Science Class on Friday November 5th, 2010

During today’s class, we took notes. Before we begun taking notes, Ms. D checked if we did our homework, which was filling out and completing the chart on carbohydrates, lipids, proteins, and water, and to finish reading pages 25-30 if we didn’t finish in class. Then, we all took out our notebooks and we began discussing what we read and what we wrote in our charts. We reviewed the periodic table of elements, we reviewed elements, and we took notes on what organic and inorganic meant, and the chart we completed, and we discussed and learned what a compound is. The notes were the following:

Elements = the basic substance of everything - can be made smaller

- 118 on the periodic table of elements

- 117 definite ones

- Block 117 doesn’t exist

If the letters in a block are written in:

Red = gas

Blue = liquid

Black = solid

White with black outline = human made solid

Organic- alive, living; carbon(C) based

Inorganic- not living; not carbon (C) based

Compound = molecules; two or more elements combined chemically; in order to separate I must add NRG.

Enzymes = speed up chemical rxn in body

We also added another compound to the chart which was nucleic acids, but we didn’t get to it during class. The chart had this information (I wasn't able to add a chart. So I wrote it out. Sorry):

Compounds:

Carbohydrates (Sugar and starch)- (4cal/g)

Lipids (Fat)- (9cal/g)

Proteins- (4cal/g)

Water (H2O)

Elements:

Carbohydrates= Carbon, Hydrogen, Oxygen

Lipids= Carbon, Hydrogen, Oxygen

Proteins= Carbon, Hydrogen, Oxygen, Nitrogen and sometimes Sulfur

Water= Oxygen, Hydrogen

Functions:

Carbohydrates= Provider of NRG

Lipids= Stores, produces NRG; similar to carbohydrates but contains even more NRG so it is harder to break down

Proteins= Also known as enzymes; make up organelles, help digest, form cell membranes/cell parts

Water= Makes up 2/3 of a humans body; helps cells keep their shape and size; keep cells from changing temp. too quickly; help chemical rxn

That is what we did in class on Friday. At the end of class we got homework to bring 4 nutrition labels (including carbohydrates, lipids, and proteins). We also have to read pgs. 30-37 in our textbooks, and we have to watch the link, on youtube, that Ms. D posted on Moodle!

Also, don't forget to water your pansy plants and water them!!!
