Why is science important today?

Science leads to discovery, but also provides a healthy skepticism

Page 5: Physical Science Studies NS 3310 Dr. Hoge. Chapter 1 – Why Study Science?  We live in a technological society brought about by scientific inquiry.

Future Shock The World Is Flat

Shift Happens

The U.S. Needs New Workforce

Particularly from Underserved Communities

And, It’s All Up to You

What is science? M&M Statistics:

we are going to determine if the Mars company is telling the truth when they claim that there are fixed percentages of each color in each bag of M&Ms.

I’m skeptical
