Brain Blast

The boys have been working on their science fair projects for several weeks.  

Tucker studied genetics and evolution, distracting DNA from an onion and gathering related facts -- his favorite: humans share half of our genetic material with bananas.

Tolliver investigated flight, looking at wings on both birds and planes. He learned about thrust and lift, and liked reading that some soaring birds' feathers actually weigh more than their bones.

Both boys set up their display boards tonight and promptly ran off to see what their friends brought to share -- wind turbines and water cycles and sound waves and stress balls.

And baby Hank, not one to be left out, had his own small sticker display.
