Items Needed:
* ice cubes or snow
Do
this activity over the kitchen or bathroom sink.
Take
an ice cube out of the freezer and place it in your hand. Make a fist
around the ice cube and hold on. See how long it takes before your hand
goes cold or numb. Is it painful? Can your hand still move?
Now imagine that you have just crashed through the ice. Remember that the river is made up of melted snow and ice. How long do you think you could survive in the water? Would your whole body go numb?
