In the Textbook Scavenger Hunt we have seen several interesting examples of Physics, but what is Physics?
Asked class.

Physics is an activity to search for RULES that EXPLAIN. SIMPLIFY and PREDICT the way nature works. Physics is about finding patterns and making predictions. Science is about finding relationships.

Science arose when humans found patterns in nature and were able to make predictions.

You can memorize a lot of data, or you can find relationships and rules.
Play : YOU CAN'T SAY THE RULE
If you uncover the rule you feel really good. If you can't, sometimes it can be frustrating.
