The scientific procedure questions | form one Chemistry

In Chemistry, experiments test:
A. Data.
B. Problems.
C. Hypotheses.
D. Observation.

The second step in the scientific procedure is:
A. data collection and analysis
B. data interpretation
C. experimentation and observation
D. hypothesis formulation

The factors that affect the problem being investigated is refered as

1. dependent factor

2. variables
3. independent variables
4. conditions

Which of the following is the most correct statement about hypothesis?

1. a fundamental concept or theory
2. a possible explanation to the problem
3. an important statement of a research conclusion
4. a stage in data interpretation

1. Explain three factors which affect the problem being investigated.
2. Explain two areas where scientific procedure is applied.

Which decision should be made if the results of an experiment ​ do not support the stated  hypothesis?
A To use the results as an idea for further testing.
B To ignore the results and set a new experiment.
C To repeat the experiment in the same way.
D To identify a new problem.

With an example for each, give two fields in which the scientific procedure is applied.

Categorize the three factors (variables) which affect the problem being investigated during
scientific investigation.

Differentiate hypothesis from analysis.

Effective use of the four senses of observation is important before a chemist can make a  conclusion. With four points, show how the senses are used as tools of observation during
experimentation by giving one example for each.
