Andrew walks through his garden and observes that the shapes of dewdrops are not always the same. suppose he wants to investigate using the scientific method. which questions are testable questions that he can ask to look into the reasons for the different shapes?
a- does the shape of the dewdrop depend on the temperature of the surface?
b- which dewdrop seems to have the most unusual shape?
c- is the material of the surface responsible for the shape of the dewdrop?
d- which shape of dewdrop is the most pleasing to the observer?
e- does the shape of the dewdrop depend on the moisture in the atmosphere?
options a,c and e
A scientific method is the one which is independent of the person taking the measurements. Hence, a method which includes a scientific instrument/experiment, systematic observation, measurement, testing etc and is independent of personal feelings or opinions is known as a scientific method.
The measurement of temperature, testing of the material of surface, and moisture content in the atmosphere are testable questions and part of scientific method to find the reasons of different shapes of dewdrops. whether the different shapes are formed due to change in temperature, surface or moisture content in the atmosphere or not? The result of this measurement would not depend on the scientist doing the experiment. Scientific instruments would be used which would give the same reading. But the result of the observation of most unusual shape and pleasing shape of drop is purely dependent on one observer. It cannot be generalized reason. Hence, b and d are not testable questions.
The answers are as follows
Does the shape of the dewdrop depend on the temperature of the surface?
Is the material of the surface responsible for the shape of the dewdrop?
Does the shape of the dewdrop depend on the moisture in the atmosphere?
The other two answers are purely based on opinion, and does not actually effect the shape of the dewdrop in any way.
Using specific answers
Being specific to gather precise and accurate answers, and It gives you a question that is not vague or hard to answer. "Ask questions like, does the shape of dew drops change in different areas", or "significance of different sized dew drops". These questions are more specific than, "whats up with dew drops", or just searching "dew drops".
yes some dewdrops are same in size .please mark me the brainlest
