Clean Captain/The Moment of Tooth

Elinor models the foundational practices of science inquiry and engineering design -- including her amazing powers of observation and willingness to ask questions and investigate. When she encounters something she doesn’t understand, like why birds have feathers or how tiny ants build massive anthills, she just can’t let it go until she figures it out.
