Day 136: How Big is 4.6 Billion? April 3, 2007

After defining the Geologic Timeline in class yesterday, today’s goal was to gain a better understanding of how large of a number 4.6 billion is.  Since that is the best estimate we have of the Earth’s age, we were attempting to quantify this number to gain a better appreciation for how old that is.  We began by calculating how long it would take to count to 4.6 billion.  We then estimated how large of a stack of paper we’d have if we printed a 10,000 stars on each page and wanted to represent 4.6 billion stars.  It’d be a TALL stack!

Tomorrow we will begin the Geologic Timeline lab activity that will continue tomorrow and into early next week.  There is no homework for this evening.
