Final answer:
The primary goal of a chemistry project that is both not difficult and unique is likely B) to investigate chemical reactions in everyday life, linking chemistry principles to daily experiences and demonstrating the relevance of chemical substances and processes in various aspects of life.
Step-by-step explanation:
The primary goal of a chemistry project that is not difficult and unique could encompass various aspects. However, based on the provided information, for a chemistry project to be engaging and also provide educational value, option B) To investigate chemical reactions in everyday life seems most appropriate. This allows students to connect chemistry principles with daily experiences, thereby enhancing understanding and interest in the subject. For instance, exploring the chemical processes involved in cooking or the reactions happening when cleaning with different substances can make chemistry relevant and intriguing. Chemistry projects can also focus on the practical applications of the subject in different fields. Examples include examining the chemistry behind forensics in law or the development of new materials in engineering. Thus, the goal of such a project is often to showcase how chemical substances and processes are integral to various aspects of our lives and the environment.
