeds only come from one plant. Sexual reproduction in plants means that In order to get a seed, fertilization must occur between a sperm cell and an egg cell. In plants, the sperm and egg can come from the same plant (this is self-pollination) or from two different plants (cross-pollination). When a pollen grain (containing sperm from the male) lands on the stigma (the receptive female organ), it germinates and grows a tube that travels down the style (the "stick" part connecting the stigma to the ovary). Once it reaches the ovary, the sperm fertilizes the egg, which eventually becomes a seed. I hope this clarifies things! April |

Appropriate use of the 'Comments' area. Hi guys. I'm glad to see some of you adding comments to your team page. Just remember that this is a public area and so all posts need to be appropriate for an open conversation that everyone participates in. Please keep your conversations focused on the investigation work you are doing. Save all your general conversation and comments for when you are at home on Facebook. :) If you haven't chosen a name for your team, do so and upload it now. If you haven't selected an avatar/picture to represent your team, do so now. If you haven't introduced yourselves to your mentor yet, give them a brief introduction. Lastly, be sure to have at least one person from your team post a comment that tells your mentor the investigation question or questions that you are considering for your investigation. Your mentor has a lot of experience with investigating plants and will be a great resource for you! |
