(1) What is Chemistry?Do you want to find out about..

What is plastic made of?

(1) WHAT IS CHEMISTRY GOOD FOR?Do you know about Silicon Valley?

Silicon Valley is a region in the southern part of the San Francisco Bay Area in Northern California that serves as a global center for high technology, innovation, and social media

(1) WHAT IS CHEMISTRY GOOD FOR?Do you know about Silicon Valley?

(1) WHAT IS CHEMISTRY GOOD FOR?But why Silicon Valley?

Silicon comes from Sand!And it is the material used to make computer chips

Silicon is a metalloid, atomic number fourteen with an atomic weight of twenty-eight.

It is known for its semiconductor properties.

(1) WHAT IS CHEMISTRY GOOD FOR?Other uses of Silicon

The uses for silicon are varied, silicone grease can be used to lubricate a Rubix cube in order make it spin fast enough for use in a “speed cubing” competition

silica gel packets are heavily relied upon to keep moisture out of packaging and silica is even used as a food additive.

(1) WHAT IS CHEMISTRY GOOD FOR?How does the soap remove oil stains from our hands?

OIL WATEREMULSIFIER

(2) Field and Careers of Chemistry

(3) Careers in Chemistry

You can work chemistry into any industrial, educational, scientific, or governmental field.

Mastery of chemistry is associated with excellent analytical and mathematical skills (Problem solving).

These skills are useful for any job!
