Unit 1 - Nature of Science Study Guide

Scientific inquiry involves asking questions, conducting experiments, and analyzing data to gain knowledge.

​

​Scientific Inquiry

​Scientific Notation is used to convert very large or very small numbers. Look at the exponents to see if they are positive or negative numbers. This will inform on which way the decimal is moving.
Positive = Right Negative = Left

Developing Models

​Making the Unseen ----Seen !

When modeling, you must use components to represent the forces in a system.

Remember to make the unseen forces seen and use simple boxes or circles with arrows to show relationships.
