As sixth graders work to determine how they smell something from a distance, they now know that phase change plays an important role since what we smell are gaseous molecules of a substance. We know that molecules at the liquid level are the same at the gaseous level with the exception of the amount of energy present, so our models had to show this. Check out the awesome work of 6th graders who worked to show how water evaporates both due to an increase in heat energy and the air particles bumping into the surface of water.
