Good bye Thank you to everyone who participated in this inquiry. We hope you are going away with some new insights about how science works, and confidence that you can take on new scientific challenges. There are a lot of fascinating research questions---just waiting for young investigators to join in the fun. Best wishes for the remainder of your school year! |

re:good work cool cotyledons! The corn seeds and the pea seeds did have a difference in the germination rate. The pea seeds had a higher percentage of germination and the corn seeds had a much lower germination rate. there was a differece in the results of the acid and control. In the acid the seeds germinated more but in the control all of the seeds germinated. |

Good Work Cool Cotyledons! Your experiment looks like it worked great. You successfully tested your hypothesis and made a conclusion statement. How did the results differ between the corn and pea seeds? Was there a clear difference between the acid and the control? |

Journal entry 1 Corn seeds- bright yellow with red and brown spots. Pea seeds- light green, yellow, and bright green, mushy. Analysis-the control seeds in water are growing the most and the ones in baking soda are growing the least. seed type % of germinating seeds day3 day4 day5 pea seeds 48% corn seeds 60% pea seeds in vinegar 32% corn seeds in vinegar 32% pea seeds in baking soda 24% corn seeds in baking soda 0% |

procedure Lab: Germination Objective: Does having a seed in an acid or a base affect the germination? Materials: 6 Petri dishes, 6 wet paper towels, pipette, 250ml beaker, 75 corn seeds, 75 pea seeds, strainer, paper towels, goggles, scissors Procedure: 1. Fill beaker with 175ml of water. 2. Add the 150 corn and pea seeds to the beaker. Allow the beaker with the seeds to sit over night. 3. Strain the seeds from the beaker. Pat them dry with a dry paper towel. 4. Divide the seeds so that you have 2 piles of 75 corn seeds and a pile with 75 pea seeds. 5. Label one Petri dish – pea control(use only water in this dish), one Petri dish- corn control(only water), one dish corn in vinegar(use only vinegar), one peas and vinegar(only vinegar), one peas and baking soda(only baking soda solution), one corn and baking soda(only baking soda solution) 6. Take six paper towels with. Cut out twelve circles of paper towels wet the paper towels with water. Put one circle in each of the Petri dishes on the bottom. 7. Put 25 corn seed in 3 Petri dishes (25 per dish). Put 25 pea seeds in 3 different Petri dishes (25 per dish) 8. Take the other six paper towel circles and put them on top of the seeds 9. According to step 5 wet the paper towels with the correct liquid. Use a pipette to wet the paper towel as the paper towel dries. (About once each day). 10. Take the baking soda solution and put some of it on 1 Petri dish with peas and one Petri dish with corn. 11. Take the vinegar and put some of it on one Petri dish with peas and one Petri dish with corn. 12. Record the number of sprouting seeds for the half seeds and the seeds with the hole in it in the table below. Observe the seed growth. Data seed type % of germinating seeds day3 day4 day5 pea seeds 48% 56% 68% corn seeds 60% 64% 80% pea seeds in vinegar 32% 44% 60% corn seeds in vinegar 32% 52% 76% pea seeds in baking soda 24% 60% 68% corn seeds in baking soda 0% 12% 28% type of seed length of seed root day 3 day 4 corn control 2 4-5 pea control 1.5 2 corn in vinegar 1 2 peas in vinegar 0.5 1.5-2 corn in baking soda 0.2 1 peas in baking soda 0.4 0.5 |

lab we chose the essential question: do seeds germinate faster in an acid or a base? our teacher told us that the lab report we made wouldnt work. she told us that we didnt have to make a new one. since we have a guest speaker we will not observe our seeds until wednesday. |

lab procedure Lab: Germination Objective: Does cutting a seed in half affect the seed’s germination? Materials: 4 Petri dishes, 4 wet paper towels, pipette, 250ml beaker, 50 corn seeds, 50 pea seeds, knife, strainer, paper towels, goggles, safety pin, scissors Procedure: 1. Fill beaker with 175ml of water. 2. Add the 100 corn and pea seeds to the beaker. Allow the beaker with the seeds to sit over night. 3. Strain the seeds from the beaker. Pat them dry with a dry paper towel. 4. Divide the seeds so that you have 2 piles of 50 corn and a pile with 50 pea seeds. 5. (Use goggles) laying 25 pea seeds and 25 corn seeds flat and cut all of them in half with a knife. 6. (Use goggles)Laying 25 pea seeds and 25 corn seeds flat, use a safety pin to make a small hole in the 25 pea seeds and 25 corn seeds. 7. Wet four paper towels with water. Cut out four circles of paper towels. Put one circle in each of the Petri dishes. 8. Put the corn seeds cut in half in one Petri dish, the 25 pea seeds cut in half in another Petri dish, the 25 corn seeds with the pin hole in another Petri dish, and the 25 pea seeds with the pin hole in the last Petri dish. 9. Leave the seeds to germinate for one week. (Keep the dishes where they can get sunlight). 10. Use a pipette to wet the paper towel as the paper towel dries. (About once each day). 11. Record the number of sprouting seeds for the half seeds and the seeds with the hole in it in the table below. Observe the seed growth. Data: seed type number of sprouting seeds 1 2 3 4 5 6 7 corn half seed corn pin hole pea half seed pea pin hole Variables: corn half seed, corn pin hole seed, pea half seed, pea pin hole seed, corn seeds, pea seeds. Controls: amount of water, sunlight, temperature, and number of seeds per dish. happy halloween! |

Happy Halloween!! Hi Cool Cotyledons, I am so happy to be working with you all. Your questions are a great start. How are you going to choose from so many great ideas? I especially like questions: 3, 4, 7, and 9. Feel free to send me any questions about your project from the planning through the conclusions phases of your project. Good luck and have a great Halloween. Frank |

essential questions #2 These are the 9 Essential Questions we will be choosing from: 1. Does Climate destroy certain types of plant seeds? 2. How do certain plants grow in shade? 3.do monocots or dicots germinate faster? 4.Does carbon dioxide make germination go faster? 5. Is germination effected when the seeds are in o.j.? 6. Can a seed germinate if it recieves no moisture? 7. If you damage the seed coa t does it affect germination? 8. If you cut the seed in half can the seed still germinate? 9.If you were to put a seed inside any type of acid, would it effect the plants germination? 4. |

Dr. Claire Hemingway
Hello and Welcome to PlantingScience! Hello St Sebastian Team 5, Welcome to the community of science researchers. We enjoyed talking with St. Sebastian teams last year. We are so glad your team is joining in the fun of plant investigations. I would like to introduce you to your scientist mentor, Frank Farruggia of Arizona State University . Expect a hello here soon. Then he will give your team feedback as you plan and carry out your experiments on seeds. He might even share some of what she finds so exciting and interesting about studying plants. Don't hesitate to ask questions or share your brainstorming ideas. Getting started can be one of the hardest phases. But I know you are lucky to have a wonderful teacher and a wonderful mentor to help. Best wishes as you begin this scientific journey. We are looking forward to sharing this experience with you. Regards, Claire Hemingway |
