Experiment 1: floating ice for this experiment, you will need a permanent marker, a translucent plastic cup, water, and ice. place a few ice cubes in the cup, and add water until the ice cubes float (that is, they don’t touch the bottom). mark the water level on the outside of the cup with the marker, and label this mark so that later you will know it was the initial water level. as the ice melts, what do you expect to happen to the water level in the cup? html editor keyboard shortcuts
