Measuring Density

Our science experiment was really fun. We used washers to measure different liquids on a scale.  The liquids we measured were cooking oil, glycerin, plain water, and alcohol.  We learned that glycerin has the most density out of these liquids.  Density is how close or spread out molecules are in a substance.   The molecules that were spread out more, weighed less.  So, they had less density.  

For fun, we measured the density of soapy water.  We learned that soap does not effect the amount of density in plain water.
