Mr. Bill Dahl
Thank you for your time! Hi Cotyledons On behalf of the organizations involved (see the list at the bottom of the page) and the entire PlantingScience team, thank you for spending some time with us. I sincerely hope you are going away with a better understanding of how science, and scientists, actually works. Experimental design, control, variables, repetition, trials, predictions, monocot, dicot, germination, data, data, data…. What a fascinating and exciting subject – I’m sure you’ll agree science really is pretty amazing when you get in, learn the language, and then design and run your own experiment! We hope to see you back again sometime soon. Abby, thank you for taking the time to act as a mentor to the Cotyledons team! - Bill |

Research Conclusions Hi Cotyledons! You have done a really great job with this research project! I enjoyed reading your lab journals with your different perspectives on the experiment. I had a question about your conclusion, though. I certainly agree with what you say about knox gelatine and jello. However, it seems from your data that seeds grow best in plain water. Do you think this is because the seeds "don't like" the protein or because the texture of the knox gelatine is difficult for them to grow in? Abby |

fungus Hi Cotyledons! I wonder if the fungus grew better in the jello because of the added sugar and that allowed it to grow on the seeds? Also when the seedlings are actively growing, it would be harder for a fungus to attack them since they will be able to defend themselves somewhat. However, seedlings can't defend themselves as well as older plants can. Abby |

Hi Cotyledons! I'm looking forward to seeing your graphs, conclusions, and picture tomorrow! It sounds like the millet seeds must have been growing well in the knox gelatine! Do you think this was because they had more light (or maybe less light, if the other seeds had too much light), because of the knox gelatine, or something else? Of course, the millet seeds in the other treatments might have grown as much, but in a different direction. Abby |

Sprouting! Hi Team One! That's interesting that the seeds sprouted best in distilled water, second best in knox gelatine, and not at all in jello. Why do you think that is? Do you think the color of the jello and gelatine could have affected germination? Sometimes less light (or light of the wrong color) will cause seeds to "think" they are buried too deeply in the soil to sprout. Abby |

Lab Entry#2 Lynn's Lab Entry The millet seeds in the knox gelatine and distilled water have completely sprouted. The millet seeds in knox gelatine and distilled water are lighter in color and larger in size. The millet and clover seeds in jello have not sprouted at all. And the clover seeds in distilled water have completely sprouted and the clover seeds in knox gelatine half have sprouted, and the seeds are darker in color and larger in size. |

Yesterday.... Yesterday, we compared the wet seeds to the dry seeds to see change. The millet seeds in the knox gelatine and distilled water have completely sprouted. The millet and clover seeds in jello have not sprouted at all. And the clover seeds in distilled water have completely sprouted and the clover seeds in knox gelatine half have sprouted. |

Beginning of the Experiment Hi Lynn, Tim, George, and Taylor! It sounds like you've made a good start to your experiment! I'm looking forward to seeing if you start to get germination tomorrow. Are you mixing different amounts of knox gelatine and jello in your two amounts of water (so the ratio of jello to water is the same but the overall amount is different) or are you mixing the same amount of jello in two different volumes of water (so the concentration of the jello is different)? When you first soaked them, the wet seeds were larger than the dry seeds because the cells in the seeds took up water and got bigger. So at that point the seeds hadn't actually started to grow (by actually making more cells) yet. But probably by the time you read this, the seeds will have started to grow! Why do you think soaked clover seeds are darker than dry clover seeds but soaked millet seeds are lighter than dry millet seeds? Abby |

Lab Entry #1 Lynn's Lab Entry First we mixed knox gelatine and jello in two different beakers for each: 100mm of water and 150 mm of water. WE let the jello and knox gelatine set. We then soaked the millet and clover seeds in distilled water and let them sit for 24 hours. We then cut paper towels into to the same shape as the petri dishes. We then distributed the seeds in labeled petri dishes (6: 2 for knox gelatine, 2 for jello, and 2 for the distilled water). The differance between the wet and dry seeds: -Clover The clover wet seeds are darker in color and larger in size. -Millet The millet wet seeds are lighter in color and larger in size. |

Lab Entry #1 Tim's lab entry We mixed the Knox gelatine and J-ello in a beaker of 100ml of water. We let it sit for 24 hours, then we soaked th millet seeds and the clover seeds in distilled water. Finally we put the seeds in J-ello, Knox Geletine and water(for a control.). Differences Between the Dry Seeds and the Wet Seeds -Clover- The wet seeds looked bigger and darker. -Millet- The wet seeds are bigger and look lighter that the dry seeds. |

