Question

using the scientific method this activity will help you meet this educational goal: you will plan an investigation using the scientific method and answer the proposed questions. directions read the instructions for this self - checked activity. type in your response to each question, and check your answers at the end of the activity. write a brief evaluation of your work. activity many farmers and gardeners compost their plant and animal waste. the living material naturally decays in compost bins forming a dirt - like substance thats rich in nutrients. the next season, farmers use this substance as a natural fertilizer for their crops. a biology student has grown tomato plants for several years. until now, he used an artificial fertilizer formulated for tomato plants. this fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. the student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. part a what are the students observations and inferences before he starts his investigation?

Explanation:

Observations: Many farmers and gardeners use compost as fertilizer. Artificial fertilizer made tomato plants grow faster and taller than unfertilized soil. Inferences: Natural compost might make tomato plants grow faster and taller than artificial fertilizer.

Answer:

Observations: Many farmers and gardeners compost waste; artificial fertilizer made tomato plants grow faster/taller than in un - fertilized soil. Inferences: Natural compost may cause tomato plants to grow faster and taller than artificial fertilizer.
