Science - ANS A process of using observations and experiments to draw evidence-based
conclusions. (a pathway by which we can come to discover and better understand our world)
Scientific thinking - ANS Self-correcting and based on experience and observations that are
rational, testable, and repeatable
Limits of science - ANS - Can be applied only to the observable and measurable natural world
- Cannot tell us what to do with the information it uncovers
- Provides no help as to what is morally or ethically right or wrong
- The objects of scientific study must be observable and quantifiable
What can't science do? - ANS - Speak to the existence of God or any supernatural event or
creature
- Distinguish or quantify "beauty" or lack thereof
- Answer all questions
Biology - ANS The study of living things
Biological literacy - ANS Ability to use the process of scientific inquiry to think creatively
about real-world issues in order to communicate those thoughts to others and integrate them
into your decision making

Step one of scientific thinking - ANS Make observations about the world around you
Step two of scientific thinking - ANS Formulate a testable (supported or rejected by
experiments or non-experimental studies) and falsifiable hypothesis (can be ruled out by data)
Step three of scientific thinking - ANS Prediction: propose a situation that will give a
particular outcome if your hypothesis is true but a different outcome if your hypothesis is not
true
Example: If the toaster does toast, then the hypothesis is supported —likely correct
If the toaster doesn't toast, then the hypothesis is not supported — likely incorrect
- What follows the "if" is the independent variable and what follows the "then" is the
dependent variable
Step four of scientific thinking - ANS Experimentation: an experiment is a repeatable
manipulation of one or more aspects of the natural world
Independent variable - ANS A variable that stands alone and isn't changed by the other
variables you are trying to measure
Dependent variable - ANS The outcome factor, the variable that responds or could
potentially respond to changes in the independent variable
Controlling variables - ANS - The most important feature of a good experiment
- The attempt to minimize any differences between a control group and experimental group
other than the treatment itself
Treatment in controlling variables - ANS Any experimental condition applied to individuals
