The Nature Of Science
The study of the natural world based on facts learned through experiments and observations.
What is the definition of science?
A __________can be answered by designing and conducting and experiment. (Must have independent and dependent variables)
What is a testable question?
A possible answer to a scientific question.
What is the definition of a hypothesis?
Scientists use ____________when they cannot experiment on the real thing
What is a model?
specializes in the history of Earth.
What is a geologist?
What you think is happening at the same time of the observation
What is Inference?
This graph shows you how things are changed over time
What is a line graph?
A scientific procedure to make a discovery, test a hypothesis, or demonstrate a known fact.
What is the definition of an experiment?
Repeating the experiment performed by someone else, another scientist.
What is replication?
studies elements, atoms, and molecules.
What is a chemist?
What type of experiment is typically done in nature?
Observational
Gathering information in small pieces to answer a larger question

What kind of graph do you make when your dependent variable is percentages or fractions/parts of a whole?
A Pie Graph
a measurement based on the number 10.
What is the SI metric system?
After making an observation, what you think is going to happen.
What is prediction?
Describes or state what happened. May be a mathematical formula.
What is a scientific law?

Liter (l)
What is the definition of a control variable?
the variable that remains the same throughout your experiment
What are the 6 steps of the scientific method in order?
What are:
Purpose or Ask a question
Do some background research on the topic
State your hypothesis or educated guess
Conduct your experiment
Analyze your data - what does it mean?
State your conclusions and SHARE!
Identify the IV, DV, CV?
How does the type of dirt (sand vs. potting soil) effect the growth of a plant?
What are:
IV: type of dirt
DV: growth of plant
CV: plant, location, tools used during experiment
States why something happened. Based on hypothesis, experiments or observations. Explains.
What is a scientific theory?
What is a hypothesis based on the testable question below:
How does fertilizer effect the growth of a plant?
What is
If I increase the amount of fertilizer, my plant will grow taller because it's receiving the nutrients needed for it to grow.
In a scientific experiment, what are we testing?
The relationship between an independent and dependent variable. Does the independent variable actually have an affect on the dependent variable?
