It is tons of fun to build Legos with my elementary school students. Anything that I create is light years ahead of them developmentally, so they think I'm the coolest Lego builder ever. One day I happened to build a tall tower. One of our 4th grade boys slipped me a comment as he walked by.
"Oh, that looks just like DNA! Umm, what does that stand for again?"
Feeling excited to actually use my biology degree in some form after graduating, I said matter-of-factly, "Deoxyribonucleic acid!"
