1. “That Sinking Feeling” Day 1

2. The Crow and the Pitcher adapted from “Aesop’s Fables” Once there was a terribly thirsty crow. She had not had a drink of water in days and knew that she would soon perish if she didn’t find water. Suddenly, to her delight, she spotted a pitcher setting on a table beside a pebbled path. Thrilled by the discovery, the crow flew to the table. When the crow reached the pitcher, she discovered to her grief that the water level was too low and the neck of the pitcher was too narrow. No matter how hard the crow tried to squeeze her head into the pitcher, she could not reach the water with her beak.

3. So, the crow tried to overturn the pitcher, hoping that the water would spill and then she could drink it. However, no matter how hard she tried, the pitcher was too heavy for the crow to move. Just as the crow was about to give up, she noticed the pebbles on the ground. An idea suddenly came to her. She picked up the pebbles one by one and dropped them into the pitcher. Each time she dropped a pebble into the pitcher, the water level would rise. Eventually, the water level was high enough for the crow to drink the water and save her life.

4. If you remember, buoyancy is the ability of an object to float or rise in a liquid or gas. How was the crow able to cause the water to rise so that she could get a drink? Now lets watch a short piece from a video that describes what buoyancy is- Lets watch the following video on buoyancy: http://dsc.discovery.com/videos/mythbusters -lets-talk-buoyancy.html http://dsc.discovery.com/videos/mythbusters -lets-talk-buoyancy.html
