What is inferring?
100
This is the definition/description of a hypothesis.
What is a possible (testable!) answer to a scientific question?
100
This is the scientific law that explains what would happen if Mrs. Smith threw a softball into the air.
What is the law of gravity?
100
This is why scientists use models.
What is to help them understand theings that they cannot observe directly?
100
This is the process that breaks down rock and other substances.
What is weathering?
200
This is making a statement or a claim about what will happen in the future based on past experience or evidence.
What is predicting?
200
This is the variable you measure to gather results.
What is the dependent variable?
200
When doing an experiment, this is how many (minimum)trials you should do to make sure that you are getting accurate data.
What is at least 3?
200
A representation of a simple of complex object or purpose is this.
What is a model?
200
This occurs where bits of broken rock are laid down in new locations.
What is deposition?
300
This is the grouping together of items that are alike in some ways.
What is classifying?
300
In a controlled experiment, this is the variable that is exposed to the same conditions as the experimental group, except for the variable being tested.
What is the control variable?
300
This is the best way to represent data that compare the relationship between two variables.
What is a line graph?
300
This is what happens if a new observation does not support a scientific theory.
What is the theory may be revised or discarded?
300
This is the process by which bits of broken rock are carried away.
What is erosion?
400
This is the definition for inferring.
What is explaining or interpreting the things you observed based on reasoning from what you already know?
400
This is why the results of an experiment may not be able to answer your testable question.
What is because more than ONE variable was changed, or manipulated? You can change only ONE variable (independent) in a controlled experiment.
400
The metric system of measurement is used to do this.
What is collect numeric data?
400
This is a collection of facts open to new evidence and interpretations.
What is scientific knowledge?
400
This consist of small particles of rock or soil or the remains of plants and animals.
What is sediment?
500
These are the differences between qualitative and quantitative observations.
What is a quantitatative observation deals with numbers or amounts, but a qualitative observation deals with descriptions that cannot be expressed in numbers?
500
This is the variable that you change or manipulate in an experiment.
What is the independent variable?
500
This is the main purpose for keeping honest and accurate records during a scientific investigation.
What is so that they investigation can be repeated and get the same results?
500
This is why a theory might be discarded or revised.
What is NEW EVIDENCE or new interpretations?
500
This is the type of weathering that causes the mineral composition of rocks to change.
