Description:

This drawing shows a tank containing 4 cups of cold tap water and a thermometer at one end. One cup of boiling water is being added to end of the tank opposite the thermometer. Above the tank, 3 mixing methods are shown: In the middle, the flat-side of the Popsicle stick is visible in one image and 2 arrows indicate it movement from side to side, across the width of the tank. The next middle image shows the Popsicle stick turned on edge and has arrows showing it moving back and forth, across the length of the tank. The end Popsicle stick above the 1-cup measuring cup again shows the flat edge with 2 arrows indicating movement across the width of the tank.
