4
What is the last step in the scientific method.
Organize your data
State your conclusion
Test the hypothesis
Research your problem
5
A hypothesis has not been supported, therefore
Valuable information may have still been gained
There was no point doing the experiment
A new hypothesis must be tested

Research
Problem or question
7
What is the measured variable?
Controlled
Uncontrolled
Independent
Dependent
8
An experiment will be more reliable if
Appropriate equipment is used to collect data
Several variables are tested
A narrow set of samples are analysed
Many trials are undertaken
9
At the end of an experiment, the hypothesis is
Proven
Supported
Proven or disproven
Supported or not supported
10
Which is an appropriate hypothesis?

Hungry cats eat more rats
Sick rats aren't fast enough to avoid most hungry cats
Why do hungry cats eat more rats?

12
Research from various sources relevant to the proposed experiment.
Helps in the formulation of the conclusion
Is background information
Allows a method to be formulated
Will come after determining your hypothesis
