Today, my two teen boys (ages 15 and 13) had a co-op class with other homeschool kids their age, and they dissected a dog shark (with dad's help).  The homeschool co-op teen class had about 20 kids there, and few parents.  Amazing what teens will drive 45 minutes for.  LOL

I arrived to pick them and their dad up (I had been with the 2 little ones catching dragon flies by the lake) and they showed me all the cool, icky insides of the shark. 

I learned alot.  Did you know that a sharks liver is filled with oil to help it float better?  Did you know its liver takes up 25% of its body weight?

A lot to learn!
