Does Sunscreen Really Work??--an experiment

 We have had nothing but sunshine and hot temperatures for the last month...in fact, we are in the middle of a drought.  This past week, Laura received a terrible sunburn, so I set out to demonstrate the importance of sunscreen use.  I saw this experiment somewhere out there in the world wide web.
Fold a piece of black construction paper in half.
Cover one side of the paper with sunscreen...we used 50 spf...We went a little overboard with the sunscreen, after the initial globbing...we rubbed most of it off the paper.
 After about 2 hours in the sun, we found these very impressive results....sunscreen definitely protected the paper for the suns harmful rays.
 After using the construction paper, I wondered what results we would get using our sun sensitive paper.
 At first, I made a traditional sunprint.
 Scissors...The paper begins dark blue...what the sun hits, it lightens, leaving a great print of the scissors.
 We then made a circle with sunscreen on the paper and then headed outdoors.
 After a couple minutes, these were are results...Sunscreen once again provided plenty of protection against the sun.
Make sure you wear your sunscreen everyone!!
