Learn the concept of density with syrupy sweet goodness
Take 6 of the clear cups and label them with these numbers: 0, 2, 4, 6, 8, 10Add the number of tablespoons of sugar to the cups. 0 gets 0 sugar, 2 gets 2 tablespoons of suger, 4 gets 4 tablespoons of sugar, etc... Stir until the sugar is dissolved. This could take a while for the cups with more sugar!Dye each of the cups a color of the rainbow. 0=red. 2=orange. 4=yellow. 6=green. 8=blue. 10=VioletTake the empty cup and add a little of the violet sugar water to to bottom.
Hold your cup up to the light and you should see the rainbow layers of sugar water. Cool!As you add sugar to the water, you increase the density. In our experiment, the purple cup is the most dense. The red water is the least dense, so it floats.If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT,About the Authors:Sarah Spivey is a San Antonio native who grew up watching KSAT.
