Question

42 categorization 1 point sophia, a college student, has recently started using a new type of organic fertilizer on her garden plants. shes heard from friends that organic fertilizers make plants grow faster and healthier than synthetic ones, so she wonders if this is true. she thinks that using organic fertilizer will lead to faster growth compared to using synthetic fertilizer. to test her hypothesis, sophia sets up an experiment with two groups of identical plants. one group will receive organic fertilizer, and the other will get synthetic fertilizer. both groups are given the same amount of water and are placed in similar sunlight conditions. sophia measures the height of the plants and notes their general health at the beginning of the experiment, then plans to track their growth for four weeks. after four weeks, sophia measures the plants again. to her surprise, the plants that received the organic fertilizer have grown only a little, while the plants that received the synthetic fertilizer have grown significantly taller and have thicker, healthier leaves. the organic fertilizer did not lead to faster or healthier growth compared to the synthetic one. she decides that while organic fertilizers may have other benefits, in this case, the synthetic fertilizer was more effective for promoting growth. sophia plans to research other factors that could contribute to plant growth, like soil composition or different types of organic fertilizers. observation no answers chosen hypothesis no answers chosen independent variable no answers chosen dependent variable no answers chosen control variable no answers chosen accept or reject hypothesis? no answers chosen theory no answers chosen possible answers plants with organic fertilizer will grow faster than those with synthetic fertilizer. amount of sunlight type of fertilizer reject hypothesis growth of the plant accept hypothesis amount of water

Explanation:

Observation: Sophia noticed plants with different fertilizers grew differently.
Hypothesis: Plants with organic fertilizer will grow faster than those with synthetic fertilizer.
Independent Variable: Type of fertilizer.
Dependent Variable: Growth of the plant.
Control Variable: Amount of water, amount of sunlight.
Accept or Reject Hypothesis?: Reject Hypothesis.
Theory: Not applicable in this simple experiment context.
