Our favorite experiment this week was .... the fire!! Our key word this week was DENSITY. Lighting the tissue paper tubes -- warm air is less dense than cool air. The veggie creatures -- salt water is more dense than regular water (we watched our creatures float atop the brine). And the color designs on paper -- food coloring mixes with regular water (less dense) but will float on top on brine water (salt water is very dense -- think of the Dead Sea) long enough to create colorful designs on paper. Class dismissed :)
