Crayons in the sun

Before the sun

Science  experiment:
A set of crayons were put  in the sun to see what would happen.  

After the sun
The children predicted what would happen when the crayons were put in the sun.  Most of the children knew the crayons would melt.  The next question was a bit more perplexing.  They had to decide if they the color of the color of the crayon would make a difference and why.  

After leaving them in the sun for about an hour on a 70 degree day, the children found that the brown and black crayons melted.  The gray, purple, and dark green were in the beginning stages of melting.  

One child explained that this happened because black absorbs heat and white reflects light.

The children decided if it had been a really hot day, all the crayons would have melted.  We will try again on the next hot day and let you know what we find out.
