Websites   http://www.census.gov/ipc/www/idb/ http://hdrstats.undp.org/ https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html   Helpful Instructions: Question 1a) -go to the first website -Click on data access -select a country -select 1950 -click submit   Question 1-bcd) -return to main page -look at the demographic indicators: Midyear populations   Question 3 -Look up  “growth rate” on the internet, may be more accurate if you use Population growth rate   Question 6 -click on populations pyramids in the tabs above the information, if nothing comes up for your country show me.   Question 7 -type in http://www.census.gov/cgi-bin/ipc/pcwe   Question 8 Go to the website: http://hdrstats.undp.org/ -click on country to find your country -look up your country: and look up the HDI value for your country and look across to the GDP per capita   Question 9 Go to the website: https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html -scroll down to find your country -scroll down to the “People” category -scroll down to the “economoy” category   Question 10 -scroll up to “background” information -you are also able to look at other websites to find other information -if you can’t find any information try to explain one of the examples we discussed yesterday in class

       Ionic compounds are made up of positive (Metal) and negative (nonmetal) ions. *Positively charged ions are called cations *Negatively charged ions are called anions The ions are present because the metal gives its valence electrons to the nonmetal making both of them stable now.     They conduct electricity o   THEY TRANSFER ELECTRONS   o   Table salt is NaCl    Read pages 188-189 Complete questions 1- 4 p 189