Lab Journal Entry #1 Taylor's Lab entry We mixed jello and knox gelatine in a beaker of 100 mm of water and 150 mm of water. We then let it set over night. We soaked millet and clover seeds in distilled water. We then cut papper towel's into the same shape as our petri dishes. We also labbeled the petri dishes on what was going to be inside them. Differance between the dry and wet seeds? >Clover The clover wet seeds are a darker color and they are bigger. >Millet The Millet wet seeds are a Lighter color than the dry seeds. The wet Millet seeds are aslo bigger than the dry seeds. |

Looking good. Hi Team One! I think you might want to just put the seeds on the surface of the jello. It's possible that pushing them into the jello each day would hurt the seed if it's already starting to sprout. I think the seeds will get enough moisture just being on the surface. Oh, and you can call me Abby if you want. I'm a student too, after all. Abby |

Hi Ms. Abigail Moore! We are planning on using red j-ello and clear knox gelatine. We don't believe that the color of the j-ello or knox gelatine will affect the rate of germination. We were also wondering about how to put the seeds in, should we sprinkle them onto the j-ello or should we push them down each day? |

Nice project! Hi Team One. I think your procedure looks good! Are you going to have more than one petri dish per treatment? In experiments these are called replicates. When possible, scientists like to have at least one replicate. In your case, there might be something about the place you put your petri dish with the jello that causes the plants to grow better. If you had two petri dishes for each treatment, you could alternate them (gelatine, jello, gelatine, jello) incase one part of the experiment got more light. What color is your jello? You might want to think about making the gelatine the same color with food coloring. The color of light seeds receive is sometimes important to how fast they germinate. Looks good! Abby |

Ms. Abigail Moore , We are very sorry our procedure wasn't sent on monday ,but it wasn't ready. Here is our procedure: 1. Boil 100 milimeters of water in two different beakers. 2. Put a gram and a-half of both jello's in a beaker. (knox gelatine and J-ello) 3. Mix the j-ello and knox gelatine with a spoon until the mix is completely disolved. 4. Let the mix cool down. Then pour the mix into the patry dish. 5.Cover the dish and let it sit for 24 hours. 6. After 24 hours, sprinkle the seeds on top of the two different j-ellos. |

I think Knox Gelatine would be an excellent control for your jello experiment! I assume the Knox Gelatine is clear. What color of Jello are you going to use? Do you think the color of the Jello could affect germination? Abby |

For the jello test, we found a control. We were thinhking to use Knox Gelatine which is pure protien vs. jello which is protien and carbohydrates. We are assuming that the sugar would be the nutrient. |

Hi Team One! It is difficult to say which of your two questions would be better to test for the experiment because they both sound very interesting! What about Jello do you think would affect the rate of germination, added nutrients, more moisture? It might be difficult to find a non-Jello treatment where everything else was exactly the same except for the one thing you really wanted to test. I think it might be easier to answer your first question, where you look at the difference between seeds that are grouped together and seeds that are spaced out. But I am sure that you could get the Jello experiment to work also if you decide you would rather do it. Either way, I think you will get interesting results. Abby |

Our team is debating on which essential question we would like to do. It is between the questions where seeds that are grouped together vs. ones that are spaced out. The other one is how does jello affect the rate of germination. Which one do you think would be better for this experiment? |

Interesting Questions! Hi Group One! You have come up with some great questions! You have clearly thought about this a lot. I don’t know whether seeds that were grouped together would germinate faster than seeds that were spaced out. At least some already sprouted plants can tell if there are other plants growing nearby. Sometimes plants can even tell that their neighbors’ leaves have been eaten and make their own leaves taste worse to animals to avoid getting eaten themselves! What do you think worms would do to the seeds? They might make the soil nicer for the plants or they might possibly bury the seeds so deeply that they couldn’t sprout. I am looking forward to finding out what you decide to investigate! Abby |

Group ones essential questions Do worms affect the rate of the seeds germination? Will a seed that its temperature changes germinate faster than seeds that stay in the same temperature? How will the germination of a seed get affected by salt water or fresh water? Do seeds that are grouped togeather germinate faster than seeds spaced out? Would a seed that is watered daily germinate faster than a seed that is watered every other day? Does Jello affect the rate of a seeds germination vs. a seed that has fresh water? Does a seed that is watered with a certian liquid ( milk, juice, pop, etc.) germinate fatser than one watered with fresh water? |

Welcome Lynn, George, Taylor, and Timmy! Welcome to Planting Science, Lynn, George, Taylor, and Timmy! I am excited to start working with you as you design your experiments about seed germination. Please ask me any questions you have about your experiment or about botany or science in general. Now to let you know a little bit about me. I am a graduate student and for my research, I am studying a group of plants called gumplants. They are called gumplants because the area around their flowers is very sticky, probably to keep insects from eating the seeds. Gumplants grow in marshes, in grassy areas, and on the seashore. I am trying to understand how they can grow in all these different places. I am looking forward to reading your essential questions next week! Abby |
