Maggie's Plant Experiment In this exercise you will read the following scenario and identify the parts of the scientific method

in it. Maggle read that some plants grow better if the soil is acidic. She can't believe that a plant can grow when exposed to acid. Maggle decides to test if the plants she has will grow better when acld is added to the soil. She puts potting soll in two planting containers and transplants two of her geraniums that seem about the same size into the pots. She puts the pots in the same location so that they both get the same sunlight each day, are at the same temperature and she makes sure they get the same amount of water. However, Maggie puts a tablespoon of vinegar in the water she gives to one of the plants. She measures the growth of the plants every week for five weeks and records the results in a data table below: Height of Plants in Container with Height of Plants in Container without Week Vinegar Vinegar (cm) (cm) 10.0 10.0 2 12.4 11.5 3 14.8 13.0 18.0 15.7 5 21.4 17.8

Answer:

Here are the identified steps involved in the scientific method

Explanation:

The scientific method comprises a sequence of steps aimed at resolving a problem. The stages in the scientific method include:

1. Observations: In this investigation, Maggie noted that some plants thrive better in acidic soil. This observation led to the scientific inquiry: Do plants grow more effectively in acidic soil?

2. Formulating a hypothesis: A hypothesis is a testable proposition regarding an issue. In this scenario, Maggie's hypothesis states: IF acid is added to the soil, THEN plants will thrive better

3. Testing the hypothesis: The hypothesis is examined by conducting experiments. Here, Maggie places two geranium plants of identical size into two pots. She adds a tablespoon of vinegar to one pot allowing the other to grow normally without acid. The independent variable here is the vinegar, while the dependent variable is the growth of the plants. The vinegar group is the experimental set, while the one without is the control group. Constants in this experiment include sunlight, water amounts, location, etc.

4. Data analysis: The heights of both control and experimental plants were measured weekly over five weeks. The heights (in cm) of the vinegar plants over these weeks were: 10.0, 12.4, 14.8, 18.0, 21.4 while the heights in cm for the non-vinegar plants were: 10.0, 11.5, 13.0, 15.7, 17.8.

5. Conclusion: Based on the findings, the plants treated with vinegar outperformed the others each week except in week 1 when growth began. Consequently, the hypothesis for this experiment is ACCEPTED since the results support it.
