This variable is plotted on the Y axis
What is the dependent variable?
This is a process of observing, forming hypotheses, carrying out experiments, collecting data, and coming to conclusions based on this data
What is the scientific method?
The independent variable is plotted on this axis
What is 'the x axis?'
This term refers to the total number of individuals in an experiment
What is sample size?
This is the group of experimental subjects that is not receiving the treatment
What is the control group?
This is the experimental variable that the scientist thinks will respond or change based on some treatment

_______________ seeks to explain the occurrence of natural phenomena on earth
What is 'science?'
What are philosophy, history, literature, poetry, theology, spirituality, astrology, etc?
The pH scale is described as ____________________
What is logarithmic?
Explain the acronym 'DRYMIX'
What is 'dependent/response/y variable and manipulated/independent/x variable?'
Briefly explain why scientists can never be 100% certain of anything
What is 'because if scientists were 100% certain, then they could 'close the book' on that topic and assume they know everything there is to know or will EVER be to know - this is not true because we always leave open the possibility for a new piece of evidence or discovery to come to light that might change the way we think about something?'
This is what falsifiability means AND why it is critical for all scientific questions
What is 'it means that a question can be proven false if it is, in fact, not true; this is important because all questions asked using the scientific method must provide a way to be proven false if that is the case?'
A scientist wants to study the relationship between rainfall and the number of flood reports in upstate SC - identify the dependent and independent variables
What is 'dependent: number of flood reports, independent: amount of rainfall?'
List three examples of natural areas of study
What are biology, marine biology, psychology, geology, archaeology, oncology, virology, microbiology, astronomy, ecology, chemistry, etc?
Briefly define what we mean when we say 'natural' in the context of the scientific method
What is 'natural refers to any portion of the world that is part of tangible, objective reality. There is no room for opinion, bias, or personal agenda in the natural areas of study - only objective truth?'
List four criteria that every scientific question must meet
What are 1) predictable, 2) observable, 3) measurable, 4) falsifiable, 5) natural?
What is 'because the larger the sample size, the more confidence we can have in our results?'
Free hydrogen ions are specifically called ___________ because they are ____________ charged
What is 'cations because they are positively charged?'
In your own words, explain what would life would be life if we had stopped studying illness and disease during the 1400s:
What is 'we would have never discovered vaccines, bacteria, viruses, sanitation practices, antibiotics, and all modern medicine/life-saving healthcare?'
Briefly explain the different between a monomer and a polymer
What is 'a monomer is a single-unit substance and the smallest version of a biomolecule; a polymer is a multi-unit substance of a biomolecule and forms when two or more monomers bond together?'
Briefly explain why water is/is not an ion
What is 'water is NOT an ion because it is a neutral molecule?'
Briefly explain why scientists must continue to revisit questions that have already been asked
What is 'because the world changes - technology, diseases, society, and our planet are all constantly changing; therefore, the answer to the question 25 years ago may not still be the answer today?'
Briefly explain why scientists cannot always perform neat and controlled experiments in the lab:
What is 'because many scientific questions require going out into nature/the natural world and measuring the effects of things that have already happened - this does not usually allow for careful manipulation of independent variables and the use of control groups?'
In order to calculate the pH of a solution using traditional methods, that solution must be _______________
What is 'water based/aqueous?'
