vocabulary
The systematic study of natural events and conditions.
What is science?
what is a model
What is a representation of how an object or process allow scientist to study something in greater detail?
What is a measurment
What is a description that includes a number and unit?
what are the base units for SI units
What is meter(m), kilogram(kg), second(s), kelvin(K)?
What is a stimulation
What is to use models to imitate the function, behavior, or process of what the model represents.
What is the difference between pseudoscience and empirical evidence
what is pseudoscience is not based on real evidence and empirical evidence.
explain empirical evidence
What is all of the measurments and data a scientist collects to support a scientific explanation.
Explain scientific notation
What is scientific notation is a short way or representing small/large numbers?
how are large/small measurments easy to deal with
What is scientific notation or prefixes?
what is a physical model.
What is models that represent the physical structure of an object or system?
what do you do first, make a hypothesis or collect data.
What is hypothesis?
Why are models helpful to scientists
what is they help scientist study something in a bigger/smaller version of the real object that is hard to study. It also makes it cheaper and easier.
What does science affect
What is the way we think and the way we live our lives?
what are tools used for in science
What is to preform expirements and make observations and measurments that regular senses cant?
How are expirements and observations related
What is after you make an expirement you make observations to see if your expirement supports your hypothesis?
What is the difference between accuracy and precision
What is accuracy is how close a measurement is to the actual quantity measured and precision is the exactness of a measurement?
When a scientists thinks of an idea it must be... and why
What is testable and reproducable so a scientist can re-check their work or so other scientist can see if it is correct or not.
convert 660,000,000,000 into scientific notation
6x1011
What is a mathematical model and what can you use to write this
What is a model that uses different forms of data to represent a way the system or process works. you can use a graph to write this?
The difference between an independent variable and dependent variable
What is independent variable is the variable that is purposely changes and the dependent variable is what is changed as a result?
what is the difference between law and theory
What is law is a description of why or how something happens and theory is an explanation of what happened?
What are five characteristics of all scientists
What is curious, careful, creative, logical, and skeptical?
What are the controlled variables and give an example of a situation
What is the thing in an expirement that always stays the same no matter how many times you test it. ex- you see what type of water will dissolve alka-seltzer faster, the controlled variable would be the beaker that you use because a different one might have different measurements.
What can you use to represent complex systems and to answer difficult questions.
What is models and simulations?
