| Explore | (What I knew about plants before I came to this class is that every plant needs water, sunlight, and minerals. Plants use photosynthesis to make food and sugar. What I learned in this class that plants can use polarity and little tubes to absorb the water through little tubes in the root. BW) ( In class, I learned that plants need water, sun, minerals, and bees. They need all these things to grow healthy; without one or more items, the plant starts to lose structure. On my own, I have discovered that small plants that don't have a wooden trunk or support are weaker and the roots aren't strong, and they are easier to pull out of the ground. One question that I have is why the small plants have green spouts, but other bigger plants have wooden trunks. Are they different classes of plants? C.O.) (What I know about plants from outside of school is plants need photosynthesis, which is when plants use the sun to create food for themselves, also that plants need sun and water. From class we know that plants need sun, water, bees and minerals. A question about plants that interests me is, is there a way to know how old a plant not like exact age but in the general area of that plants age? C.S) I do not know know much about plants outisde of school all i know is that you need to water it and let it get sun. I have discovered that plants can die if they get too much sun and too much water. Do plants grow better at a certain time of day? (A.P) |

| Research Question | Cs, Co, Ap. Does a seed grow better with cold or warm water? Difference will be 15 degrees, and it will be measured by the amount of basil leaves |
| Predictions | We think that the warm water plant will grow better then the plant in the cold water because the plants our in the sun so the warm water will become more effective and become room temperature quicker. The cold water needs to become warm before it is the temperature of the lamp. C.O./ C.S./ B.W./A.P. |
| Experimental Design | Our plan is to put are seeds in the sun and water them with different tempature water and see what plant will grow more leaves. How we do this is cut a plastic water bottle in half with the top end being a little shorter, poke a hole in the cap of the water bottle so water can come threw. Cut a piece of string that goes through the whole and touches the bottom. Put the bottom part of the water bottle standing up flip the top side upside down and put it in the bigger/bottom part of the water bottle. Than after all this put dirt in the top side of the water bottle so it almost fills to the top. Than in order to create sunlight you use a light to shine it on the seeds you put one inch deep in the soil. You put the water bottle in a crate wrapped with tin foil with a light shining in. That is how you create the experiment and than test your research question. Variables we will test are how the temperature of the water effects the growing of the plant/leave. variables we will measure is the temperature of the water we use. Variables that will stay the same are the amount of sunlight we give to each plant. We will record our data by writing it down or typing it on computer (C.S, C.O, B.W, A.P |
| Conclusion | The plants that are watered with warmer water grow to become taller and thicker. I think that this happened because the cold water damaged the roots. I believe that the cold water almost shriveled up the roots, so they could not have absorbed as much water. It also could have been that the warm water was more soothing, and therefore the plants wanted more. I also did realize that every time we went back to water the plants, there was much more water in the cold plant than in the warm plants. The watered plants with warm water were the same, if not bigger, as the control plants. These were the " Normal plants." The cold plants were smaller than the warm ones. In the future, to expand on my experiment, I could test a more specific temperature. Now that I know that the warm water grows better, maybe we could try the temperature against an even hotter temperature. (C.O.) |
