Natural Selection Image Map

Activity 1

Orientation
This activity is designed to allow students to conduct an experiment to help understand whether global warming would raise the sea level by melting ice.
Materials
A glass of ice water
A paper towel

Fill a tall glass with ice. Set the glass on a dry paper towel. Now fill the glass completely to the top without spilling any water and without letting any water overflow.  The paper towel should be completely dry.

Make a prediction on what will happen when the ice melts. Will the glass overflow? This is a miniature test of the question of whether melting icebergs in the North Pole will raise the level of sea water along beaches and costal cities.
