5 Branches of Chemistry Unit 1. 1 Sept 9 th, 2010

Bellringer 4 min(Use a separate sheet of paper; place in Bellringer section) Ø Answer l the following in 3 -5 sentences: What in your world is better or easier because of Chemistry?

One More Procedure Issue…. Ø Bathroom pass distribution l l l You will have 3 per semester They may be used for a 4 minute bathroom break 10/10 rule applies (no passes first/last 10 min) You may use these as HOMEWORK passes starting 2 nd quarter If you use NONE of them, you may use them as E. C. points

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

With all the chemist abilities they will be able to figure this out!!!

WHAT WOULD THE (A) ORGANIC CHEMIST DO? Ø Organic Chemistry is the study of compounds that contain the element carbon. Carbon is the basis of ALL life. Carbon can be found almost everywhere but here a few examples of carbon based compounds: l Fuels such as petroleum, and propane l Almost all medicine l Food l Deoxyribonucleic acid (DNA) Ø The organic chemist would take a sample of dung and test it with a lab instrument to see if the animal was a vegetarian or carnivore based on the various degraded foods present in the feces.

WHAT WOULD THE (B) INORGANIC CHEMIST DO? Ø Inorganic chemistry is the study of compounds that are not made of carbon or only have one carbon atom within them. Most of what is NOT alive is studied by inorganic chemist. Examples include: l Rocks l The calcium make up in human bones l Most acids, bases, and salts l Natural gases (found on earth and in space) Ø The inorganic chemist would take a sample of dung and figure out if it is an acid (like vinegar, tomato juice, and acid rain) or a base (like Bleach, Ammonia, and Antacids) by dropping the sample into a p. H indicator liquid.

WHAT WOULD THE (C) PHYSICAL CHEMIST DO? Ø Chemistry that relies on a lot of physics and math to study the changes in energy that happen to matter. This area can deal with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change. Examples could include: l What happens to the H 2 O molecules (water) when it turns from ice to liquid? l Why nylon (pantyhose) has the ability to stretch? l Why plastics are flexible but strong at the same time? Ø The physical chemist might take the results that the organic chemist found and get more information about the degraded food. The physical chemist would not touch the feces!

WHAT WOULD THE (D) ANALYTICAL CHEMIST DO? Ø Chemistry that detects & identifies if a substance is present in a sample (qualitative analysis) and how much is there (quantitative analysis). This chemist is concerned with the COMPOSITION (what’s inside/what something is made of) of substances. An analytic chemist may do such things as: l Study a blood sample to see if poison is present (think CSI). l Determine if a white powder is cocaine or baking soda. l Test a sample of paint to see how much lead (poisonous to humans) is present. Ø The analytical chemist would take a sample of dung and calculate if the animal was drinking clean or polluted water based on the levels of pollution chemicals in the feces. This chemist would also tell you the quantities of everything that is in the dung (how much food, how much pollution, etc. ).

WHAT WOULD THE (E) BIOCHEMIST DO? Ø Chemistry that deals with chemical processes that take place inside living organisms. Biochemistry is closely related to organic chemistry because it studies the processes and compounds important to life. These studies may include: l The study of digestion, blood clotting, and what happens to blood when exposed to carbon monoxide (poisonous to humans) l The study of bugs l The study of cancer Ø A biochemist would take a sample of dung and test it to see if the animal was infected with any kinds of worms or other intestinal parasites. This chemist would also tell you how well the animal was digesting his food.

After the 5 types of scientist performed all their studies they concluded the dung came from…?

After the 5 types of scientist performed all their studies they concluded the dung came from……

Peer to Peer Instructions Find one person close to you Ø Designate one person as the READER and the other person as the RECORDER Ø Place a heading on one sheet of paper with BOTH names on it (if both names are not present you cannot receive credit) Ø Read the statements on the next slide and match them to the proper branch of chemistry Ø Next to each number, write the type of chemist that would do each task Ø
