Lesson 13

Library Research

After signing up today for your project be sure to continue to synthesize your information using your assignment sheet as your guide.

Next class, we will be taking up work on the histroy of the atomic theories that you are to complete for homework (worksheet fromt the beginning of class).

We will then be exploring the bohr-rutherford model of the atom and building atomic structures.

Then we will be looking to learn some simple word equations and how to count atoms in an equation.

Keep in mind the unit test is on October 15. Please use this website as a resource to post concerns, questions or comments under the "comment" section of the web page.

Cheers,
Mr. D

Andrew,

There is definitely an RDA for the element you are researching. Take the weekend to do some "investigative research" and let me know what you come up with.

ok i did some more research and i found this site
http://www.healthy.net/scr/article.asp?ID=2066

"There is no specific RDA for sulfur other than the amino acids of which they are part are needed to meet protein requirements. Our needs are usually easily met through diet. About 850 mg. are thought to be needed for basic turnover of sulfur in the body. There is not much information available on sulfur content of foods, nor are there supplements specifically for sulfur. I have found that it is not really a nutritional concern."

For that 850mg for a day? a month or for a year?
thx
