In this lesson, we learned about density – the relative “heaviness” of the same amounts of liquid. We used different colors of water with different amounts of salt in them. Half of the students had water with different amounts of salt in them, and half of the students used plain water. The water with equal amounts of salt mixed together, and the water with different concentrations of salt stayed separate, because of the different densities! Continue reading Density Rainbows
