Question

Which activity would be an appropriate first step

when designing an experiment?
(1) reporting a conclusion based on multiple
experimental trials
(2) researching the problem, using information
from a variety of sources
(3) creating a data table to organize experimental
observations
(4) repeating the experiment with a different
hypothesis

Answer 1

The appropriate initial step when you design an experiment is number (2). It is doing research about the problem utilizing information from different reliable sources. Among all the choices, this is the first step that should be done because you have to know everything about the problem first before the other 3 steps are done.

Answer 2

2) Researching the problem using information from a variety of sources. When designing an experiment, it is important to know what one is trying to achieve. At this point, one can seek previous publications and internet sources to find out what is required for the experiment and the best way to create the set up.
