My 7 yr old daughter is home-schooled.  She discovered that black widow 
spiders have 8 eyes when we were designing a pinata.  Later, she was 
watching a film about the human brain.  Now she wants to know why we have 
to use a chunk of brain much larger than the whole black widow spider for 
only 2 eyes.  She can understand answers in biology that are worded for 
grades 7 - 9.  I'm having trouble with this one -- any direction would be 
appreciated.  Thank you!  (We also made a bat pinata and a skunk pinata.)
