Doing Science

Steps in doing science

Ask a question

Look it up

Frame a hypothesis

Design experiment to test hypothesis

Carry out experiment

Draw conclusion

It is easier to test one hypothesis at a time

Make operational definitions

Control variables

Hypotheses must be testable

It is not a test if you cannot fail it

We don't prove things in science because we cannot test all possibilities

Science relies on samples and sampling

Everything in science is tentative
