General steps that scientists follow to solve problems.
A hypothesis must be _______.
A hypothesis must be _______.
Testable
How do you organize collected data?
How do you organize collected data?
Put it into a table or a chart.
What is a conclusion?
What is a conclusion?
A summary of what you have learned from the experiment
What’s the difference between scientific law and theory?
What’s the difference between scientific law and theory?
The law describes an observed pattern in nature and the theory explains why something is happening in nature. Laws cannot change. Theories can.
The scientific _______ can change and the scientific ______ can not change?
The scientific _______ can change and the scientific ______ can not change?
The scientific theory can change and the scientific law can not change.
Define Scientific Inquiry
Define Scientific Inquiry
Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather.
What is a scientific law?
What is a scientific law?
The scientific law describes an observed pattern in nature without attempting to explain it.
What is a scientific theory?
What is a scientific theory?
A scientific theory is a well tested explanation for a range of observations or experimental results.
What is a variable?
What is a variable?
Factors that change in an experiment
What is the difference between an independent and dependent variable?
What is the difference between an independent and dependent variable?
The independent variable is purposely changed and the dependent variable changes because of the independent variable
What is a controlled experiment?
What is a controlled experiment?
An experiment in which only one variable is manipulated at a time
What is Communicating?
What is Communicating?
The sharing of ideas and experimental findings with others through writing and speaking.
In order to have a controlled experiment the variables (aside from the independent variable) must be _____________
In order to have a controlled experiment the variables (aside from the independent variable) must be _____________
Exactly the same
Define an observation.
Define an observation.
Observing means using one or more of your senses to gather information.
What are 2 types of observations?
What are 2 types of observations?
Quantitative and Qualitative Observations
Define an inference.
Define an inference.
An interpretation based on observations and prior knowledge.
Define a prediction.
Define a prediction.
A prediction is a forecast on what will happen in the future based on past experience.
How do observations, inferences and predictions go together?
How do observations, inferences and predictions go together?
After you observe something, you can then make an inference on what you saw. Based on your observation and inference you can then make a prediction on what will happen.
What is data?
What is data?
The facts, figures, and other evidence gathered through observations
An experiment in which only one variable is manipulated at a time is called a _______
An experiment in which only one variable is manipulated at a time is called a _______
Controlled Experiment
What is a manipulated (independent) variable?
What is a manipulated (independent) variable?
A variable that is purposely changed
Is this statement an observation, inference or prediction? "The cat is ill"
Is this statement an observation, inference or prediction? "The cat is ill"
Inference: You cannot observe the cat being ill, you can observe the cat sleeping a lot or thowing up, but you would then infer that the cat is ill based on these observations.
An ______ is a statement that describes how to measure a particular variable or define a term.
An ______ is a statement that describes how to measure a particular variable or define a term.
An operational definition
