Wow That's a Billion?

  1. 1. Here is a sample of what students can create for this Global Learning Project.<br />
  2. 2. Students can use whatever technology : Glogster, PowerPoint, video, etc. to tell about their billion that they created to share with other classes around the world.<br />
  3. 3. I wonder what a billion of .… would look like? <br />I am off to investigate!<br />
  4. 4. If you had a billion people lined up side by side, do you think they would be able to go all the way around the world? Do you think they would be able to go twice around the world? What about three times around the world? What is your prediction?<br />
  5. 5. Did you know…<br /><ul><li>If you took 1 billion people standing side by side, shoulder to shoulder, they would be able to go around the earth’s circumference 12 ½ times!</li></ul>WOW!<br />
  6. 6. Here is my process:<br />I measured 3 people and found that the distance end to end was about 59 inches.<br />Using proportions 3 𝑝𝑒𝑜𝑝𝑙𝑒59 𝑖𝑛𝑐h𝑒𝑠=1,000,000,000 𝑝𝑒𝑜𝑝𝑙𝑒𝑥 𝑖𝑛𝑐h𝑒𝑠<br />Solving by using cross-multiplication 1 billion people would be 19,666,666,666 inches<br />Since 1 foot is 12 inches, then 19,666,666,666 𝑖𝑛𝑐h𝑒𝑠12 𝑖𝑛𝑐h𝑒𝑠 = 1,638,888,888 ft.<br />The internet said the circumference of the earth is about 131,479,713.54 ft.<br />This means that 1,638,888,888 𝑓𝑡131,479,713 𝑓𝑡 = 12.5 times around the earth for 1 billion people<br /> <br />
  7. 7. My bedroom is 10ft X 10Ft x 9ft. This is a standard bedroom with high ceilings. Do you think a billion cheerios would fit in my room?<br />
  8. 8. Did you know…<br /><ul><li>I would need about 32.15 bedrooms to hold 1 billion cheerios.</li></ul>Gee<br />Willikers! <br />
  9. 9. Here’s the math:<br />I took a stack of cheerios and built a 1in x 1in x 1in cube. It took about 20 cheerios to make this cube. I had 5 cheerios in each of the 4 columns.<br />My room is 10ft x 10ftx9ft I decided to change this to inches….120 in. x 120in. X 108 in. This comes out to 1,555,200 cubic inches.<br />After cross-multiplying, I found that I would <br />need 50,000,000 ( 50 million) cubic space. <br />1 𝑐𝑢𝑏𝑒20 𝑐h𝑒𝑒𝑟𝑖𝑜𝑠  = 𝑥 𝑐𝑢𝑏𝑒𝑠1,000,000,000<br /> <br />Yet, I only have 1,555,200 cubic space in my room. How many rooms would I need? <br />This comes out to 32.15 bedrooms that I would need.<br />1 𝑟𝑜𝑜𝑚1,555,200 𝑖𝑛 𝑐𝑢𝑏𝑒𝑑 =𝑥 𝑏𝑒𝑑𝑟𝑜𝑜𝑚𝑠50,000,000<br /> <br />
