Comment: The student relates the choice of topic to the global topic of increased hand sanitizer usage and describes their personal interest in the effects of ethanol on cells

Comment: The process of researching the topic, designing the method, and a justification of the variables is present and serves as evidence for the student's personal input in the study

Comment: At the end of the introduction, the student should state the aim of this experiment. For example, "In this paper, I am going to examine how ethanol affects the cell membrane permability in...". This will help the reader understand what was done in this experiment

Comment: The background information section is clear and well-organized, with each paragraph explaining a different concept. All ideas needed for understanding the experiment are concisely explained - the characteristics of a beetroot cell and the pigments it contains, the mechanism of membrane disruption by ethanol, and the method of colorimetry used to measure the changes in this experiment

Comment: The biology of beetroot cells, as well as the processes behind membrane disruption by ethanol, are clearly explained using the correct and not overcomplicated subject-specific terminology

Comment: The biology of beetroot cells, as well as the processes behind membrane disruption by ethanol, are clearly explained using the correct and not overcomplicated subject-specific terminology

Comment: The biology of beetroot cells, as well as the processes behind membrane disruption by ethanol, are clearly explained using the correct and not overcomplicated subject-specific terminology

Comment: The student correctly identifies the independent (concentration of ethanol solution) and dependent (absorbance of solution after treatment) variables to pursue the research question

Comment: The student correctly identifies the independent (concentration of ethanol solution) and dependent (absorbance of solution after treatment) variables to pursue the research question

Comment: The student correctly lists the variables that have to be controlled or maintained constant for the results to be valid
