| Explore | WCIII, Roots absorb water then the water evaporates after being used by the plant. The plan will change color based on the water. Plants need a certain amount of water RSP, plants are a part of photosynthesis, plants produce chlorophyl VPIV, I used to be a part of boy scout. One of the things you had to know to move to a higher rank was poison plants. We learned which ones were edible and what was best for rashes and burns. Tiernan, Some things that I know about plants are photothinsathis which is when a plant reperduces using the environment to help them reperdice. The plants also I know the way they live they use their roots to collect water and nutrients from the soil. the plants also get sugar from chlorofil which land on the leaves. |

| Research Question | Does sand vs potting soil affect the height of basil plants seeds? |
| Predictions | We think that the soil is a better base. |
| Experimental Design | We are giving our plants the same amount of sunlight and water but on different bases (planting soil/sand.) We have control plants, Japanese Spruces in both of our soil types and we have basil seeds growing as well as our main project. |
| Conclusion | WCIII- 1. What claim can we make from our experiment? My group can make the claim that different plants grow different heights in different bases. We can back this up because we planted 2 Japanese spruce seedlings (one in soil and one in sand.) We also planted two basil seeds (one in soil and one in sand.) The Japanese Spruce in sand grew up to 7.3 cm when our Japanese spruce in soil grew 5.2 cm. Our basil plant in soil grew two times as high as our Basil in sand (3 cm. to 1.5 cm.) We gave all our plants the same amount of water so can concur that different plants grow better in different bases. 2. What are possible explanations for our results? An explanation for the results could be that a plant was tipped over. This is highly likely because many plants were tipped over because of the small space we had to put our plants so they would be under the UV lights. There were two times I had to replant our Japanese Spruce in soil and one time I had to replant our Basil seeds in sand because they were tipped over. 3. How do the data we collected and our reasoning with scientific ideas support our claim? The data my group and I collected and our reasoning with scientific ideas support those plants grow better in different conditions. This is because certain plants have adapted to the places that they live. 4. What future experiments could be done to expand on the results of this experiment? A future experiment could be how many seeds or how much fertilizer is needed to get the preferred plant growth/production. Currently all the plants (although they are all different heights) are all very successful and all look healthy. Our Basil seeds have sprouted and started leaves. The spruces have continued to grow from seedlings and are now producing more and more leaves each day. |
