| Explore | Outside of school we have learned that plants need sunlight, water, and carbon dioxide to live. In school we have learned about photosynthesis, the plant parts, and the plant cells. Does different water affect the plants growth? |
|---|---|
| Research Question | Will different types of water work better than other types of water? If so, how much better will it work and how much faster? We came up with the question because we had started out with using different liquids (milk, soda, ect.) but we heard everyone else talking about doing that too, but we liked the idea of different liquids. We then decided to try different types of water. A plant needs water to survive, and in the wild plants's water is rain water, so that is our controlled variable. |
| Predictions | We are imitating corn grown in field, our controlled variable is rain water. The salt water will probably grow the slowest, dyed might slow it and change how it turns out fully grown, tap will grow at a medium speed, rain also will grow at a medium speed. We think that pond water will work better because of all the nutrients in it. We think it will grow the fastest and strongest. |
| Experimental Design | 1. Our materials list --50 containers --Pond water --Salt water --Tap water --Dye --Rain water 2. Our plan is to conduct an experiment to see if different types of water affect the growth of corn. 3. We have 5 different types of water including the controlled variable. 4. They are pond water, tap water, rain water, salt water, and dyed tap water. 5. We will observe if the plant grows faster than the controlled plant. 6. For the controlled variable we keep the water given to a plant same amount of natural light, same temperature, and same amount of soil. 7. We will record our observations and data in our journal. |
