A good scientist is like a detective.

What other ways can you think of to check things out?

You could look for footprints or fingerprints.

You could ask an expert for help.

You could look at photographs.

You could listen to recordings.

Can you think of other ways to CHECK IT OUT?

Another rule of science is this:

If you check it out once,

you should be able to check it out again.

If you do a test or experiment,

you should be able to repeat it.

If you can't repeat the test, then there is

no way to be really sure if it is true or false.
