5 chemists from each of the 5 branches of 5 chemists from each of the 5 branches of chemistry are out hiking the Appalachian chemistry are out hiking the Appalachian trail on a cold day. They come upon some trail on a cold day. They come upon some fresh, steaming pile of dung…..GROSS!!! fresh, steaming pile of dung…..GROSS!!! Did it come from a rabbit? A deer? A Did it come from a rabbit? A deer? A bear?! Or worse… a human being?!?!bear?! Or worse… a human being?!?!

WHAT WOULD THE (A) ORGANIC CHEMIST DO?WHAT WOULD THE (A) ORGANIC CHEMIST DO?

Organic Chemistry is the study of Organic Chemistry is the study of compoundscompounds that contain that contain the the element carbonelement carbon. Carbon is the basis of ALL life. Carbon . Carbon is the basis of ALL life. Carbon can be found almost everywhere but here are a few can be found almost everywhere but here are a few examples of carbon based compounds:examples of carbon based compounds: Fuels such as petroleum, and propaneFuels such as petroleum, and propane Almost all medicineAlmost all medicine FoodFood Deoxyribonucleic acid (DNA)Deoxyribonucleic acid (DNA)

WHAT WOULD THE (B) INORGANIC CHEMIST DO?WHAT WOULD THE (B) INORGANIC CHEMIST DO?

Inorganic chemistry is the study of Inorganic chemistry is the study of compoundscompounds that are that are not made of carbon or only have one carbon atom within not made of carbon or only have one carbon atom within them. Most of what is NOT alive is studied by inorganic them. Most of what is NOT alive is studied by inorganic chemist. Examples include:chemist. Examples include: RocksRocks The calcium make up in human bonesThe calcium make up in human bones Most acids, bases, and saltsMost acids, bases, and salts Natural gases (found on earth and in space)Natural gases (found on earth and in space)

The inorganic chemist would take a sample of dung and The inorganic chemist would take a sample of dung and figure out if it is an acid (like vinegar, tomato juice, and figure out if it is an acid (like vinegar, tomato juice, and acid rain) or a base (like Bleach, Ammonia, and acid rain) or a base (like Bleach, Ammonia, and Antacids) by dropping the sample into a pH indicator Antacids) by dropping the sample into a pH indicator liquid.liquid.

WHAT WOULD THE (C) PHYSICAL CHEMIST DO?WHAT WOULD THE (C) PHYSICAL CHEMIST DO?

Chemistry that relies on a lot of physics and math to Chemistry that relies on a lot of physics and math to study the changes in energy that happen to matter. This study the changes in energy that happen to matter. This area can deal with the mechanism, the rate, and the area can deal with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a energy transfer that occurs when matter undergoes a change. Examples could include:change. Examples could include: What happens to the H2O molecules (water) when it What happens to the H2O molecules (water) when it

The physical chemist might take the results that the The physical chemist might take the results that the organic chemist found and get more information about organic chemist found and get more information about the degraded food. The physical chemist would not the degraded food. The physical chemist would not touch the fecestouch the feces!!

WHAT WOULD THE (D) ANALYTICAL CHEMIST DO?WHAT WOULD THE (D) ANALYTICAL CHEMIST DO?

Chemistry that detects & identifies if a substance is present in a Chemistry that detects & identifies if a substance is present in a sample (sample (qualitativequalitative analysis analysis) and ) and how muchhow much is there ( is there (quantitative quantitative analysisanalysis). This chemist is concerned with the ). This chemist is concerned with the COMPOSITION COMPOSITION (what’s inside/what something is made of) of substances. An (what’s inside/what something is made of) of substances. An analytic chemist may do such things as:analytic chemist may do such things as:

Determine if a white powder is cocaine or baking soda.Determine if a white powder is cocaine or baking soda. Test a sample of paint to see Test a sample of paint to see how muchhow much lead (poisonous to lead (poisonous to

humans) is present.humans) is present.

The analytical chemist would take a sample of dung and The analytical chemist would take a sample of dung and

calculate if the animal was drinking clean or polluted water based calculate if the animal was drinking clean or polluted water based on the levels of pollution chemicals in the feces. This chemist on the levels of pollution chemicals in the feces. This chemist would also tell you the quantities of everything that is in the dung would also tell you the quantities of everything that is in the dung (how much food, how much pollution, etc.).(how much food, how much pollution, etc.).

WHAT WOULD THE (E) BIOCHEMIST DO?WHAT WOULD THE (E) BIOCHEMIST DO?

Chemistry that deals with chemical processes that take place Chemistry that deals with chemical processes that take place inside living organismsinside living organisms. Biochemistry is closely related to . Biochemistry is closely related to organic chemistry because it studies the processes and organic chemistry because it studies the processes and compounds important to life. These studies may include:compounds important to life. These studies may include: The study of digestion, blood clotting, and what happens The study of digestion, blood clotting, and what happens
