Background:

From 1849 through most of the 1850s, San Francisco was one of the most rip-roaring cities on Earth. Each day San Francisco built an average of 30 new houses and witnessed two murders and one fire. Its young, heavily armed, largely male populace drank at more than 500 bars and placed bets at 1,000 gambling dens. Eggs went for six dollars a dozen and landlords collected a mother lode of rentals for canvas shanties, abandoned ship's hulls and rooms in tinderbox houses. Fed on a diet of gold from the Sierra mines, San Francisco burgeoned into a major seaport in one year, bringing a wealth of both population and cargo that is still evident today. 

Activity #1 - Procedure:

1. Students develop a three-part KWL chart to record: K=What We Know prior to studying a topic; what they want to know (W=What We Want to Find Out); and what they ultimately have learned (L=What We Have Learned). Ask students, Why did San Francisco grow so quickly during the Gold Rush? Write this information in the first column of the class chart. Distribute Post-it Notes or something similar, and ask students what they want to learn about why San Francisco exploded. Stick these on the middle part of the chart (W), and move Post-its to the K side as students demonstrate new knowledge. 

2. Display population-growth chart on overhead or chalkboard: 
  Year
1848
1849
1850
1869
1995
  Population*
1,000
1,500
25,000
50,000
759,000

 *Population numbers are approximate because historical references vary.

3. Ask students, in pairs or groups, to make a time line with the year and population written on the bottom, and to predict (using words or pictures) what they think could have happened to cause the population to vary. (For example, in 1849 many of the people living in San Francisco left to go to the gold fields.)
