this week in chemisty class, my class and i had a labed called radioactive half life simulation. in this lab we used pennies to represend decaied substances. each trial we would start off with 100 pennies, idealy we would expect the number of pennies to decrease by half after each half life.
for example 100, 50, 25, 12,6,2,1.
but it didnn't. we end with 1 in the first trial, 3 in the second trial, and two in the last.
after we finished the lab we made a chart and graph to represent all of out data.
mine came out really good.
thankyou,
