At the Oregon Math Leaders (OML) conference in August 2007, we attended Patty Sandoz's Pizza, Pop, and Problems (P^3) playshop and learned about Eager Eric. Great fun! We kept thinking about Eager Eric, and then wrote this unit.
We sent this email to the Oregon Teachers of Mathematics (OCTM) listserv in response to a posting about an interesting "real-life" math application. This investigation involved observing the growth of a milkshake-to-be as scoops of ice cream were plopped into the container destined to contain the milkshake.
We indulged in thought experiments about this activity and wrote the stuff you find here.
We sent email to students in Professor Richard Zimmer's Mars Society course at Sonoma State University, Fall 2003. One of the students had been assigned the task of measuring the heights of tall objects on the SSU campus. We suggested ways to measure the height of the tall object:
45-45-90 Degree Triangle Method
The clinometer method
The Defy Gravity, or Fly-on-the-Wall Method
The Defy, then Use Gravity Method
The What Goes Up Must Come Down Method
The Hot-Air or Helium Balloon Method
The Kite Method
The Statistical Survey Method
