Density and Filtration



Nate's science experiment focused on water Density.  The more molecular matter contained in an object, the higher its density and the more it weighs. An egg will not float in regular tap water, but salt water is more dense than tap water, so it can sustain the weight of the egg. The egg floats.  Great Job Nate!

Abby's experiment was about water filtration.  As you see in the picture, Brandon was her willing participant tasting her filtered water.  Did you know that God created a water filtering system on earth?  The layers of our earth -- sand and rock naturally filter our water before it collects in aquifers  under the ground.  And I thought we invented the concept of filtering water!  God's creation never ceases to amaze!  Great experiment, Abby!
