An empirical scientific question is one that focuses on things, creatures, or occurrences in our immediate environment. By examining quantifiable data and supporting evidence, it can be resolved by experimentation, observation, or other data collection methods.
These questions are appropriate scientific questions and can be tested using the scientific method:
a) The color of Handragea flowers can be studied by growing it in different soils with different pH values and the result can be noted.
b) The properties of soil affecting color of flowers can be studied by growing the flowers in different types of soils like clay, sand, nutrient rich, nutrient deficient, silt, etc.
e) If the grass requires fertilizer one set of grass can be grown without fertilizer while one set can be grown with fertilizer to check the query.
There are limitations to the scientific process. Only quantitative data from observable, quantifiable, and repeatable experiments can it provide objective answers to questions. It is unable to respond to introspective queries based on qualitative judgments or beliefs hence, other options will be incorrect.
Hence, The following questions are considered appropriate scientific questions that can be tested using the scientific method.
a. Does the pH of the soil affect the color of hydrangea flowers?
b. What properties of the soil influence the color of hydrangea flowers?
e. Does grass require fertilizer in order to grow?
