Match it! Select the correct answer from the pull down...Good luck!

This is a a testable possible explanation of scientific observation.

If a model has this we say it helps the scientist explain and communicate observations.

This provide the purpose for doing science, and focuses the investigation

This is an ongoing, orderly, cyclical approach used to investigate the world.

In a controlled experiment, the scientist changes one variable (the independent variable) and observes the changes in a second (_______) variable.

When a scientist uses his senses, a scientist collects information about the world we call this what?

If a model works well and makes accurate predictions, then scientists will ______ it.
