Question

For this assignment you must use your knowledge of the scientific method to design your own experiment. The first step of the scientific method is observation. Answer the questions below about how you would design your scientific experiment. Lab 1: Using The Scientific Method Worksheet At A Local Town Meeting, One Of Your Neighbors ...

At a local town meeting, one of your neighbors complains that a nearby residence is killing his flowers because of the chemicals he uses to wash his cars. He claims that the soap runs into a stream that flows very close to his flower beds. As an inquiring student of science, you wonder whether soap can truly affect flower growth. Based on the observation given to you, use the following questions to explain how you would set up your experiment and analyze your results.

1. State your hypothesis. Remember that a hypothesis must be specific and testable. For example, stating that detergents are bad is not a good hypothesis (“Bad” is a generic term, it would be better to use a metric that is measurable).

2. Explain how you would set up your control and treatment groups. What would be the same between the groups and what would be different? What species would you use for each group and how many plants total would you use?

3. How would you collect your data for your experiment? What tools and units of measurement would you use? How often would you collect data and would you use the same methodology for both your treatment and control groups? Be specific in your answers. In every experiment, there are some unintentional differences between the control and treatment groups. These are called sources of error. If these sources of error can be corrected we call them avoidable sources of error. An example of an avoidable source of error may be the amount of water provided to the plant. We can avoid this error by watering the plants in each group, the same amount at the same time of the day.

4. List some possible sources of avoidable and unavoidable error in your fertilizer experiment that were provided to you as examples.

5.. Explain the difference between a theory and a hypothesis.

6. Explain the difference between the ‘everyday’ use of the word theory and the definition of a scientific theory.

7. Why is it important to educate people on the true definition of “theory”?

Answer 1

Answer 5:- Hypothesis is known to be suggested explanation of observable phenomena which implies to explain the specificity of an observable things or a particular phenomena or we can say that a prediction of an observable phenomena which can be able to run under hypothetical condition. While theory is known to be well defined characteristics or observed phenomena with proven factor which can explain the fact about phenomena.

Answer 7:- Yes it is important to educate the people regarding the true definition of theory.. As per the science, theory explains with well defined manner which complete the research regarding the observed phenomena and try to explain where people can act on particular object with knowledge and it help to understand regarding its flaws and good things.
