Vocabulary
In an experiment you use multiple trials to get an accurate measurement, this is called...
Repetition
What are the steps of the scientific method?
question, research, hypothesis, experiment, analyze data, conclusion
REPLICATION OR REPETITION: After completing an experiment, you ask your friend to do the same experiment so you can check your results
Replication
What is the independent variable?
The variable that is being changed or manipulated by the scientist
What you use to record and display your data when looking for relationships among the variables.
What is a data table or graph?
After makings observations you begin to draw these conclusions.
What is an inference?
The type of data the scientists record from making observations based on measurements in science?
What is quantitative data?
Why is it important that all scientific experiments can be replicated?
To compare results
What is the dependent variable?
What is being measured or recorded, the data
After making observations and inferences you create this which is a possible explanation of your observations and can be tested.
What is a hypothesis?
The investigation and exploration of natural events that occur in the world around us.
What is science?
A representation of something in the natural world, typically too small or large to study up close.
What is a model?
"Do students like math or science better?" Is this a testable question, why or why not?
No, it is based on opinion
The variables that remain the same for all trials in an investigation so that the experiment can be VALID.
What are the constant variable?
If your hypothesis is not supported by the data, this is the next step in the process.
Form a new hypothesis
A well-supported explanation of the natural world (hint: explains WHY something happens).
What is theory?
DAILY DOUBLE: What happens to a theory when new information is discovered? Give an example of a theory that has changed due to new evidence.
The theory is changed based on the new discovery
Can a scientific theory become a scientific law?
No, they are two different things
Name the control to the following experiment. How does the amount of water effect the growth of a plant? You give three different plants 1 cup of water, 2 cups of water, and no water
What is no water?
When graphing, you put the dependent variable on this axis
What is the y axis?
Describes a basic principle of nature that always occurs under certain conditions (hint: Describes WHAT happens).
What is a law?
All scientific experiments require these two variables
Independent and dependent
Explain the difference between a scientific theory and scientific law
Theories explain how or why, laws describe what
DAILY DOUBLE: How does parachute size effect the rate of a falling object? Name the independent variable and dependent variable
What is the size of the parachute? What is the rate of a falling object?
When graphing, you put the independent variable on this axis
x axis
