Review Scientific Method
Independent Variable? Dependent Variable? Control?
![Page 14: The Nature of Science. ACT Opener Keep the opener sheet with you for two weeks Write the question and answer it Which statement is always true for](https://reader035.vdocuments.mx/reader035/viewer/2022062306/5a4d1af17f8b9ab05997e36b/html5/thumbnails/14.jpg)
Notes Variable- a factor being tested
Two types Independent variable- the one you change Dependent variable- the one that changes
on its own control- any factor that remains the
same Great experiments have lots of controls

Notes Hypothesis-
Educated guess/proposed solution What makes a good one?
Branches of Physical Science Chemistry- the study of what substances
are made of and how they change Physics- the study of forms and energy and
laws of motion
