An instructional segment about Dr. Martin Luther King Jr., whose birthday will be celebrated Monday, also gave students an insight into the common chicken egg.
"Eggs are gooey," said Riley, a fourth-grade student in Amy Hare's class at Bush Elementary.
The classroom activity was lead by Chelsea Baker, a guidance counselor at the Fulton school. Using brown and white eggs, she showed students how they might have different shells, but everyone is the same inside.
"It was just a different (exercise) that I found," she said.
Martin Luther King Jr. Day is a national holiday honoring King's legacy as a civil rights leader in segregated 1950s and '60s America. He was assassinated in Memphis, Tennessee, on April 4, 1968.
Born on Jan. 15, 1929, he became a Baptist minister. He delivered his "I Have a Dream" speech during the 1963 March on Washington and received the Nobel Peace Prize in 1964. His birthday became a federal holiday in 1986.
"Martin Luther King did a lot of great things to help people," Baker told the class of fourth-graders. "Back then, people were judged on the color of their skin."
Students teamed up in pairs, one with a white egg and one with a brown egg. They noted the characteristics of each shell, and then each student broke their egg into a clear plastic cup and compared the innards. They were identical.
"On the outside, we all have different shells, but on the inside, we are the same," Baker said. "Martin Luther King wanted people to know they're all the same, no matter the color of their shells."
Baker said she planned to take all the broken eggs home and fry them up for her goldendoodle, Homer.
"He loves eggs," she said, laughing.
