First let’s talk about the basics

        Mass-


        Volume-


        Density-


Now let’s see density (2 Visuals)

        The Pear vs The Apple

        The Bowling ball vs The Golf Ball

How do you figure out density?

______Mass ___________              = Density g/l
Volume of a cylinder = ∏r2h

                        Mass(g)                Volume(cm3= l)    Density (g/cm3)

                         Who is Denser: Yellow, Blue or Red

Hypothesis-


Procedure-

   1) Place 3 color labeled beakers (yellow, blue, red) on the hot plate and add 300ml
      of water to each beaker.
   2) Turn on hot plate and add 5 drops of food coloring to the appropriately labeled
      beaker.
   3) Add 5 sugar cubes to the red colored beaker
      Add 3 sugar cubes to the yellow colored beaker
      Add 0 sugar cubes to the blue colored beaker
   4) Stir liquid and when sugar has dissolved you are ready to begin
      MAKE SURE LIQUID IS NOT BOILING
   5) The goal is to layer the liquids.
   6) Stick your straw in the least dense liquid and place finger over the straw
   7) Place straw in the second least dense liquid and release finger and get the straw
      suck up the liquid and then place your finger over it.
   8) Lastly repeat step 7 with the densest liquid.
