Compare scientific law and scientific theory.

3. Scientific Law
Describes how things work, can be tested by repeated experiments
Allow scientist to predict
Does not explain how, can not change.

4. Scientific Theory Are always questioned
Explains an observation clearly and consistently.

Must be able to predict results from the theory
Can be replaced or changed when new discoveries are made.
New theories are often criticized.

5. DATA Qualitative: Data that uses words to describe the observation
When I let go of the pen it fell to the table
Quantitative: Data stated as a mathematical equation or numbers.
F = m a , 12 eggs
Math is the same in every language, used as a standard.

6. Models:
A representation of an object or event that can be studied to understand the real object or event.
Used for things that are too big, too small.
Can be drawing or scale models of things
Computer models: combines lots of data and calculations to make predictions.
