SIZE MATTERS BIG NUMBERS IN DAILY LIFE

OBJECTIVES FOR THIS UNIT YOU WILL READ AND INTERPRET DATA FROM CHARTS, TABLES, AND/OR GRAPHS, SPECIFICALLY WHAT “EXPONENTIAL” GROWTH MEANS AND WHAT IT LOOKS LIKE ON A GRAPH YOU WILL DEMONSTRATE KNOWLEDGE OF SCALE OF LARGE NUMBERS YOU WILL INCREASE YOUR KNOWLEDGE OF SCIENCE VOCABULARY RELATED TO MATH

LARGE NUMBERS IN DAILY LIFE WAREHOUSE ORDERS NATIONAL DEFICIT: AS OF 4/14, $492 BILLION, LOWEST SINCE NATIONAL DEBT: APPROX. $17, 000,000,000,000 (TRILLION) LARGE DISTANCES – FOR EXAMPLE, EARTH TO MOON COMPUTER MEMORY : BETWEEN 1980 AND 2000, HARD DISK SIZES INCREASED FROM ABOUT 10 MEGABYTES (MEGA = MILLION) TO OVER 100 GIGABYTES (GIGA = BILLION) EPIDEMICS ????

MATH IN THE NEWS – MATH VOCAB WHAT DO YOU KNOW ABOUT THE EBOLA VIRUS? IN JUST A MINUTE WE ARE GOING TO HEAR TO A 3 MINUTE NEWS CLIP AND LISTEN FOR SOME MATH/SCIENCE WORDS.

DON’T PANIC – BE INFORMED Don’t Panic! Ebola is spreading rapidly in parts of Africa because of poverty, poor sanitation, lack of access to medical care, and people’s superstition and lack of knowledge about how the disease spreads Ebola is not spread through casual contact, but most commonly through direct contact with the blood of an actively sick person or An infected corpse

LISTEN A FRIGHTENING CURVE: HOW FAST IS THE EBOLA OUTBREAK GROWING? WHEN YOU HEAR THE STORY, WRITE DOWN WHAT YOU THINK THE FOLLOWING WORDS MEAN Exponential A number that keeps doubling. On a graph it can grow slowly at first then form a steep curve. Computer model A computer program that is designed to show what might or what did happen in a situation. Forecast An educated prediction often based on computer models

THE WISE MAN AND THE RICE: EXPONENTIAL GROWTH THERE IS A STORY ABOUT A WISE MAN WHO WON A REWARD FROM A KING AND ONLY ASKED FOR GRAINS OF RICE ON A CHESS BOARD. HE ASKED FOR ONE GRAIN ON THE FIRST SQUARE, 2 ON THE SECOND, 4 ON THE THIRD, AND SO ON WITH EACH AMOUNT OF RICE DOUBLING IN THE NEXT SQUARE. BEFORE THE CHESS BOARD WAS EVEN FULL THE AMOUNT OF RICE COST MORE THAN THE KING HAD IN HIS ENTIRE TREASURY.
