A2.5- Our Chemical Society

introduction

Chemistry is everywhere!

Read the following website to learn about a handful of examples of Chemistry in our everyday lives.

Have you ever wondered why chemistry is so important? Why do we study chemistry? We all are made of chemicals and everything around us is made of chemicals. Everything we hear, see, smell, taste, and touch involves chemistry and chemicals (matter).

How can Chemicals negatively affect our society?

Explore the following videos & websites to see some examples that illustrate the negative impact chemicals can have.

How pollution is changing the ocean's chemistryAs we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk she takes us for a dive into an oceanographer's world. Learn more about how the "evil twin of climate change" is impacting the ocean -- and the life that depends on it.

Early forensics and crime-solving chemists - Deborah Blum In a CSI age, we take forensic science for granted. New York did not have a medical examiner or forensic toxicologist until 1918, whose eventual arrival changed the landscape of crime investigation forever. At TEDYouth 2012, Deborah Blum prompts the audience to solve crimes with chemistry.

Impact of Chlorofluorocarbons (CFCs) on the ozone layer:

It's a strange thing to think about, but have you ever wondered what would happen if the ozone layer suddenly wasn't there? Here's a hint: Getting a bad sunburn would be the least of your problems.

What if the ozone layer disappeared?
