What is science
What is the systematic study of natural events and conditions?
How does science affect people
What is the way we think and the way we live our lives?
The most trustworthy source is
What is journals of scientists?
Why do we use SI units
What is it allows other scientists to repeat another's experiment?
What is a model
What is something that shows the structure of an object, system, or concept?
What do you do first if you were a scientist (experiment or hypothesis)
What is hypothesis and then experiment?
What is the independent and dependent variable
What is the independent variable is what the scientist changes purposely to try to get different results and the dependent variable is what changes because of the independent variables change?
What helps us investigate information
What is tools and simulations?
What did measurements used to be based off of before it got changed
What is the body?
What is a stimulation
What is something that uses models to imitate the function, behavior, or process of whatever the model represents?
What is data
What is information gathered by observation or experiment that can be used in calculating or reasoning?
What is a controlled variable and give an example
What is something that stays the same in an experiment no matter how many times you test. ex- beaker if you want to see what type of water breaks alia-seltzer faster?
When a scientist comes up with an idea it must be... and why
What is testable and reproducible so scientist can test it multiple times to see if it is correct?
The base units for SI are
What is meter, kilogram, second, and kelvin?
What are models and simulations used for
What is to answer difficult questions and to represent complex systems, to test new ideas, and to make new predictions?
How are experiments and observations related
What is you make observations about the experiment to see if your hypothesis is correct?
What is the difference between law and theory
What is that law is why and what happened and a theory is an explanation of why something happened?
5 characteristics of science
What is careful, creative, curious, logical, and skeptical?
Turn 550,000,000,000,000 into scientific notation
What is 5x1014 ?
The different types of models are
What is Physical models (scale, and life-size), mathematical models, and conceptual models?
What is the difference by pseudoscience and empirical evidence
What is pseudoscience is not based off of real evidence and empirical evidence is real observations and measurements?
The steps of the scientific method
What is 1.define a problem 2. for hypothesis 3. plan investigation 4. identify variables 5. collect and organize data 6. analyze data 7. make conclusions?
How scientific methods are used... and why
What is they can either be used to test experiments in a field investigation (lets you have control over some things) or natural investigation (lets you test it in a natural environment)?
Why are accuracy AND precision are important
What is you need both because you need it to be accurate and accurate the whole time (precision) to prove that your hypothesis is correct?
How is each type of model used
What is...
Physical models: represents the physical structure of an object or system
Mathematical model: represents the way a system works or processes
Conceptual models: representation of how parts of a system are related or organized?
