Overview : This activity is designed to teach students about the dangers associated with underground mining.
Essential question: Was there more than one way to go down or come out of the underground shaft? Was anyone found liable for the death of the 41 men who lost their lives in the Milford Mine? Is mining any safer today than in the 1920’s?
; Students will be able to identify the dangers that are associated with underground mining.
; Students will make a T-chart comparing and contrasting dangers of underground mining
back in the 1920’s with the underground mining practices of today by using the internet.
; Students will analyze and evaluate whether or not mining safety has improved since the
Milford Mine disaster in 1924.
