Question

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s 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 B- what is the students scientific question?Part C- What are 2 possible hypothesis for the students experiment?Part D- Choose 1 hypothesis and make a prediction Part E- how did you conduct your investigation explain your dependent and independent variables Part F- How does the design of your experiment control the outside factors that may affect the results?

Answer 1

.PART B

Student´s scientific question:

Do tomato plants grow faster with the application of a natural fertilizer compared to those with an artificial fertilizer?

PART C

Hypotheses (you can write others)

1- Natural fertilizer is more efficient than artificial fertilizer to make plants grow faster and taller.

2- Plants grow faster and taller with the natural fertilizer rather than without it.

PART D
