| Explore | Our group the sarcastic seeds know a lot about plants. Our group has lots of information about plants that we want to share. Our group knows how to plant, grow, water, and care for plants. Our group also knows about different species of plants. Our group knows a lot about plants. We learned some information about plants from class and different website or articles. From the articles we read, we learned that you have to break the experiment into parts, different ways to conduct an experiment, how to ask yourself questions, how to summarize data, and most importantly how to grow plants. We also have some questions about plants.How are plants affected by different levels of ph in the water and/or soil? What is the average time for plants to grow? What is the average germination time for plants? How do different fertilizer to water ratios impact the development of plant? The information, questions, and our back knowledge about plants are all subjects that our group want to explore and discuss. |

| Research Question | Our research question was how different amounts of light affects the growth of ryegrass. We are going to have three plants; one that gets an hour of sunlight, another that gets only six hours of sunlight, and the last one will get full sunlight. We are going to try to see how the different amounts of sunlight will affect the development. |
| Predictions | Our prediction is that the plant that is exposed to six hours of light will grow the best because it is not being dried out, overheated, and/or not being exposed to too little sunlight. |
| Experimental Design | In our project we are experimenting on how ryegrass grows better in different types of sunlight. We are going to grow the plants in plastic cups with about 1 1/2 cups of soil in them. There is going to be three pots with 10 seeds in them for every different amount of sunlight (nine pots and 90 seeds). We are going to be putting the cups in direct sunlight, sunlight for one hour, and sunlight for six hours. Or plants will be giving the same amount of water (30 ML or 20 ML every other day or every two days) and the same amount of sunlight per day. On weekends sense we don't have school we will be leaving them farther away from the sun or in the dark. The seeds will be planted 1/2 inch deep and we will be leaving some space in between each plant. We are growing the plants in potting soil and giving them natural sunlight. The plant that needs all the time sunlight we are just giving it sunlight for how long the sun is out. We are poked three holes with a wall tack on the bottom of the cups so the water can drain out. Under the plants we put mason jar lids so the water can't leak out. The window sill can get colder than when the plants are under the boxes. We will measure the temperature difference. The point of our experiment is to see which plant grows to be the most successful. We are measuring it by how big it gets, if it wilts, if it dies, and so on. At the end of our project we hoping to have a fully grown plant that grew better than the others. |
| Conclusion | In the beginning our group thought that the group that got six hours of sunlight would be more successful because it would get an average amount of sunlight. In the end our hypothesis matched up with our results. We found that B group and C was more successful than the other groups. A group had an ending height of 17.6 cm, B group had an ending height of 18 cm, and C group had an ending height of 28.3 cm. B group was also more successful because it was a nice medium green color and more stable than the other plants. C group was more successful because it was much more sturdy and a better color than the other groups. |
