Tia Jones peered at the flash cards spread across the stage as her partner, Alexa Jones, slid them back and forth.
The girls, both fourth-graders at Ann Arbor’s Dicken Elementary, were trying to match cards showing characteristics of Earth with cards showing characteristics of Mars.
The activity was part of a visit to Dicken by Doug Lombardi, the education and public outreach manager for Phoenix, NASA’s 2007 mission to Mars. Lombardi also visited King Elementary while in town.
