“That’s why my brother’s thumbs are so long!” The once silent room erupted with laughter. The students were engaged in creating a fictitious family based on particular genetic traits. One student had the revelation that his biological brother was not, in fact, an alien but that a dominant trait in his family’s lineage must have caused his brother to grow really long “alien” thumbs. This activity was part of Global Doctors: DNA, a Level Up Village (LUV) course I taught last spring at John F. Kennedy Elementary School in Windsor, Connecticut.
