Conduct research: she can find what the cause of her distraction is.
test the design: she then tries to complete her homework without whatever thing she found in the first step.
Answer:
Systematic observation allows the understanding of each phase of a task, allowing the researcher to understand every thing that happens, generating a comprehensive and complete conclusion.
Explanation:
Systematic Observation is a method used to understand how a particular activity or task works. The researcher observes the stages of a process, the tools used, the difficulties that appear, the conversations and the results of the work. Systematic Observation is guided by a definite goal, one thing one wants to know about that activity. The observation is made over and over until there is sufficient evidence to assert such a thing.
Systematic Observation can be used to do Behavioral Mapping, Task Analysis, or Activity Analysis.
When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off. If enough of these expelled neutrons cause the nuclei of other U-235 atoms to split, releasing further neutrons, a fission 'chain reaction' can be achieved. When this happens over and over again, many millions of times, a very large amount of heat is produced from a relatively small amount of uranium.
It is this process, in effect "burning" uranium, which occurs in a nuclear reactor. The heat is used to make steam to produce electricity.
